Solarflare would be interested in the ability to pass MSI-X interrupts
through to different guests for our netfront/netback accelerator
plugins. Our latest chips support MSI-X with multiple queues so they
do not need to use multi-message MSIs. I don't know enough about VT-d
interrupt remapping to comment on that.
Cheers, Neil.
