Add hypervisor CPU feature check during live migration

Registered by chengsheng on 2020-11-09

When the vm does not specify a host for live migration, it will call libvirt's compareCPU() to compare cpu features, which is not very useful. For example, when the kernel version of the host is different, compareCPU() passes the check, but in fact the cpu features of the host may be different, When the vm is live migrated to this host, a startup error will occur.

In order to solve this problem, add hypervisor CPU feature check during live migration.
