You can always reconfigure this to the primary one. We share it in other setups as well. > So from some reason, under QEMU something is not in place, but what can > that be? It would be convenient from our perspective, if it would work... I fully agree, and I'm waiting for official EL2 support in QEMU in order to introduce a virtual target for ARM[64], just like we have on x86 already. I suppose you are using Xilinx' version of QEMU, not upstream, correct? I didn't track recently what the state of upstream is. Just checking the list again, seeing some interesting patches from early this year... Peter, can you comment on what is still missing? I'm reading that you successfully booted KVM inside QEMU. Seems like we are pretty close now and it could make sense to debug the remaining issues.
