KVM planes branches

Hi everyone,
happy new year!

I am curious about the state of the KVM planes effort and want
to experiment with it a bit.
I tried out the KVM planes branches we have in our GitHub org.
I built Qemu and the host kernel from there and I am able to launch
the current SVSM with that. QEMU just needed the patch for MADT-via-IGVM.
But the OVMF does not seem to start. All I see is

...
[SVSM] VTPM: TPM 2.0 Reference Implementation initialized
[SVSM] [CPU 0] Virtual memory pages used: 0 * 4K, 0 * 2M
[SVSM] VMSA PA: 0x8000f49000
[SVSM] Launching Firmware
[init] COCONUT-SVSM init process starting
[SVSM] Terminating task init, exit_code 0
[SVSM] Launching request-processing task on CPU 1
[SVSM] Launching request-processing task on CPU 2
[SVSM] Launching request-processing task on CPU 0
[SVSM] Launching request-processing task on CPU 3

and then it seems to hang forever.
Is that expected? Do I need a specific commit of SVSM or EDK2?

Any hints are very welcome!

Cheers,
 Oliver
