This post is about booting guest using qemu-kvm.

Guest Image

Like create domU on xen, you still need to prepare a guest image including guest kernel, bios image.

For qemu image on arm64, you can download it from official site:

1 2	wget https://releases.linaro.org/components/kernel/uefi-linaro/15.12/release/qemu64/QEMU_EFI.fd wget https://releases.linaro.org/components/kernel/uefi-linaro/15.12/release/qemu64/QEMU_EFI.img.gz

Build Qemu

Get qemu from source on hikey960 (I recommend to compile on board directly if you dont want to handle those annoying libs

1	git clone http://git.qemu.org/git/qemu.git

If your guest is downloaded from above link, set target as aarch64-softmmu is enough. Config qemu and compile it:

# ./configure --target-list="aarch64-softmmu aarch64-linux-user" 
./configure --target-list="aarch64-softmmu" 
make
make install

Run Guest

taskset -c 0-3 qemu-system-aarch64 -m 1024 -M virt -cpu cortex-a53 -smp 4 -bios "/path/to/QEMU_EFI.fd" -nographic -device virtio-blk-device,drive=image -drive if=none,id=image,file="/path/to/QEMU_EFI.img.gz" -enable-kvm

Currently, Cortex-A73 is not supported by qemu, we have to pin vcpus on cortex-a53 via taskset -c 0-3 (cpu 0 - 3 are all cortex-a53)

I dont have a screen to show results, that’s why -nographic is needed.

-enable-kvm to let qemu make use of kvm to boost guest.

Now you should boot guest successfully.
