OVMF can only use PXE/network boot when a virtual RNG device is added
for VMs, but this is not obvious from the UI or the error behavior.
Add a small warning to the boot order edit that says what is necessary.

Style nit: no need for the if block. You can assign the expression directly.

Nit: No need for toLowerCase() and includes(), it can just be === 'ovmf'
like we already do in other places?

Nit: maybe use active voice?
For PXE boot with OVMF, you must add a VirtIO RNG device!
