[PATCH manager v2] ui: qemu: boot order: warn of missing pxe support for ovmf

[Dominik Csapak]

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.
