[SOLVED] Automatically setting MTU for newly created containers

[MatthiasMerkel]

In our configuration we use a MTU of 1462 on our LXC containers because of tunneling. We currently do this by manually adding the mtu option to the config file of every newly created LXC container.

Is it possible to make Proxmox automatically add the MTU option to the network interface when a new LXC container is created?

EDIT:

Solved by adding the line

lxc.net.0.mtu = 1462

at the end of /usr/share/lxc/config/common.conf

Thanks for posting your solution! Saved me a major headache!

I think the proposed solution will not work on a cluster environment, at least will not be efficient modify the file on all the PVEs...

Is there other alternative? May be something on the pmxcfs?
