Does virtio say it has a write cache or not (and how does one say it?)?
Historically it didn't and the only safe way to use virtio was in
cache=writethrough mode.
Which should be the default on Ubuntu's kvm that this report is
concerned with so I'm a bit confused.
Avi's patch is a performance optimization, not a correctness issue?
