kvm & permission denied
by Gregory P. Ennis 15 Jul '18

15 Jul '18

Everyone, I am trying to install KVM on a desktop unit as a lab project with the hope of being able to use kvm on one of our office servers after I learn how. So far I am very low on the learning curve. I have used the guide to make the installation : https://www.linuxtechi.com/install-kvm-hypervisor-on-centos-7-and-rhel- 7/ The installation seemed to go well, but when I tried to add Fedora 27 with virt-manager I have continued to get file permission errors. I have tried turning selinux off, and making sure the directory permissions are 777 and the file permissions are 666, but have not been able to succeed. A google search demonstrates others have had this problem, and I have tried many of the fixes that have been recorded, but no success. I am running : CentOS Linux release 7.5.1804 (Core) with 3.10.0- 862.6.3.el7.x86_64 kernel CPU : AMD FX(tm)-6300 Six-Core Processor I am using the root account through a konsole interface to activate virt-manager. The Error Message from virt-manager is : Unable to complete install: 'internal error: process exited while connecting to monitor: 2018-07-15T13:55:37.836269Z qemu-kvm: -drive file=/home/greg/Downloads/Fedora/f27/Fedora-Workstation-Live-x86_64-27- 1.6.iso,format=raw,if=none,id=drive-virtio-disk0: Could not open '/home/greg/Downloads/Fedora/f27/Fedora-Workstation-Live-x86_64-27- 1.6.iso': Permission denied' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 89, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 2545, in _do_async_install guest.start_install(meter=meter) File "/usr/share/virt-manager/virtinst/guest.py", line 498, in start_install doboot, transient) File "/usr/share/virt-manager/virtinst/guest.py", line 434, in _create_guest domain = self.conn.createXML(install_xml or final_xml, 0) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3658, in createXML if ret is None:raise libvirtError('virDomainCreateXML() failed', conn=self) libvirtError: internal error: process exited while connecting to monitor: 2018-07-15T13:55:37.836269Z qemu-kvm: -drive file=/home/greg/Downloads/Fedora/f27/Fedora-Workstation-Live-x86_64-27- 1.6.iso,format=raw,if=none,id=drive-virtio-disk0: Could not open '/home/greg/Downloads/Fedora/f27/Fedora-Workstation-Live-x86_64-27- 1.6.iso': Permission denied The /var/log/message entries associated with the above error message is the following : Jul 15 08:55:37 HmGp libvirtd: 2018-07-15 13:55:37.922+0000: 1643: error : qemuMonitorOpenUnix:385 : failed to connect to monitor socket: No such process Jul 15 08:55:37 HmGp libvirtd: 2018-07-15 13:55:37.927+0000: 1643: error : qemuProcessReportLogError:1912 : internal error: process exited while connecting to monitor: 2018-07-15T13:55:37.836269Z qemu-kvm: -drive file=/home/greg/Downloads/Fedora/f27/Fedora-Workstation-Live- x86_64-27-1.6.iso,format=raw,if=none,id=drive-virtio-disk0: Could not open '/home/greg/Downloads/Fedora/f27/Fedora-Workstation-Live-x86_64- 27-1.6.iso': Permission denied Thanks ahead of time for your help.

ssm vs. lvm: moving physical drives and volume group to another system
by Mike 15 Jul '18

15 Jul '18

I did the following test: ############################################### 1. Computer with Centos 7.5 installed on hard drive /dev/sda. Added two hard drives to the computer: /dev/sdb and /dev/sdc. Created a new logical volume in RAID-1 using RedHat System Storage Manager: ssm create --fstype xfs -r 1 /dev/sdb /dev/sdc /mnt/data Everything works. /dev/lvm_pool/lvol001 is mounted to /mnt/data. Files and folders can be copied/moved, read/written on /mnt/data. ############################################### 2. I erased CentOS 7.5 from /dev/sda. Wrote zeros to /dev/sda using dd. Reinstalled CentOS 7 on /dev/sda. Completed yum update - reboot - yum install system-storage-manager. RedHat system storage manager listed all existing volumes on the computer: [root@localhost]# ssm list -------------------------------------------------------------------------------------- Volume Pool Volume size FS FS size Free Type Mount point -------------------------------------------------------------------------------------- /dev/cl/root cl 65.00 GB xfs 64.97 GB 63.67 GB linear / /dev/cl/swap cl 8.00 GB linear /dev/lvm_pool/lvol001 lvm_pool200.00 GB xfs 199.90 GB 184.53 GB raid1 /mnt/data /dev/cl/home cl 200.00 GB xfs 199.90 GB 199.87 GB linear /home /dev/sda1 4.00 GB xfs 3.99 GB 3.86 GB part /boot -------------------------------------------------------------------------------------- [/CODE] So far, so good. The new CentOS7 install can see the logical volume. Mounted the volume: ssm mount -t xfs /dev/lvm_pool/lvol001 /mnt/data Works. cd to /mnt/data and I can see the files left on the volume from the previous tests. Moving/copying/read/write -- works. ################################################### 3. Is it safe to assume when using RedHat System Storage Manager it's not necessary to use the lvm commands (vgexport and vgimport) to move two physical drives containing a logical volume in raid 1 from one computer to another? Thanks for your help and guidance.

