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,
