While it might be normal to disable PSCI on KVM, I doubt the
VFP helpers are correct ;)
Anyway this allow to link the binary and run a KVM guest.
Tested using:
$ make pc-bios/edk2-aarch64-code.fd
$ dd if=/dev/zero of=flash1.img bs=1M count=64
$ aarch64-softmmu/qemu-system-aarch64 \
-nographic \
-enable-kvm \
-M virt,gic-version=3 \
-cpu host \
\
-pflash pc-bios/edk2-aarch64-code.fd \
-pflash flash1.img \
-drive if=none,file=bionic-server-cloudimg-arm64.img,id=hd0 \
-device virtio-blk-device,drive=hd0 \
\
-netdev type=user,id=net0 \
-device virtio-net-device,netdev=net0
