@danlythemanly are you one of the original authors or did you just rescue the repo from google code?

Yes I wrote the original version, but have not worked on it in years.

Ah, that's a pity, but thanks for the original work! Do you have any pointers for what it might mean for a third party to update the patches for recent Xen and other developments? Are there other things that have happened since you stopped that might simplify or complicate this work?

Thanks!

The basic idea was to run a PV Xen installation inside an HVM guest. Since HVM Xen is supposed to support an unmodified OS, it isn't all that far off. The piece that was missing was that the devices exposed to the HVM guest were PV, and that wasn't something that Xen was able to deal with out of the box. So, most of the changes were to interface with devices. I don't know how much the paravirtualized device interfaces have changed since then.

The only other thing to consider is that hypervisor support for nested virtualization could now be available in some providers (I don't know if it is or not), which would allow you to just run another hypervisor out of the box. You can check cpuinfo on some cloud servers for vmx or equivalent to see if this is the case.

Good Luck! Dan
