ERROR:../tests/qtest/libqos/virtio.c:224: qvirtio_wait_used_elem: assertion failed (got_desc_idx == desc_idx): (50331648 == 0) I noticed it worked when I set up MSI and I further reduced the code to a simple guest_alloc() that removes the error. At the moment I am not able to identify where ths issue is and this blocks the whole pci/aarch64 enablement.
