ifup throws an error message, but still exit with code 0, so it should
be safe. udev and network-interface service will kick in to
automatically activate it when the interface becomes available (i.e.
when the container is started)

# ifup -a;echo $?
Cannot find device "v-c1-0"
Failed to bring up v-c1-0.
0

# ifup v-c1-0;echo $?
Cannot find device "v-c1-0"
Failed to bring up v-c1-0.
