Wow great job digging through all these hypervisors!
There is more ... :(

It uses the incremental vq index assignment like QEMU.
impl VirtioMio for Balloon {
fn activate<'a, 'm, Q: VirtQueue<'m>, S: IrqSender>(
&mut self,
feature: u64,
_active_mio: &mut ActiveMio<'a, 'm, Q, S>,
) -> Result<()> {
let feature = BalloonFeature::from_bits_retain(feature);
self.queues[0] = BalloonQueue::Inflate;
self.queues[1] = BalloonQueue::Deflate;
let mut index = 2;
if feature.contains(BalloonFeature::STATS_VQ) {
self.queues[index] = BalloonQueue::Stats;
index += 1;
}
if feature.contains(BalloonFeature::FREE_PAGE_HINT) {
self.queues[index] = BalloonQueue::FreePage;
index += 1;
}
if feature.contains(BalloonFeature::PAGE_REPORTING) {
self.queues[index] = BalloonQueue::Reporting;
}
Ok(())
}
I'll dig some more, but this is getting out of hand :D
