[libvirt-users] Libvirt mpiexec networking issue

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.
