      @poddingue FWIW I've seen the same on FC44 as well, but I don't yet know where it came from.

        Can reproduce on Fedora 44 and Alpine Linux (6.18.22-0-virt).
        But doesn't occur on Debian 13 (6.12).

            @acebmxer which kernel version you have in your Debian guest (uname -a) ?

              This is on fresh install Debian 13 deployed from XO Hub - 6.12.38+deb13-amd64. I do not see this behavior on Ubuntu.

              after update 6.12.90+deb13.1-amd64
              still happens.

                @acebmxer I don't observe the same issue on Debian 13 Cloud-Init (both 6.12.38+deb13-amd64 and updated 6.12.90+deb13.1-amd64).

                Though it still takes some time to boot (especially at loading the ramdisk) but it's not related to this pv spinlock issue and mostly a "BIOS guest" related issue.
                But I'm testing on a Intel machine.

                    I was going to suggest it might be a amd issue. I can try later on work host that are intel.

                      @TeddyAstie These spinlock events that cause slow boot also happen on my Debian VMs. Also AMD Epyc CPU in my case.

                      I noticed that this only happens for UEFI enabled VMs. VMs booting in BIOS mode do not have this issue.

                        @MajorP93 can you give the kernel version of all the affected vs non-affected guests ?
