i had the same problem with icehouse on ubuntu 14.04 LTS and fixed it with the following change in
/usr/lib/python2.7/dist-packages/nova/virt/libvirt/driver.py

at line 4338 ff i removed

        for f in info['features']:
            cpu.add_feature(vconfig.LibvirtConfigCPUFeature(f))

and replaced it with

        test = []
        for f in info['features']:
            if f not in test:
                test.append(f)
                cpu.add_feature(vconfig.LibvirtConfigCPUFeature(f))

maybe this helps someone until the fix is released.

Hi,

its a bug it the code. The workaround is to comment the function in the
libvirt code which checks the flags of cpu while migration. Do make sure
manually that the cpu flags of both the compute nodes are same.
