Enforcing 2FA to the CentOS/virt namespace
by Sandro Bonazzola 10 Feb '26

10 Feb '26

Good Morning Everyone, I would like to raise the topic of enforcing 2FA on the entire CentOS/virt namespace on gitlab: https://gitlab.com/CentOS/virt This is something I can do, but before I click the button I'd like to ask: is anyone opposed to this? If not, I'll switch the configuration next week. Thanks in advance for your thoughts! -- Sandro Bonazzola MANAGER, ENGINEERING Red Hat In-Vehicle Operating System Red Hat <https://www.redhat.com/> <https://www.redhat.com/> <https://redhat.com/options> *Red Hat respects your work life balance.

How to debug Ubuntu 8.04 LTS guest crash during install?
by Neil Aggarwal 04 Nov '25

04 Nov '25

Hello: I am using kvm on a CentOS 5.4 server. I am trying to install the TunkeyLinux Core appliance found here: http://www.turnkeylinux.org/core I downloaded the ISO file from the web site. Then, I used this command to intall it: virt-install -n tkl-core -r 512 --vcpus=1 --check-cpu --os-type=linux --os-variant=ubuntuhardy -v --accelerate -c /tmp/turnkey-core-2009.10-hardy-x86.iso -f /var/lib/libvirt/images/tkl-core.img -s 15 -b br0 --vnc noautoconsole When I connect to the VNC console, I get the Turnkey linux options screen. I select Install to hard disk from there and it seems to start the install but crashes during the installer startup. This is repeatable so there has to be a way to debug it. I tried turning on the debug option for virt-install but that did not give me any useful info. Any ideas how to debug this?

asking permissions to contribute to Virt SIG doc
by Fabian Arrotin 03 Jun '25

03 Jun '25

Hi Sandro, When updating qemu-kvm (rebased from new c10s upstream commits) to latest for ppc64le through Virt SIG, I realised that , while announced to centos-devel and also having pushed a centos-release-kvm-power packages in Extras-common repository, I never updated the Virt doc itself (available on https://docs.centos.org/centos-virtualization-sig/) May I just add a subsection about KVM power and so explain how to just add it on Stream 10 (and should be working on RHEL10 and other rebuilds too) ? -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

Enabling back kvm host feature for ppc64le (proposal to join the SIG)
by Fabian Arrotin 16 May '25

16 May '25

Hi all, For CentOS infra needs, we have some ppc64le hosts deployed (Power9 and soon Power10) but the existing machines are still relying on RHEL8, as it was the last enterprise distro version in the RH ecosystem to provide kvm host feature. This was dropped after in the RHEL9 version (and still disabled in Stream10 and so for future el10) I had a look and at least I know that Almalinux people have enabled back what was missing, and so be able to use it as kvm host, and then deploy as usual other guests on top. I'd like to propose to join myself the SIG and create some tags, just for ppc64le, starting with Stream 10 and eventually (time permitting but not the initial goal) do the same for Stream 9/RHEL9. Asking so the chair, Sandro, if he minds me (from the Infra SIG perspective) joining the SIG and start some scratch builds as PoC and then promote builds on the mirror network. As said, as we (CentOS Infra) would rely on these builds, we'd maintain these as long as we'd need ppc64le support in our infra, which we don't consider to drop anytime soon. Opinions, feedback, thoughts ? PS : trying in parallel to reach out to some folks at the Almalinux side, to see if working on patches can be done in parallel -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

Dear Members, The CentOS Virtualization SIG will not be holding regular meetings for the time being. Instead, all discussions and collaborations should take place on our mailing list: <https://lists.centos.org/hyperkitty/list/virt@lists.centos.org/> If a meeting is needed for a specific topic, members can request one through the mailing list, and we will organize it as necessary. We appreciate your participation and look forward to engaging discussions online. Best, -- Sandro Bonazzola CentOS Virtualization Special Interest Group

Proposing to drop CentOS Virt SIG meeting
by Sandro Bonazzola 05 Feb '25

05 Feb '25

Hi, I have nothing on my side for today's meeting and I won't be able to attend due to a conflicting meeting. As recently it's practically a 2 minutes meeting where I do the roll-call, nobody replies and I just drop the few updates when I have them, I'd like to propose to just cancel the recurring meeting and move whatever needs to be discussed to mailing list threads on https://lists.centos.org/hyperkitty/list/virt@lists.centos.org/ Any thoughts? If there are no objections by February 9th 2025 I would start pushing updates as needed to align with this decision on Monday February 10th 2025.
