Does the domU freeze?
Does you DomU have it's root filesystem mounted via nfs?
Please make sure that you can ping any sizes of packages from the domU to your 
nfs server. You may need to set package sizes used by nfs down to a low value 
e.g. 1024 to make sure al packages are so small that you don't need IP 
fragmentation. Maybe you will need to lower you MTU of the eth0 interface 
inside the domU.
If you domU doesn't freeze or you don't use rootfs over nfs, then you probably 
need to look elsewhere for the source of your problems.
