I guess you mean EFI rather than just GPT?

FWIW virt-p2v has some support for EFI, but it's very hairy
and not that well tested.  It tries to modify the guest
to use BIOS for booting.

I'm waiting for good, free EFI support in qemu and then I
can remove such hacks.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into KVM guests.
