Thanks for the insight. I had not thought about the firewall specifically as yet, but you reminded me, that we have to take that into account as well. :) I would like to avoid if possible tweaking the XML, only for the sake of not having to touch our scripts if the XML structure/format changes significantly, but that may be the best way, all things considered.

The only immediate thing I can think of is the firewall rules the libvirtd adds. You'd want to check that libvirtd is (or is not?) creating the right rules for you. Also note that if you restart the firewall, all the libvirtd rules get thrown out and your guests can't talk to each other (RHBZ#227011). > Same basic question for mount points to shared storage between KVM > hosts.

If you want precise control over how guests are created, use virt-install or even create/edit libvirt XML directly from your scripts.
