RAW_NAME="jammy-server-cloudimg-arm64.raw"

if [ ! -e "${RAW_NAME}" ]
then
	qemu-img convert -p -f qcow2 -O raw "${QCOW2_NAME}" "${RAW_NAME}"
fi

if [ ! -d "rust-hypervisor-firmware" ]
then
	git clone https://github.com/cloud-hypervisor/rust-hypervisor-firmware.git
fi

FIRMWARE_PATH="rust-hypervisor-firmware/target/aarch64-unknown-none/release/hypervisor-fw"

if [ ! -e "${FIRMWARE_PATH}" ]
then
	pushd rust-hypervisor-firmware
	cargo build --release --target aarch64-unknown-none.json -Zbuild-std=core,alloc -Zbuild-std-features=compiler-builtins-mem
	popd

cloud-hypervisor --serial tty --console pty --kernel "${FIRMWARE_PATH}" --disk path="${RAW_NAME}"

Expected output

The VM boots and shows ubuntu login: .
