Besides modules.img problem, this wouldn't work with virt_mode pvh, because pvgrub2 does not support pvh yet. There are some patches for that in RFC stage, so this may change in the future.

It should work with virt_mode pv though, right?

Yes (besides that modules.img bug). You can try by creating empty modules.img file.

Additionally, templates for R4.0 comes with grub preinstalled, which can be used in HVM mode:

qvm-prefs vmname virt_mode hvm
qvm-prefs vmname kernel ''

Nice, that cuts out the pain of having to manually install grub, etc. like on R3.2.
