[Qemu-discuss] any restriction on the guest mac addr when using tap networking?
Sun, 28 Apr 2013 05:49:29 +0000
when using tap networking, everything works perfectly when i don't specify a
specific mac addr for the guest, but when i choose a mac addr for the
guest(just 6 random bytes), strange things happen. sometimes it works,
sometimes it don't.
when i dump the traffic on the tap device, the host obviously could receive
the packets sent by the guest because it answers all the arp requests, but the
guest seems couldn't receive anything at all as it still send arp request and
the packets it received is zero from the status of the connection(it's running
so i guess there's some limitation about the mac addr i could assign to the
guest? i googled but didn't find anything related.
p.s. the host is running linux 3.9.0-rc6+ and qemu-1.4.1
