I experience a similar issue with libvirt 1.2.20 on ubuntu 15.04 (3.19.0-30-generic #34-Ubuntu x86_64)

If I use "Copy host CPU configuration", virt-manager ends up using a Westmere profile instead of Haswell (i7 4700MQ)- more details here: https://bugzilla.redhat.com/show_bug.cgi?id=1271157

If I use "Haswell" profile, I get the following error:
Error starting domain: unsupported configuration: guest and host CPU are not compatible: Host CPU does not provide required features: rtm, hle, x2apic; try using 'Haswell-noTSX' CPU model

If I use "Haswell-noTSX" profile, I get the following error:
Error starting domain: unsupported configuration: guest and host CPU are not compatible: Host CPU does not provide required features: x2apic