Re: [CentOS] Firefox 60.0.1.0 ESR Progress?

Thanks for the idea, I'm not in a hurry and don't have a desire to hand-jam upstream versions of firefox onto desktops. I just need to track progress on the patch release and report an ETA to our cyber security team. I just figured CentOS had a fancy devops CI/CD system somewhere that I could keep tabs on to watch what's going on as patches get built, tested and published.

Semi-OT: LSI raid card sorta....
by mark 11 Jul '18

11 Jul '18

I've got a box running C7, just updated (yesterday). It had an onboard RAID controller, and an HBA. I just installed a new, additional RAID card, all LSI. MegaCli64 only sees one controller. I can't seem to find the magic to see the others. I *know* the new card is a MegaRAID - the box it came in says so. The system sees it 1:00.0 RAID bus controller: LSI Logic / Symbios Logic SAS1078 PCI-Express Fusion-MPT SAS (rev 04) 42:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS-3 3108 [Invader] (rev 02) 43:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS3008 PCI-Express Fusion-MPT SAS-3 (rev 02) I've connected a RAID box that we had to it. I'm trying to import the foreign configuration and bring it online. I really can't reboot the system for (literally) another month (the maintenance window); I saw the firmware interface, but for Reasons, couldn't do it then, and figured I'd be able to to it with MegaCli64, but so far, nope. -AdpAllinfo gets only one. Clues? mark

FYI: Useful to know on pdf printing
by mark 11 Jul '18

11 Jul '18

This is just an FYI, folks. We've got this large poster printer. We had some, er, environmental issues, let us say, and first I had to recreate the .ppd (HP "doesn't support printing from Linux, and the one a former coworker extracted from the Mac package... was for a 23", not this 44"). Then... I was trying to print from a 6.9 box. I hadn't rebuilt the box as C 7, because until the Incident, I'd been using acroread, so I was looking to see if something else would print correctly. Using evince in 6.9, 100% of the time, the printer's web page would tell me it was receiving, then the job would vanish, and the logs on the Linux side would tell me broken pipe. I did, however, print a test page from cups with no problem. So, yesterday, I updated to6.10, and then installed okular... and it printed perfectly, with no issues. Apparently, evince has some issue, either printing a .pdf, or there's something in my hacked .ppd that makes it gag, but okular is happy with. Just thought I'd let y'all know, so you could push it onto the stack, available if you run into this issue. mark

hi guys I wonder if any of you might be using SFN6122F-R7 SFP+ (SFC9000, same firmware everywhere, Centos 7.5 too. I'm trying poor man's setup to get the servers onto 10GbE network. Setup is such that three Dell R815 are connected to each other, each has one Solarflare(SFP ports) and each Solarflare is set as net-team(both ports on a card are net-team device) with runner in broadcast mode. And it all seems to work, they ping each other, iperf okey. The problem, big problem is that when traffic start to flow between all three servers simultaneously, with rsync for example, then!! one box gets shoot in the head, hard reset, gone. Every time same one box. Sure there are some bits that run on that one box that are not on the other two. Now, I know you would normally put it via a switch, but like I said: poor man's config, but you would not expect system to die like this neither, right? many thanks, L.

hi guys, shellinabox, do you use it? I in pretty vanilla setup get selinux denials and cannot login. Selinux says: #============= unconfined_service_t ============== #!!!! The file '/usr/bin/bash' is mislabeled on your system. #!!!! Fix with $ restorecon -R -v /usr/bin/bash allow unconfined_service_t unconfined_t:process transition; but that does not seem right to me, to allow such a transition, right? many thanks, L.

