[libvirt] flaky network on clients/guests machines - please help!

I've set up a redhat ( Linux 2.6.18-194.8.1.el5 #1 SMP Wed Jun 23
10:52:51 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux) box and two virtual
hosts (clients/guests). The network on the host is fine, however the
clients network is extremely flaky....Sometimes it connects into and
out of the client, but sometimes it gives me all sorts of timeout, no
route, etc messages....I've tried everything I can think of, turning
on dnsmasq, nscd, and adding options single-request in resolv.conf,
but nothing seems to work. The client machines are running the same
os as the host....Please see below results of running strace on ssh to
another machine....(I can ssh to this other machine from the host and
from any other machine and at times from the clients)...Any help will
be greatly appreciated.....
[root at testbedwww ~]# strace ssh phys.lsu.edu
