Description of problem:
Have two host with different CPU flags, and cluster policy set to None(include all filters and also CPU-level), migration vm from host with high CPU to low CPU failed with libvirt error:
libvirtError: unsupported configuration: guest and host CPU are not compatible: Host CPU does not provide required features: est.

Version-Release number of selected component (if applicable):
is31

How reproducible:
Always

Steps to Reproduce:
1. Add two hosts with different CPU's, hosts with higher CPU host_high, host with lower host_low
2. Set cluster policy to None, also "Cluster CPU type" set to Intel Conroe Family.
3. Set vm "Allow manual migration only" and check "Use Host CPU"
4. Run vm on host_high and migrate it without specify destination host

Actual results:
Migration Failed and in vdsm log appear libvirt error.

Expected results:
Migration Failed because it not available VDS for migration with error message in engine, because host_low must be filter with CPU-Level filter, and without libvirt error in vdsm.log
