But it breaks live migration, probably when the source host runs an 
older kernel.

When libvirt tries to complete the migration, it aborts with:
error: Domain not found: no domain with matching name 'VMNAME'

On the destination host, in /var/log/libvirt/qemu/VMNAME.log:
kvm: Features 0x300fffe3 unsupported. Allowed features: 0x711fbbe3
qemu: warning: error while loading state for instance 0x0 of device 
'0000:00:03.0/virtio-net'
load of migration failed

I tried again with the older 3.2.60-1+deb7u3 on the destination host, 
this works fine.

Cheers
