[Xen-users] Xen RTNETLINK answers: Device or resource busy

[asim hafeez <asim.mcp@xxxxxxxxx>]

I'm getting following error while creating vm. here is network interface config.

vif = ['type=ioemu, ip=192.168.122.101, vifname=vifvm102.0, mac=00:16:3e:f1:51:45, rate=12800KB/s, bridge=br0']

If i replace it to following then it works fine.

vif = ['type=ioemu, rate=12800KB/s, bridge=br0']

here are logs

bridge=br0
'[' -z br0 ']'
RET=0
ip link show br0
