[Fedora-xen] Network issues with F11 guests

[Orion Poplawski]

Has anyone experienced network trouble with F11 xen paravirt guests? 
I'm running centos 5.2 with a newer virttest kernel.  During anaconda 
install it seems like it just gives up trying to download packages.  Hit 
"retry" and on it goes.

Seems like it may be IPv6/DNS/arp related.  Last traffic I see from the 
guest is a DNS request followed by an arp request:
