I'm using Xen 3.4 with Fedora 7 for both Dom0 and DomU. If I try to
configure more than 3 vifs, I only get eth0, eth1, and eth2 in DomU.
An error message also prints during the boot process: ####netfront
can't alloc rx grant refs

I was under the impression that this was fixed a while ago (according
to the FAQs, Xen 3.1 had a limit of 8 vifs). Googling the error
message said the same thing, that this was a limitation for only Xen
3.0 and earlier. Does anyone know if I'm doing something wrong?

vif config:
vif = [ 'bridge=br0', 'bridge=br0', 'bridge=br0', 'bridge=br0' ]
