Not much on this particular box. 20 registered clients, all behind NAT 
and from all over the US. Average of about 5 concurrent calls. Host is 
an Opteron 6100 series 8 core w/16 GB RAM running Ubuntu 10.04, guest 
has 4 GB RAM and exclusive access to 2 cores on the host.

I figured the issue was KVM because the same setup on the same hardware 
configuration with an LXC guest is handles a testing load of similar 
proportions without issue. Everything here is moving to LXC over the 
next three months anyway.

My observations with KVM must be considered under the premise that I 
have not identified any specific cause for the issues related to KVM. 
Also I have not run Freeswitch on Ubuntu 10.04 on bare metal.
