I did a quick test with Xen's QEMU, currently at

commit 1c514a7734b7f98625a0d18d5e8ee7581f26e50c
Merge: 79c097d 35bdc13
Author: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>
Date:   Tue Jun 25 11:34:24 2013 +0000

    Merge remote branch 'perard/cpu-hotplug-port-v2' into xen-staging-master-7

from git://xenbits.xen.org/qemu-upstream-unstable.git

My guest is Squeeze with stock kernel 2.6.32.

vif=['model=virtio-net-pci,bridge=xenbr0']

No pci=nomsi in guest kernel command line.

Everything worked fine. And /proc/interrupts shows that it's indeed
using MSI for virtio PCI.

I'm kind of confused. (And in the long run of this thread I probably
didn't remember everything.)

Wei.
