Change mtu without turning off vm

[shahin352]

Hello

I have number of vms that I need to change the MTU value without turning them off. When I try to do this from the webui side of the vms, the network card is disconnected and the vms need to be turned off or restart. The MTU value is not set to 1, so changing the MTU for the bridge does not make a difference.
Is there a solution for this?

What about : ip link set dev eth0 mtu 1400
