2.6.31 pvops dom0 doesn't require the new IOAPIC related hypercalls.

2.6.32 and newer pvops dom0 kernels require the new IOAPIC hypercalls from Xen.
Xen 4.0.0 was the first one to introduce that hypercall.

Some of the patches related to it are backported to Xen 3.4.3, but not all.

Based on the various discussion on xen-devel it seems Xen 3.4.3 + 2.6.32 pvops 
dom0
works for some, and doesn't for others.

It's recommended to use Xen 4.0.0 + 2.6.32 pvops dom0, since that's the 
supported
and recommended configuration.
