Steps to reproduce: 1. start the VM with qemu64 on the CPU: Intel(R) Xeon(R) CPU E5-2620 v4 2. live-migrate the VM to a CPU: Intel(R) Xeon(R) CPU E5-2670 0 Additional information: The migration fails: ``` root@covid21:~# virsh migrate --verbose --live --persistent --undefinesource myvm.local qemu+ssh://covid24/system error: operation failed: guest CPU doesn't match specification: missing features: abm ``` This should not happen on a generic CPU, which should always work. Note, that the migration succeeds when using `-cpu qemu64,abm=off …`
