Is there a way to find out the Static IP address if the KVM Guest VM
instance is shut off? Thanks in advance.
Maybe?
In the case of --source agent, the guest must be queried, and the guest
is no longer running so it can't answer. In the other cases, libvirt is
looking for the name of the tap device used by the guest interface, but
the tap device no longer exists. So libvirt doesn't provide any method.
However, if the guest was recently running, there may still be an entry
left in the arp cache, and you would be able to see it by grepping (on
the host, of course) for the guest's MAC address, like this:
arp -an | grep 52:14:00:74:11:14
That's not going to work if the guest has been down for longer than the
timeout of the arp cache though (or if the guest hasn't communicated
with the host in any manner for that amount of time).
