[Bug 2060020] Re: [Ubuntu-24.04]: Unable to bring up a guest with 1GB RAM using virt-install

[Bug 2060020] Re: [Ubuntu-24.04]: Unable to bring up a guest with 1GB RAM using virt-install
FYI Yeah, the problem is that - as so often - "it depends". There are installations which easily work with 1GB like an x86 KVM with not many devices. On the other hand this isn't listed as "minimum", but as "recommendation" and that could indeed be higher to tolerate more install environment variations at the memory size that is stated as "recommended". The 3GB mentioned here comes from osinfo-db which also has to include e.g. Desktop environments. Thanks Jbicha for providing that in the first place. Let us align what osinfo says here with the docs: - 3GB https://github.com/crobinso/osinfo-db/commit/1de8347e88f8b52849c11da9d0f154663220033d - 1GB https://discourse.ubuntu.com/t/basic-installation/11320 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060020 Title: [Ubuntu-24.04]: Unable to bring up a guest with 1GB RAM using virt- install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/2060020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Oh sorry, I just noticed that the ppc64el ISO was NOT updated and is still from March 28th, means it still has the -11 kernel inside. We need to investigate why it wasn't updated - and why there is no daily from April 1st and 2nd ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060020 Title: [Ubuntu-24.04]: Unable to bring up a guest with 1GB RAM using virt- install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/2060020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello Kowshik, thanks for bringing this up. 2GB RAM is not a lot, but according to 22.04 it should be sufficient (for Ubuntu Server, Ubuntu Desktop already wants 4GB) - so I am not sure if the min. req. for RAM may have or will change with 24.04 - I'll check. Meanwhile, would you please re-try with the latest daily ISO image from today: https://cdimage.ubuntu.com/ubuntu-server/daily-live/current/noble-live-server-ppc64el.iso since it has an updated kernel included (and afaik an updated installer). If the problem still persists, would you please also attach the crash files (from /var/crash). And do I interpret it correctly that this only happens with virt-install using 1GB RAM, or also in other scenarios where the system has just 1GB RAM (like a 1GB LPAR, or using virsh instead of virt-install with a KVM guest definition of 1GB). I would like to understand if this is related to / or limited to virt-install or not. ** Package changed: libvirt (Ubuntu) => virtinst (Ubuntu) ** Also affects: ubuntu-power-systems Importance: Undecided Status: New ** Changed in: ubuntu-power-systems Assignee: (unassigned) => Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) ** Changed in: virtinst (Ubuntu) Assignee: Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) => (unassigned) ** Changed in: ubuntu-power-systems Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060020 Title: [Ubuntu-24.04]: Unable to bring up a guest with 1GB RAM using virt- install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/2060020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
