Public bug reported:

When the live migration, currently we would check whether the destination host has enough memory,but would not check whether the destination host has enough vcpus.
This may lead to excessive VMs are migrated to a host, at the same time it leads to performance degradation of a VM in that host(such as io/vnc).
