** Description changed: 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> -
