Re: PvGRUB2 on Arm64?
Yes in effect, that is what I want.
There seems to be a GRUB2 module which works in the opposite direction which allows launching the Xen hypervisor from GRUB, but I want to launch GRUB2 with PV drivers as the bootloader for a DomU (Ubuntu in my case). Looks like we need an equivalent arm64 relocator.S as provided for x86 in

So you are basically looking for grub2 with Xen PV drivers.
That should be doable, but it requires at least some work. The best way forward
would be to have grub2 modules for that purpose.
The code is there already, it "only" needs to be made generally available and
be activated. A good blueprint for that is the i386-xen_pvh variant of grub2.
Unfortunately I don't have time now to work on that.
