Hi,
i have several libvirt hosts servers with differents CPU generation, in
particular :
- older generation : Intel Xeon E5-2640 v4 2.40GHz
- newer generation : Intel Xeon Gold 5215 2.50GHz
i recently re-install all this servers into ubuntu server 22.04.1
and since, when i live migrate a VM from a new generation processor to older
generation processor
the migrated guest freeze without generating any error logs.
if i migrate the opposite way ( older cpu to newer cpu ) it works
perfectly.
previous version of hosts ( same hardware on ubuntu 16.04 ) did not
present the problem
the live migration is done with the following command ( issued from a
third server playing the role of 'virtual-center' ) :
virsh -c qemu+ssh://root@new_server/system migrate --verbose --live
--undefinesource --persistent --unsafe guest_name
qemu+ssh://root@old_server/system
this one freeze the guest
while the opposite migration :
virsh -c qemu+ssh://root@old_server/system migrate --verbose --live
--undefinesource --persistent --unsafe guest_name
qemu+ssh://root@new_server/system
works without problem
migrate between 2 servers with same generation CPU also works perfectly
the cpu configuration of guest is generic :
<cpu mode='custom' match='exact' check='full'>
<model fallback='forbid'>qemu64</model>
<feature policy='require' name='x2apic'/>
<feature policy='require' name='hypervisor'/>
<feature policy='require' name='lahf_lm'/>
<feature policy='disable' name='svm'/>
</cpu>
- i have tried several ( almost all ) other virtual cpu configuration ,
- always with the same problem.
