CentOS 7.4 fails to boot as Xen PV guest: resurfaces (now also) with centosplus kernel 693.11.6.el7
by David Groep 08 Jan '18

08 Jan '18

Dear all, Maybe I'm the only one - so before filing it as a bug: it appears that the latest set of kernel patches in 3.10.0-693.11.6.el7 makes issue 0013763 "CentOS 7.4 kernel (3.10.0-693*) fails to boot as Xen PV guest" re-surface *also* with the CentOS PLUS kernel. But maybe in a different way ... Thanks to the (great!) quick work on making the plus kernel available (in #14330, thanks for that!) I was able to test the following combinations: - 3.10.0-693.11.6.el7.centos.plus works fine on XenServer 7 HVM guests - 3.10.0-693.11.1.el7.centos.plus works fine on XenServer 7 XenPV guests - 3.10.0-693.11.6.el7.centos.plus crashes on boot for XS7 XenPV guests immediately after the boot stage where the PS/2 drivers are loaded Crashing does not depend on the amount of VM memory or #cores/sockets. Also, the tell-tale "mm/vmalloc.c" failure output is no longer present. The system 'just' crashes (with the kernel log lines as below) around the time of the i8042 controller probing. Obviously the stock upstream 3.10.0-693.11.6.el7 crashes as well for XS7 XenPV guests, but that was to be expected as per 0013763. It crashes in the same way, around the time of the i8042 probes. Can anyone (maybe bill_mcgonigle?) reproduce the issue? Did the KPTI patches break the XenPV fixes in CentOS Plus per 13763? Or is this a new XenPV issue? Interestingly, the crash is now sudden and (even at loglevel=7) without further information. The crash after the i8042/mousedev is (I think) unrelated to these devices, since the system crashes in the same way even with "i8042.debug i8042.nokbd i8042.noaux i8042.dumbkbd i8042.nomux i8042.noloop i8042.nopnp psmouse.proto=bare" added to the kernel command line (and then you don't see any PS/2 and mousedev). So something immediately after the mousy things triggers the crash: 0.2293541 io scheduler cfq registered 0.2295071 pci_hotplug: PCI Hot Plug PCI Core version: 0.5 0.2295241 pciehp: PCI Express Hot Plug Controller Driver version: 0.4 0.2301241 Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled 0.2306111 Non-volatile memory driver u1.3 0.2306601 Linux agpgart interface u0.103 0.2307641 crash memory driver: version 1.1 0.2308301 rdac: device handler registered 0.2308741 hp_sw: device handler registered 0.2308851 emc: device handler registered 0.2308941 alua: device handler registered 0.2309491 libphy: Fixed MDIO Bus: probed 0.2310301 ehci_hcd: USB 2.0 'Enhanced' Host Controller CEHCI) Driver 0.2310471 ehci-pci: EHCI PCI platform driver 0.2310671 ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver 0.2310791 ohci-pci: OHCI PCI platform driver 0.2310951 uhci_hcd: USB Universal Host Controller Interface driver 0.2311581 usbcore: registered new interface driver usbserial 0.2311741 usbcore: registered new interface driver usbserial_generic 0.2311941 usbserial: USB Serial support registered for generic 0.2312291 i8042: PNP: No PS/2 controller found.

Bug in gnome-control-center and network edit module in Centos 7.4
by Gregory P. Ennis 07 Jan '18

07 Jan '18

Everyone, I have been having a problem in setting up gateway/routers with Centos 7.4 machine and finally figured out the problem today. I am not sure if this bug occurred first in 7.3 but it is definitely in 7.4. I have other gateway routers that were created at the beginning of the Centos 7 that have been working perfectly even through the upgrades to 7.3 and 7.4, but the new gateways I have created would not work. It seems simple now that I have the solution, but it took me an embarrassingly too long a time to debug and resolves the problem. The problem appears to me to be a bug in the new gnome-command-center when using the network module to add or edit network interfaces. The problem that I identified is that the network module requires the user to enter a gateway ip address even on the internal networks. Normally the gateway ip address is left blank on the internal interfaces, and is only filled in on the external interface. I was never able to get the gui using the network editor within the gnome-control-center to be able to remove the gateway ip address from the; internal interfaces; I was forced to enter something, and I entered the external gateway ip address. However, to bypass and fix this problem, the gateway ip address is easily removed by editing the appropriate file or files in : /etc/sysconfig/network-scripts/ifcfg-emp3s0 /etc/sysconfig/network-scripts/ifcfg-emp4s0 The network editor in the gnome-control-center module required the entry of a gateway ip address. I had entered the gateway for the external ip address in this field, and all I did to solve the problem is to delete "GATEWAY=x.x.x.x" from both of the above files. This allowed both of the new gateway machines I have recently created to work like they should. Hope this saves someone else some time. Greg

Intel Flaw
by Chris Olson 05 Jan '18

05 Jan '18

How does the latest Intel flaw relate to CentOS 6.x systems that run under VirtualBox hosted on Windows 7 computers? Given the virtual machine degree of separation from the hardware, can this issue actually be detected and exploited in the operating systems that run virtually? If there is a slow down associated with the fix, how much might it impact the virtual systems?

