Im experiencing a strange issue which I can only reproduce with qemu -current (git clone from today) on aarch64 Linux with KVM enabled kernel (MANJARO Linux 5.4.0-2-MANJARO) running on the Pinebook-pro (arm64)
When trying to boot the miniroot66.fs from OpenBSD I get the following failures for these configurations
/usr/local/bin/qemu-system-aarch64 \
-M virt \
-m 512 \
-cpu cortex-a57 \
-bios QEMU_EFI.fd \
-drive file=miniroot65.fs,format=raw,id=drive1 \
-drive file=obsd-arm64.qcow2,if=none,id=drive0,format=qcow2 \
-device virtio-blk-device,drive=drive0 \
-nographic \
-serial tcp::4450,server,telnet,wait
As well as with KVM enabled a
/usr/local/bin/qemu-system-aarch64 \
-cpu host -M virt,accel=kvm -smp 2 \
-m 512 -nographic \
-bios QEMU_EFI.fd \
-drive file=miniroot66.fs,format=raw,id=drive1 \
-drive file=disk.img,if=none,id=drive0,format=qcow2 \
-device virtio-blk-device,drive=drive0 \
-net nic -net tap
celeration
In both cases I get the following error during boot
BdsDxe: failed to load Boot0001 "UEFI Misc Device" from VenHw(93E34C7E-B50E-11DF-9223-2443DFD72085,00): Not Found

Again this only happens on aarch64 system, everything works as expected on x86_64
Linux. Also I can boot with no problems on aarch64 via qemu-system-aarch64 (KVM)
NetBSD, FreeBSD, RHEL8, Centos8, Ubuntu18.10
