No biggie. Gave me a chance to dig more into Xen :).

I think I remember a message about SG being set to 0, but my memory is
shot. I'll try this as soon as I get home and VPN in, as my work
machine is x64, and HWVSP doesn't work w/ x64.
I did realize that I forgot to set my vif to a null array, as per the
install instructions. I had:
vif = [ 'mac=00:16:3e:50:02:f4, bridge=bridge0, type=ioemu,
model=e1000', 'mac=00:16:3e:50:02:f5, bridge=bridge1, type=ioemu,
model=e1000', 'mac=00:16:3e:50:02:f6, bridge=bridge2,
type=ioemu, model=e1000' ]
Would that cause it? If so... how would I setup the mac/bridge
information w/ a null array?
Thanks again!
