I guess I should specify my current network setup. I used the default network settings and both of the VMs include the following in their XML configuration files:
<interface type='network'>
<mac address='52:54:00:2f:a5:58'/>
<source network='default'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
Also, when I do ifconfig on the guest VMs I just get an eth0 and an lo interface. (I have seen on the Libvirt networking pages something about the virbr0 interface but I'm not sure if that is what I need or how to set it up)
Thanks in advance for your help.

Hi all,Not sure if this is the best place to put this question since I'm not sure if it's a Libvirt issue but...I currently have two VMs up with networking and I can successfully ssh to and from each VM and I have confirmed that I can successfully download things from the internet. However, when trying to run mpiexec (which uses ssh), the connection fails and gives me the following errors:[proxy:0:0@guestVM] HYDU_sock_connect (./utils/sock/sock.c:188): unable to connect from "guestVM" to "guestVM" (Connection refused)[proxy:0:0@guestVM] main (./pm/pmiserv/pmip.c:205): unable to connect to server guestVM at port 56514 (check for firewalls!)Just so it is clear, I know that the two guests host names are the same (they are clones) but I am giving explicit IP address for the connection so it should not be an issue. Does any one know if there is something unique with how Libvirt networking is set up that would cause such an error? I have tried checking for firewalls and there don't seem to be any.Thanks,Shawn--Virginia Tech
