After restarted libvirtd service, live migration VM hit an issue 'Target CPU check default does not match source none'
8:31 a.m.
Hi All,
After restarted the libvirtd service on the source host, we start live migration VM to
destination host and often hit an issue 'unsupported configuration: Target CPU check
default does not match source none’
We don’t configure any special setting for CPU model when start VM and I think it should
be ‘custom’ mode by default . Furthermore , those two hosts for doing live migration have
almost the same capabilities as below.
It’s confused me why failed to check the cpu configuration after restart libvitd service
on source host?
The libvirt version is 7.9.0, package: 1.el8 (Unknown, 2021-11-28-22:35:11) private build
Host OS version : rhat8.4
QEMU version: QEMU 5.1 private build
Any comments are appreciated.
Thanks

Please provides the guest CPU XML, the CPU model of the src and the dst
hosts:
# virsh dumpxml YOUR_VM --inactive|xmllint --xpath //cpu -
(VM is live)
# virsh dumpxml YOUR_VM |xmllint --xpath //cpu -
# virsh capabilities|xmllint --xpath //cpu -

Thanks Han for your quick response.
1. Virsh dumpxml VM from source host machine.

2, Attachments are the CPU capability information from both source and destination host
machine.

Next time, please, paste text as text rather than attaching a screenshot
of a terminal with the text. The output of dumpxml --inactive looks
suspicious as it wouldn't normally have check='full' in it unless it was
explicitly mentioned in the XML when the domain was defined.
Anyway, you did not mention how exactly you are migrating your domain,
i.e., the exact command and its parameters. The error message looks like
you're passing a custom XML to the migration command, is that the case?
If so, how does the XML looks like and how did you create it?
