Hi Swogat,

Yes the commands are correct, snippet from local system:-
[root@compute-0 ~]# podman exec -it nova_virtqemud /bin/bash
[root@compute-0 /]# virsh list --all
 Id   Name   State
--------------------

[root@compute-0 /]# virsh uri

[root@compute-0 /]# virsh -c qemu:///system list --all

[root@compute-0 /]# virsh -c qemu:///session list --all

[root@compute-0 /]

Thanks and Regards

Hi Swogat

You can use the virsh commands from "nova_virtqemud" container in stable/wallaby+.

Thanks and Regards

Hi,
Can someone please tell me how can i access the virsh utility on the compute node on openstack wallaby?

Previously we used nova_libvirt but in wallaby there are multiple containers and i am unable to use virsh utility to edit my domain.xml file.

List of containers:
