My word may be a little bit confusing, it should be
I also perform an additional test: I created two qemu guests (macvtap bridge mode on eth0), they CAN communicate each other no matter network cable of the host is unplugged or not.
and my problem is specified in the subject already: guest/host cannot communicate when network cable is unplugged
if my configuration seems correct, i may file a kernel bugzilla and seek for their advice.
