Do you observe the same behavior after setting this for the VM ?
xe vm-param-add uuid=$UUID param-name=platform tsc_mode=2
xe vm-param-add uuid=$UUID param-name=platform nomigrate=true
(beware you lose live migration support doing this, you can cancel these changes with matching vm-param-remove like xe vm-param-remove uuid=$UUID param-name=platform param-key=nomigrate)
@MajorP93 can you give the kernel version of all the affected vs non-affected guests ?
@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.
@acebmxer which kernel version you have in your Debian guest (uname -a) ?
Can reproduce on Fedora 44 and Alpine Linux (6.18.22-0-virt).
But doesn't occur on Debian 13 (6.12).
@poddingue FWIW I've seen the same on FC44 as well, but I don't yet know where it came from.
