Is 64-bit domU support available anywhere at the moment? For example,
what is the status of the git://git.et.redhat.com/xen-pvops-64.git
tree?  I pulled that tree and tried building 64-bit Xen domU support
(since this tree allows you to configure the kernel with that
capability, unlike the vanilla Linux tree). But compilation failed in
enlighten.c because xen_smp_ops isn't defined in x86_64.

Try building without CONFIG_SMP, it doesn't support that yet.

Other than SMP support, does the tree represent a fully functional 64- bit PV domU support? Does it also allow all hypercalls? Put another way: is a 64-bit PV domU from that tree less capable than a 64-bit PV domU from Xen's linux- tree?

Redhat have some patches which they're shipping in Fedora 9. Once F9 is out the door, I'm hoping they'll polish them into an upstreamable form. I don't know whether that git tree represents what's in F9, or if that's somewhere else; at the very least I'd expect you'd be able to pull the
patches out of the srpm.

Yep, this tree:


is the work-in-progress x86_64 tree.

This tree:


is what we're actually shipping for F-9. It includes the x86_64 work,
but some other paravirt_ops patches too, most of which are queued up

Which tree do you recommend I use?
