by Sandro Bonazzola 17 Oct '17

17 Oct '17

Hi, I won't be able to attend today Virt SIG meeting. On KVM side, there should be a RHEL update in the coming days, an update to qemu-kvm-ev will follow (https://bugzilla.redhat.com/show_bug.cgi?id=1501910 ). On oVirt side, upstream is finalizing 4.1.7 release and 4.2.0 beta; Virt SIG repos will be update after the releases. The oVirt 4.2 testing repos are now live on https://buildlogs.centos.org/centos/7/virt/x86_64/ovirt-4.2/ for x86_64, ppc64le, aarch64 Bug queue: - https://bugs.centos.org/view.php?id=12877 can be closed - https://bugs.centos.org/view.php?id=11457 was opened against oVirt 4.0, still valid for 4.1 and 4.2; still missing packages in altarch release mirrors. - https://bugs.centos.org/view.php?id=13747 can be closed - https://bugs.centos.org/view.php?id=13660 can be closed - https://bugs.centos.org/view.php?id=13633 still needed, opstools is still missing packages in altarch release mirrors. - https://bugs.centos.org/view.php?id=13463 I think this has been solved and can be closed - https://bugs.centos.org/view.php?id=13332 I think this has been solved and can be closed - https://bugs.centos.org/view.php?id=13283 still needed, not sure if there's any action needed on my side. - https://bugs.centos.org/view.php?id=12336 was reported on fc25, seems to work on fc26 I think it can be closed. - https://bugs.centos.org/view.php?id=11279 still needed, debuginfo missing for ppc64 and ppc64le packages. -- SANDRO BONAZZOLA ASSOCIATE MANAGER, SOFTWARE ENGINEERING, EMEA ENG VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED.

kernel-plus PXE virt-install with Xen?
by PJ Welsh 11 Oct '17

11 Oct '17

I'm trying to figure out how to replace the vmlinuz and initrd.img from CentOS 7.4 with "fixed" kernel-plus versions in order create CentOS 7.4 VM's. So far I'm stuck booting via 7.3 install, adding new kernel-plus and upgrading to 7.4. I've not found any complete Google answers and was looking for help making sure I choose the correct approach. I've tried to build an initrd.img from a kernel-plus booting system via "mkinitrd -f -v /boot/initrd.img $(uname -r)", but the file size is less than half the one from CentOS 7.4 (17MB -vs- 47MB). I'm not even sure I can just replace those files yet either. Any help going the correct path? Thanks PJ

"Error starting domain: Path '/usr/share/OVMF/OVMF_CODE.fd' is not accessible"
by Craig M 04 Oct '17

04 Oct '17

Recently upgraded my centOS 7 host, and was giving this error after trying to start the guest VM with virt-manager from my desktop: "Error starting domain: Path '/usr/share/OVMF/OVMF_CODE.fd' is not accessible, no such file or directory" I was told on irc that the OVMF package is now part the base centOS repos, so it replaced the installed OVMF package from the repo centos-release-qemnu-ev As a quick workaround to get the VM running again, i was able to do "yum downgrade OVMF" which did: Removed: OVMF.noarch 0:20170228-5.gitc325e41585e3.el7 Installed: OVMF.noarch 0:20150414-2.gitc9e5618.el7 i'm sending this email to ask is there another file i should be using instead of OVMF_Code.fd, for example was it replaced by something else that i should be using ? or is there an issue somewhere else.

Status of reverted Linux patch "tty: Fix ldisc crash on reopened tty", Linux 4.9 kernel frequent crashes
by Pasi Kärkkäinen 20 Sep '17

20 Sep '17

Hello everyone, Recently Nathan March reported on centos-virt list he's getting frequent Linux kernel crashes with Linux 4.9 LTS kernel because of the missing patch "tty: Fix ldisc crash on reopened tty". The patch was already merged upstream here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… but then reverted here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… Nathan confirmed if he applies the patch from 71472fa9c52b1da27663c275d416d8654b905f05 to his Linux 4.9 LTS kernel the bug/problem goes away, so the patch (or similar fix) is still needed, at least for 4.9 LTS kernel. Mikulas reported he's able to trigger the same crash on Linux 4.10: https://www.spinics.net/lists/kernel/msg2440637.html https://lists.gt.net/linux/kernel/2664604?search_string=ldisc%20reopened;#2… Michael Neuling reported he's able to trigger the bug on PowerPC: https://lkml.org/lkml/2017/3/10/1582 So now the question is.. is anyone currently working on getting this patch fixed and applied upstream? I think one of the problems earlier was being able to reliable reproduce the crash.. Nathan says he's able to reproduce it many times per week on his environment on x86_64. Thanks a lot, -- Pasi

change network settings of VM depending on logged in user(s)?
by hw 08 Sep '17

08 Sep '17

Hi, is there a way to disable internet access for a windoze 7 VM depending on which user(s) is/are logged in? It seems windoze 7 doesn´t really support this, especially when you want to disable internet access for the whole machine, so I´m wondering if there is a way to do this when the machine is a KVM-VM running on Centos. The whole VM should only have internet access when a particular user logs in, and preferably for only this particular user.
