Summary: Quiet erroneous stopVM failures on kvm
Detail: Cloudstack tries to stop VMs all the time, for all sorts of reasons,
but usually just to get into a known state. Libvirt throws an exception of
'Domain not found' when attempting to stop a VM that doesn't exist. This causes
problems for troubleshooting real issues. Domain not found should equate
to success if trying to stop.

> Components: KVM, Storage Controller
> Affects Versions: 4.2.0

> While deploying the instance in KVM,
> its checking whether the dom is already present or not by searching the dom
> and trying to stop it.
> As the dom is not present, its throwing the below exception and deploy is
> failing.
> I guess it good to check if the dom is present by lookup and continue further
> instead of stopping a dom which is not present which will definitely throw an
> exception and deploy fails
