The IP does no longer respond to a remote ping

With restart I mean:

lxc-stop -n vm3
lxc-start -n vm3 -f /etc/lxc/vm3.conf -d

You're writing about Linux containers (LXC). You have the ability to assign a static IP address in the container's configuration file. Here's an example from my environment:

lxc.utsname = MPG_Web
lxc.tty = 4
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.mtu = 1500
lxc.network.ipv4 = 172.16.16.110
lxc.network.hwaddr = 00:30:6E:08:EC:80
lxc.rootfs = /srv/lxc/MPG_Web
lxc.mount = /etc/lxc/MPG_Web.fstab

You seem to be missing the lxc.network.ipv4 directive in your setup.

Unfortunately, you will need to use a script to inject your default and static routes. This isn't controllable from the LXC configuration file (yet).
