Panic with EL7 KVM guest on EL6 host on AMD server with latest kernel
by Simon Matter 18 Jul '18

18 Jul '18

Hi, I have AMD servers running CentOS 6.10 as KVM host and on it guests running CentOS 7.5. Since the latest kernel update on CentOS 6.10, kernel-2.6.32-754.2.1.el6.x86_64, I can't boot the CentOS 7.5 guests with kernel-3.10.0-862.6.3.el7.x86_64 anymore. Reverting CentOS 6.10 host to kernel-2.6.32-754.el6.x86_64 fixes the problem. Screendump of the panic is attached, not very helpful I guess. The CPU models where I could test it are: cpu family : 15 model : 65 model name : Dual-Core AMD Opteron(tm) Processor 2218 stepping : 3 cpu family : 16 model : 6 model name : AMD Athlon(tm) II Neo N36L Dual-Core Processor stepping : 3 Didn't test on newer CPU family yet. I'm wondering, does someone see the same issue? Does it not happen on Intel CPUs? Thanks for any insight. Regards, Simon

Clamd issues on Centos 6.10
by Jay Hart 17 Jul '18

17 Jul '18

Hello all, Been having an issue today that I can't seem to solve, so reaching out to others much more knowledgeable for help/advice/assistance. I ran the software update this morning and installed 134 packages, clamd was one of the packages. Upon completion of the update, I needed to reboot the box. During bootup I got the following issue: Starting Clam AntiVirus Daemon: WARNING: Ignoring deprecated option AllowSupplementaryGroups at line 194 LibClamAV Error: cli_cvdload: Corrupted CVD header LibClamAV Error: Can't load /var/lib/clamav/main.cvd: Malformed database LibClamAV Error: cli_loaddbdir(): error loading database /var/lib/clamav/main.cvd Sat Jul 14 09:04:46 2018 -> !Malformed database [FAILED] Clamd failed to start. I modified the clamd.conf conf file to comment out the deprecated option above, this seemed to allow clamd to start following a second reboot. I followed some suggested actions from the clamd.net site, namely I ensured my DNS was still working, that I could reach clamd.net, and also removed the mirrors.dat and main.cvd files in an effort to get clamd to update via freshclam. When I run 'freshclam -v' I get the following data return: [root@centos clamav]# freshclam -v Current working dir is /var/lib/clamav Max retries == 3 ClamAV update process started at Sat Jul 14 15:09:47 2018 Using IPv6 aware code Querying current.cvd.clamav.net TTL: 1611 Software version from DNS: 0.100.1 WARNING: Your ClamAV installation is OUTDATED!

I tried deleting the mirrors,dat file and re-running freshclam (did not reboot the box between file deletion and command line execution), no effect... Also, I have the default mirror location in freshclam.conf, which seems to be fine considering its been like this for years. I tried to locate the 'country code' paramater but gave that up after I got a headache looking over the documentation. I don't think its relevant to this issue anyway. I'm stuck on how to fix this. Nothing on the web shows what resolution is, nor how to fix it. Seems like I can get and receive emails, but I have no idea if they are being properly scanned. Thanks in advance, Jay

Re: [CentOS] Font related problems with recent FF 60.1

It is most likely because Firefox 60 uses a 'private' gtk3 runtime (which includes its own fontconfig set up) on el6 - as el6 uses gtk2 natively I've reported this problem at: https://bugzilla.redhat.com/show_bug.cgi?id=1601475 James Pearson

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.
