Vhost-vsock: unable to set guest cid: Address already in use

I created new VM and it work fine but after install apache2
I exit from it then i wrote lxc restart vm01
after that i get error message (i don’t remember it)

lxc start vm01:

NOTICE: only vm01 have issue and other virtual machines work fine

This suggests that you have another qemu instance running for that VM.
Did you check ps aux | grep qemu for a leftover process of some kind?

it fixed after restart
but when i stop and start vm multi times
LXD freeze and don’t response

i cannot stop ,start, list or launch VMs/Containers