CentOS 7 + MATE : no sound in Firefox
by Nicolas Kovacs 08 Jul '18

08 Jul '18

Hi, I recently switched my main workstation running CentOS 7 from KDE to MATE. Migration went well, but now I have a couple issues. First things first. I have no sound in the Firefox browser. Applications like Audacious, VLC or MPlayer have sound, but Firefox is mute. Any idea how I can fix that?

two 2-node clusters or one 4-node cluster?
by Gianluca Cecchi 07 Jul '18

07 Jul '18

Hello, I'm planning migration of current two clusters based on CentOS 6.x with Cman/Rgmanager going to CentOS 7.x and Corosync/Pacemaker. As the clusters and their services are on the same subnet, and there no particular security concerns differentiating them, I'm also evaluating the option to transform the two clusters into a unique 4-node one during the upgrade. Currently I'm testing a virtual 4-node CentOS 7.4 cluster inside oVirt 4.2 and things seem to behave well. Before going further in deep with tests and so on, I'd like to check with the community about how many CentOS 7.x clusters composed by more than two nodes are in place and what are the feedbacks on them in terms of incremented latency/communication, ecc scaling out. Also general feedback related to CentOS 6 and scalability of cluster nodes number is welcome. Thanks in advance, Gianluca

Bash question
by Jerry Geis 07 Jul '18

07 Jul '18

Hi All, I am trying to build a command line with spaces in the argument. This demonstrates what I am trying to do. Clearly the first two commands work fine. However, the last 4 lines to not. /opt/libreoffice5.4/program/soffice.bin --headless --convert-to csv "/tmp/file.xlsx" /opt/libreoffice5.4/program/soffice.bin --headless --convert-to csv "/tmp/file 2.xlsx" MSG="file 2" MSG="csv \"$MSG\"" echo $MSG /opt/libreoffice5.4/program/soffice.bin --headless --convert-to $MSG I am trying to make a variable containing spaces which is MSG. Then add to that variable the argument csv. The "echo" above prints the write stuff. But when I try to use it in the last command its no longer valid and says Source file could not be loaded. What am I missing? much searching hinted to arrays and using \$ but I could not get that to work. Thanks. Jerry

weird slowdowns with recent CentOS 6 update
by Noam Bernstein 05 Jul '18

05 Jul '18

I just spent a while trying to debug some weird slowdown issues, and I thought I’d let the mailing list know in case it helps anyone else, or someone has a cleaner solution (or better ways of debugging the real issue). Just by way of context, we have a cluster using Infiniband and CentOS 6 (up to the latest patches as of a couple weeks ago, so 6.9+anything newer) and OpenMPI 3.1.0. Most of the nodes are "Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz” or "Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz”, currently with kernel .6.32-696.30.1.el6.x86_64 Recently (I believe when we upgraded to that kernel, but not 100% sure that's really when it started), certain parallel floating-point-compute intensive jobs would sometimes (maybe 1 time in 20) run very slowly. The overall speed was reduced by about a factor of 2, but the slowdown appeared to be localized to specific routines, which would go from taking ~1s to ~50-100s. I first assumed it had to do with communication, but as I made the timing information more fine grained, it became clear that nearly trivial loops like DO I=1,GRIDC%RL%NP DWORK1(I,ISP)= REAL( DWORK(I,ISP) ,KIND=q) ENDDO were a large part of the problem. The only thing I could find after poking around that was at all odd is that when this happened, khugepaged would be taking 100% of cpu for tens of seconds on the affected nodes. It appears, although it’s not completely certain yet (since the problem appears rarely enough to that it’s hard to definitively rule out), that disabling THP by putting “never” in /sys/kernel/mm/transparent_hugepage/enabled and /sys/kernel/mm/transparent_hugepage/defrag fixes the problem. I guess I am also still wondering what exactly khugepaged does, and what kind of problems I should worry about because I disabled it. The documentation I’ve found for it doesn’t really explain what the transparent huge pages are good for. Noam

They both (C6 and C7 versions) require many non OS tools to build. For CentOS-7 .. we need the rust-toolset, llvm-toolset, and devtoolset-7, to get the firefox to build. For CentOS-6, we need less items (no llvm-toolset required .. all the rest is required). But, there is no released source code for the EL6 version of rust-devtoolset upstream. I am working on this now .. but we had the 6.10 release and the also 32 other items that dropped for CentOS-7 (both of which are now done).

gpg2 (GnuPG) Security Update for CentOS 6.10
by nschehovin＠yahoo.com 04 Jul '18

04 Jul '18

Where do I get an update for gpg2 (GnuPG) for CentOS 6.10 that is compliant with CVE-2018-12020? I'm trying to update gpg2 (GnuPG GNU Privacy Guard) on my fully updated CentOS 6.10 computer to comply with CVE-2018-12020. My system has gpg2 package gnupg2-2.0.14-8.el6.x86_64.rpm This package does not appear to be compliant with CVE-2018-12020. I can not find and update anywhere. I have tried downloading the upstream version 2.2.8 from GnuPG.org but am having trouble building it for CentOS 6.10 primarily due to a requirement for a newer version of glibc. I'm getting the error undefined reference to 'clock_gettime' and have not been able to resolve it Any suggestions on where to download the update or when an update might be available or how to build gpg2 version 2.2.8 for CentOS 6 is appreciated. Thanks,Ed

