Thanks in advance. Hi Kaushal, if you read carefully what I replied above, I believe my answer addresses what you've been experiencing. I'd advise the following to address your needs: - use a preseed installation config where you install the SSH server in the VM in an automated fashion - use static IP allocation in libvirt's network XML for that specific machine => see https://libvirt.org/formatnetwork.html#elementsAddress - depending on the actual use case I'd also recommend considering usage of the libvirt-NSS plugin which conveniently alleviates the need to know the IP of the VM => see https://libvirt.org/nss.html Regards, Erik
