Re: [libvirt] [PATCH] lxc: fix veth off by 1 error

When not specifying a target for veth device, veth.c:getFreeVethName() is supposed to scan for unused veth devices in /sys/class/net. However, when it finds one, it bumps the index by one before returning it. So, if you have one container running, veth0 is passed into the container, veth1 is taken and still sitting in /sys/class/net. When you now start a second container, getFreeVethName() finds veth0 is unused, but returns 1. Now container creation dies becuase /sys/class/net/veth1 exists.