Samba issues with Win 10
by mark 04 Jul '18

04 Jul '18

Hi, folks, Just ran into a problem: someone with a new laptop, running Win 10, version 1709, tried to map their home directory (served from a CentOS 6.9 box, and it fails, with Windows complaining that it no longer supports SMBv1, and if you go to their site, you can install support for that manually.... The server running samba can *not* be updated to 7 - we have a lot of stuff based off it, and most of our users use it, one way or another, so it's a major thing when we do finally upgrade (or, more likely, replace the server). Has anyone run into this, and if so, any workarounds on the Linux end? mark

ZFS on Linux repository
by Gionatan Danti 03 Jul '18

03 Jul '18

Hi list, we all know why ZFS is not included in RHEL/CentOS distributions: its CDDL license is/seems not compatible with GPL license. I'm not a layer, and I do not have any strong opinion on the matter. However, as a sysadmin, I found ZFS to be extremely useful, especially considering BTRFS sad state. I would *really* love to have ZFS on Linux more intergrated with current CentOS. From what I know (and I can go wrong, obviously), while the incompatible licenses prevent CentOS from shipping it, nothing should prevent to have a package for enabling *its repository*, better yet the kmod-enabled one. I was thiking to something as a ZFS SIG, where we can simply issue "yum install zfs-sig" and have the correct kmod-enabled repository enabled. I searched the list but I did not found anything regarding native ZFS. Any feedback on the matter is welcomed. Thanks. -- Danti Gionatan Supporto Tecnico Assyoma S.r.l. - www.assyoma.it email: g.danti(a)assyoma.it - info(a)assyoma.it GPG public key ID: FF5F32A8

CentOS7/Mate Qt bugs/features?
by James Pearson 02 Jul '18

02 Jul '18

We have recently migrated from CentOS6/Gnome to CentOS7/Mate - and have noticed 'glitches' with some Qt applications that appears to be linked to the 'org.mate.Marco.general' 'compositing-manager' setting - and wondered how we 'fix' the issue ... Below is a PyQT4 python script that shows the issues: 1. With 'compositing-manager' set to 'true' (I believe the default setting): gsettings set org.mate.Marco.general compositing-manager true Running the script and the window background is transparent - which is fine However, if the pull down menu is selected and the 'Toggle' button pressed, the menu stays on the screen - and stays put even if the window is moved 2. With 'compositing-manager' set to 'false' : gsettings set org.mate.Marco.general compositing-manager false Running the script and the window background is no longer transparent - which is not good, but the pull down menu issue is fine ... We're using Nvidia cards with the Nvidia drivers - but I can also reproduce the issue on a Vmware player instance It would be good to know if anyone else can reproduce this with Mate ? Using CentOS7/Gnome3 works as expected (transparent background and pull down menu is fine) Anyone have any idea what the problem(s) might be and how to fix it/them ?

C++11 and GCC 5+
by Alice Wonder 02 Jul '18

02 Jul '18

This may be common knowledge to some, but it was new to me. Libraries that use C++11 and are compiled with GCC 4.8.x that CentOS 7.x has are NOT binary compatible with GCC 5.x or newer. It seems to only effect C++11. What you have to do - create /opt/gcc55 (or whatever) Rebuild any libraries that use C++11 that you need in something compiled with GCC 5+ and install them within that prefix. Then point to them in that prefix when building what you need to build. -=- The Linux runtime linker seems to get it right (as long as you have /opt/gcc55/lib64 in path) and not load wrong version of library, so you don't need to use rpath. But you do need to have a version of the dependency compiled with the GCC you want available at both compile time and runtime. -=- I ran across this issue when building Audacity 2.2.2 - which does not build with GCC 4.8.5. The problem libraries: * flac * vamp-sjdk-plugin * wxGTK3 All three of those use C++11 and therefore needed to be rebuilt with GCC 5.5.0 (what I used for building Audacity) Just thought I'd pass it along.

dhcpd.conf for balance-rr bonding
by Nurdiyana Ali 02 Jul '18

02 Jul '18

Hi, I am trying to configure linux bonding using balance-rr configuration. I could not find a way to configure dhcpd.conf for this purpose and failed miserably when I tried the following (dhcpd just failed): host servername { hardware ethernet [mac address interface #1] ; hardware ethernet [mac address interface #2] ; fixed-address 10.0.10.6; } In my understanding balance-rr would be issued a single IP address but using 2 mac addresses in round-robin mechanism. If this is true, how do I configure DHCPD to issue single IP address to 2 different MAC? Sincerely, Nurdiyana Ali.

