If the documentation states that this is commonly used with virtio/xen
pv drivers, then I'm afraid people will just assume that's the only
devices the platform is used with.

Any mention of specific devices or features steers the attention away
from the essential point of this documentation.

I don't see how adding this text helps.  Such documentation should go
elsewhere, in QEMU, or a Xen/KVM web page or something like that.

Anyway, I'm not religious about this point.
