When rebooting lxc container other containers become unresponsive

hi all,

Not sure how to debug this issue. I am having the following issue. when i reboot a container other containers are unresponsive (ssh commands) until the conainer is fully rebooted.

any way to debug and resolve this?

Most likely your bridge doesn’t have a fixed MAC address, so the kernel rule of setting the MAC to match the lowest one in the bridge is applied. When the container goes down, the bridge changes MAC address, causing a few seconds delay for ARP and the like.

Set a static MAC on your bridge and you should be fine.

Are we talking the mac adress on the host? or inside the container?

The one on the host side of the veth pair connecting the container to the bridge.
