Thanks for the patch, great work.
Only one question is that: why just merge gpt into 'vm' rather than
create an new 'block-device-gpt' element?
We then just need to add some partition configuration file into 'vm'
element, like the one you add in test case:

I think qemu image just need to install grub into /EFI/BOOT/. We can
make it by adding '--removable' option when installing the grub.
