I noticed that KVM is setting paravirt_enabled = 1 twice, once the
main kvm guest code and once in kvmclock.

Will the EBDA code in head.c care?

That would also increase sanity a little IMO.  We currently have
"paravirt" meaning that the normal HW architecture isn't present (Den,
lguest) and "paravirt" meaning that there are extra optional-to-use
hypervisor features (KVM, etc).
