Re: [libvirt-users] Limitations of macvtap devices?

I am running OpenStack inside a libvirt guest that is connected to the local network via a macvtap interface. My experience so far suggests that a macvtap interface will not pass traffic with a source MAC address other than the MAC address of the interface itself...for example, if inside the guest eth0 is attached to a bridge. Is that correct, or is there some setting that will make that work? Outbound traffic doesn't seem to be a problem (I can see, for example, dhcp requests on the local network), but replies get dropped before they reach the guest. Thanks,
