[libvirt] Cannot get network to work with LXC

Hi all, I tried to use the first xml config in http://libvirt.org/drvlxc.html to setup my first light weight container. However, I was unable to get the container's network to work. When I tried to give the interface an IP, I got the following error message: sh-4.0# /sbin/ifconfig veth1 192.168.0.1/24 SIOCSIFADDR: Permission denied SIOCSIFNETMASK: Permission denied SIOCGIFADDR: Cannot assign requested address SIOCSIFBROADCAST: Permission denied SIOCSIFFLAGS: Permission denied sh-4.0# Any advise ?
