Hi experts,
When I hotplug nic into lxc, the nic in lxc seemed to be down status as
following:
1224: vnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether fa:16:3e:fc:e5:96 brd ff:ff:ff:ff:ff:ff
It seems mechanism such as udev is needed here. But I found udev is not
supported well in lxc.
So how can I get a 'up' nic after hotplug into lxc ?
Correct, there is no udev support in LXC.
In very recent versions of LXC, libvirt will let you define IP address
info in the XML and if that is present, then it will ifup the NIC
for you. If you need DHCP instead of static addressing though, there
is no easy way to address this.

Daniel
