Here's a draft MSI-X support patch. Among missing features: save/load support, and command-line flag to control the feature. This is on top of qemu-kvm: msi-x is disabled without kvm interrupt injection support for now.
What's your impression of how much work would be to get this going on top of upstream QEMU?
I'm willing to borrow a few cycles to help out here. I'd really like to see this series go in via QEMU if possible.
