It is not so much a shortage of VT-x capable laptops in general but
rather a shortage of ones available for us to test with.
Thanks

I'm obviously missing something obvious here. I wasn't able to easily
find out what `CMBattery' is (perhaps I need to read a suitable volume
of ACPI spec) but laptops have been having ACPI-based battery
management for quite a while.
You mention a shortage of VT-x enabled laptops but a quick websearch
suggests there are plenty of AMD-V-capable laptops.
Dare I ask, what about PV guests ? Obviously access to the host
battery is not supported for right now but what is the plan ?
Sorry if these seem like stupid questions.
Ian.
