Thanks. Is this supposed to work in 2.6.32 ? It didn't work for me.

I tried these :

ip link add link eth0 name myvmnet address 00:aa:bb:cc:dd:ee type
macvlan mode bridge
ifconfig myvmnet gwaddr up

and then in my lxc config

lxc.network.type = macvlan
lxc.network.macvlan.mode = bridge
lxc.network.link = myvmnet
lxc.network.ipv4 = x.y.z.p/24
lxc.network.name = eth0
lxc.network.flags = up
lxc.network.mtu = 1500

I still can't ping the gwaddr from container. Also after a while my
host hung as my root is at a nfs location. Not sure if these are
related.
