Thanks.  I've now found that this is explicitly stated in the 5.2
x86_64 release notes.  It would be good if this information made it
into the Virtualization guide, though.

I won't be doing any save/restore/migrate on these guests, and I am
keen to use paravirtualisation for performance, and, more importantly,
ease and speed of (re)deployment.
