Hi! When adding VETH interfaces to containers with the following command:
vzct set CTID --netif_add eth0,,,,vzbr0 --save an automatically generated MAC address of the format 00:18:51:XX:XX:XX is configured for the container. This can cause problems with bridges, since bridges seem to use the MAC address of the member with the lowest MAC address. So if I start said container on the hostnode, and the hostnode's physical NIC has a MAC 00:30:48:XX:XX:XX, the MAC of vzbr0 switches from 00:30:48:XX:XX:XX to 00:18:51:XX:XX:XX (and vice versa when stopping said CT). This MAC address switching causes network lags for all members of the bridge vzbr0. Of course, I can manually change the configured MAC address in each CT's ctid.conf (which I did in the past), but I wonder if there is a way to configure the range of the auto-generated MAC addresses.