Replacement web server time - catalog CPAN and PEAR installs
by Gary Stainburn 29 Jun '18

29 Jun '18

I'm looking to replace an OLD Fedora web server with a Centos 7 one. I'm currentlly in the process of documenting what is on the server ready to install the new one. While most things have been done with RPMs, some installs have had to be done via CPAN for Perl and PEAR for PHP. Is there a way of getting a list of everything that has been installed using these tools?

VMWare Workstation 14 on CentOS7
by wwp 29 Jun '18

29 Jun '18

Hello there, I'm encountering blocking issues with VMWare Workstation v14/v12 on CentOS 7. The issue is that any Linux guestsystem will get network-disconnected after a short while. I tried w/ brand new guest installs, guests coming from a v12 WS. Tried different guest network settings, I always get disconnected. I found several cases like this on the Web, but couldn't see any working solution yet. My CentOS7 runs 4.9.75-204.el7.centos.x86_64 kernel. On my previous CentOS 6, still alive, v12 works like a charm. Does anyone have experience with this? Regards, -- wwp

multipath recipe for an enclosure ?
by lejeczek 28 Jun '18

28 Jun '18

hi guys, In hope that some experts roam around I post this one question - how do you multipath disks(all disks) that sit in one specific SAS enclosure? Blacklist everything else. And I'm hoping for something like "globing", so you do not want to go through it on by single disk/wwin basis. some experts?(or maybe even not, it could be that I do not get it) many thanks, L.

I do not want this ever asking for an IP. There's no management port, dunno why, but the only thing where it should be is a couple of pieces of thin, bent metal, and nothing, apparently, damaged. I do see one option of "defgw macaddr" - is that supposed to be a MAC external to the server, or can I use the MAC of eth1 (or whatever the stupid, unrememberable name is)? mark

Postfix, system notifications and local servers
by Nicolas Kovacs 28 Jun '18

28 Jun '18

Hi, I have CentOS 7 running on half a dozen public servers. For some stuff like automatic updates using yum-cron, I have Postfix installed with a relatively basic configuration. This allows me to send important notifications to my mail address info(a)microlinux.fr. When there's a batch of updates, I get one mail per machine, so I can check quickly if everything went OK without having to connect to the server. Now I'd also like to use this setup on machines that aren't in a datacenter and facing the Internet. For example, servers that have "dummy" hostnames like nestor.microlinux.lan or sauvegarde.scholae.lan. Is there a way I can setup Postfix so this machine can send an e-mail to info(a)microlinux.fr, even if 'hostname --fqdn' returns a "dummy" hostname?

Semi-OT: ipmitool or ipmicfg: set BMC to use NIC 2
by mark 26 Jun '18

26 Jun '18

The man page isn't helping, nor have I been able to find examples that work. For example, the man page claims I can do ipmitool lan get active, and I try, and it says, "invaling lan command, get". Do I set the MAC address for the lan to NIC 2? Anyone have a clue - I do *not* want martians on the real network. mark

lightdm + xorg.conf + nvidia driver

Hello CentOS-Community, I have to maintain a server that should be useable with VNC and some software requires to run VirtualGL. Also a nvidia graphic card is installed.

Lightdm should be running, otherwise it is not possible to run virtualgl in an appropriate way. I had the same/similar issues on three different servers with three different nvidia graphic cards.

Specifying different options for different " smb" type gvfs mount
by Toralf Lund 26 Jun '18

26 Jun '18

Hi, I'm trying to use smb:// URLs with gvfs-mount and/or similar desktop functionality to access SMB shares on different servers that support different protocol versions and features. With some of the servers, mount will fail with a default configuration, but I have been able to make it work by editing some of the "client" options in /etc/samba/smb.conf. The problem is, those changes will cause the operation to fail on other servers; I can't seem to find a combination of settings where all shares will work. Does anyone know if there is an alternative way to specify client options that will apply to only specific URLs/shares, and not everything of SMB type? Note that I might be able to get by if I could set the "max protocol" individually for the different file-systems or URLs. I known that I might use mount.cifs and related "fstab" entries as an alternative, but its password handling seems a lot less convenient. I'm on a CentOS 7 system where all updates had been applied as of a few days ago. Thanks, - Toralf
