Thanks for all your suggestion. Just a check, if i have a full backup on the server but due to the different specs of the hardware so i am unable to do a bare metal restore, can i just dump all the folders under /var/lib/libvirt which also includes the images folder? Will it work that way?
Here is the folders in libvirt:
[root@pop-kvm-web libvirt]# ls
boot images iptables network qemu
Thanks!

If you do it often, you might consider listening for ssh connections on
a separate port and using tc to keep things from getting out of hand:
