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