Issues with qt-creator from EPEL 7
by Toralf Lund 04 Jan '18

04 Jan '18

Hi, Is anyone here using the "EPEL" package for qt-creator on CentOS 7? I'm having a few issues with it, and I though I'd run them by the list before I try Qt Forums or whatever (since they could be specific to the above mentioned build.) Most notably, 1. If I click on an error message in the "Issues" list after compilation (to display source code related to the error), I sometimes get a "File not found" message *if the file in question is already open*. If I close the file and repeat, the same file opens just fine. 2. There is something slightly odd about the icons in the display. In particular, when I open the search panes, I sometimes get buttons with labels "Find Previous" and "Find Next", but at other times, those same buttons have arrow icons. Has anyone else seen something like this? - Toralf

Gtkcdlabel + cdlabelgen on CentOS 7 ?
by Nicolas Kovacs 03 Jan '18

03 Jan '18

Hi, I've been using the nifty little application Gtkcdlabel for making CD and DVD covers since 2005, if I remember correctly. Later versions are written in Python, and it's a graphical frontend to the cdlabelgen utility. The application doesn't look very well maintained, since the 1.15 release dates back to 2011. Nevertheless, I've been successfully running it on Slackware Linux until the latest 14.2 release. I'm currently trying to install it on CentOS 7, and I'm only having a partial success, with a showstopper. Here's what I could manage so far. The 'cdlabelgen' command line utility is available on EPEL, so I installed that. I downloaded Gtkcdlabel on the project site: http://gtkcdlabel.sourceforge.net/ The installation process takes you back 25 years, since it amounts to this: # tar xvjf gtkcdlabel-1.15.tar.bz2 -C / This installs the application in /usr/bin/gtkcdlabel.py along with a new desktop entry (and the ugliest icon on the planet). The application shows OK when running it, but PostScript file generation fails. I launched it from a terminal by invoking gtkcdlabel.py, filled out a few fields like Title and Subtitle and then clicked on Preview. Normally this is supposed to launch the PDF viewer (/usr/bin/evince in the default configuration). And it launches, except it gets stuck here, since nothing is generated. Under the hood, in my terminal, I get the following string of error messages: (libspectre) ghostscript reports: invalidfont -10 (libspectre) ghostscript reports: invalidfont -10 (libspectre) ghostscript reports: invalidfont -10 (libspectre) ghostscript reports: invalidfont -10 (libspectre) ghostscript reports: invalidfont -10 I checked, and ghostscript as well as ghostscript-fonts are installed. Which leaves me clueless. Any help would be greatly appreciated, since I've been using this application for years on a daily basis.

Identifying Official CentOS AWS AMIs
by Paul Heinlein 02 Jan '18

02 Jan '18

I'm trying to automate identification of CentOS AWS images. It appears that official CentOS AMIs have an OwnerID value of 410186602215, but I'm not sure if that value is transient or specific to one or more AWS regions. Is there a maintainer lurking here that can confirm or deny? Here's the base query I'm testing: aws ec2 describe-images \ --owners 410186602215 \ --output text \ --query 'reverse(sort_by(Images, &CreationDate))[?starts_with(Description, `CentOS Linux 7`)].[ImageId, CreationDate, Description]' -- Paul Heinlein heinlein(a)madboa.com 45°38' N, 122°6' W

DHCP timeout and mysteriously dropping IP address
by Jason Edgecombe 02 Jan '18

02 Jan '18

Hi everyone, I'me having trouble with a CentOS 7 guest running on a Hyper-V host. For some reason, the CentOS guest randomly drops its IP address. Running "systemctl restart NetworkManager" on the console will restore IP connectivity without a reboot. I think that DHCP is timing out, but I'm not sure what to do about it. Is there a way to tell NetworkManager to keep trying after a timeout? Here are the versions of the kernel and NetworkManager: Kernel: 3.10.0-693.11.1.el7.x86_64 NetworkManager: 1.8.0-11.el7_4.x86_64 Here are some pertinent logs: Dec 23 03:30:26 myhost kernel: hv_utils: Using TimeSync version 3.0 Dec 23 03:30:27 myhost systemd: Time has been changed Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.3750] device (eth0): link connected Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.3762] device (eth0): DHCPv4 lease renewal requested Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.3889] dhcp4 (eth0): canceled DHCP transaction, DHCP client pid 7936 Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.3890] dhcp4 (eth0): state changed bound -> done Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.3899] dhcp4 (eth0): activation: beginning transaction (timeout in 45 seconds) Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.4487] dhcp4 (eth0): dhclient started with pid 33165 Dec 23 03:30:33 myhost dhclient[33165]: DHCPREQUEST on eth0 to 255.255.255.255 port 67 (xid=0x5cb111f1) Dec 23 03:30:33 myhost dhclient[33165]: DHCPACK from xxx.xxx.36.1 (xid=0x5cb111f1) Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.5824] dhcp4 (eth0): address xxx.xxx.37.53 Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.5825] dhcp4 (eth0): plen 23 (255.255.254.0) Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.5826] dhcp4 (eth0): gateway xxx.xxx.36.1 Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.5826] dhcp4 (eth0): lease time 7200 Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.5826] dhcp4 (eth0): nameserver 'xxx.xxx.0.20' Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.5826] dhcp4 (eth0): nameserver 'xxx.xxx.0.30' Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.5826] dhcp4 (eth0): domain name 'example.com' Dec 23 03:30:33 myhost NetworkManager[788]: <info> [1514017833.5826] dhcp (eth0): domain search 'example.com.'
