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?

Enabling back kvm host feature for ppc64le (proposal to join the SIG)
by Fabian Arrotin 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]
