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 qemu:///system [root@compute-0 /]# virsh -c qemu:///system list --all Id Name State -------------------- [root@compute-0 /]# virsh -c qemu:///session list --all Id Name State -------------------- [root@compute-0 /] Thanks and Regards Yatin Karel On Fri, Aug 25, 2023 at 11:52 AM Swogat Pradhan <swogatpradhan22@gmail.com> wrote:

Hi All, In this particular case, we don't need to login to any containers. To use virsh utility on the compute node we can simply install libvirt-client and execute the command as such: [root@overcloud-novacompute-1 ~]# virsh -c qemu:///system list Id Name State ----------------------------------- 1 instance-00000143 running 5 instance-0000019d running 8 instance-0000032d running 10 instance-00000160 running 22 instance-000003d4 running 30 instance-000004b0 running 32 instance-0000015c running 37 instance-0000053e running 41 instance-000009f4 running 47 instance-00000e97 running 54 instance-00000e9b running [root@overcloud-novacompute-1 ~]# With regards, Swogat Pradhan On Fri, Aug 25, 2023 at 1:07 PM Swogat Pradhan <swogatpradhan22@gmail.com> wrote:
