Description Adam Williamson 2017-07-05 19:07:56 UTC
virtManager/config.py has this little stanza in `get_default_cpu_setting`, the method for returning the 'default' CPU model:

        if for_cpu and ret == CPU.SPECIAL_MODE_HOST_MODEL:
            # host-model has known issues, so use our 'copy cpu'
            # behavior until host-model does what we need
            ret = CPU.SPECIAL_MODE_HOST_COPY

I believe the 'known issues' referred to there are those documented in https://bugzilla.redhat.com/show_bug.cgi?id=870071 , which is closed from libvirt 3.2.0 onwards.

Perhaps this workaround should now be removed, or made conditional on libvirt < 3.2.0, at this point?

Note: I'll be opening a similar issue on Boxes, which acts similarly.
