Qemu Emulation

In archlinux, install packages via:

$ sudo pacman -S qemu-arch-extra
$ yaourt cloud-utils

Create the img via following command:

root@archiso ~/arm # cloud-localds my-seed.img my-user-data 
root@archiso ~/arm # cat my-user-data 
#cloud-config
password: enginexxx
chpasswd: { expire: False }
ssh_pwauth: True
ssh_authorized_keys:
 - ssh-rsa xxxxxx
timezone: Asia/Chongqing

Download the ubuntu image files in:

# wget http://cloud-images.ubuntu.com/daily/server/xenial/20171214/xenial-server-cloudimg-arm64-uefi1.img
# wget https://releases.linaro.org/components/kernel/uefi-linaro/latest/release/qemu64/QEMU_EFI.fd

Your folder will be displayed like:

# ls
my-seed.img   QEMU_EFI.fd  xenial-server-cloudimg-arm64-uefi1.img
my-user-data  start.sh
# cat start.sh
qemu-system-aarch64 \
    -smp 2 \
    -m 1024 \
    -M virt \
    -cpu cortex-a57 \
    -bios QEMU_EFI.fd \
    -nographic \
    -device virtio-blk-device,drive=image \
    -drive if=none,id=image,file=xenial-server-cloudimg-arm64-uefi1.img \
    -device virtio-blk-device,drive=cloud \
    -drive if=none,id=cloud,file=my-seed.img \
    -device virtio-net-device,netdev=user0 \
    -netdev user,id=user0 \
    -redir tcp:2222::22

start the shell script, then login with ssh -p2222 ubuntu@localhost, you will get an emulated arm environment.

The default size of the / partition is only 2G, need to growpart to 40G, the steps are listed as following(add 2 lines into the my-seed):

#cloud-config
growpart:
  mode: auto

Edit the mirrored pkgs via:

# vim /etc/apt/sources.list
deb http://192.168.0.100/arm64repo/mirror/ports.ubuntu.com/ xenial main restricted universe

# apt-get update

Enable the vnc:

# qemu-system-aarch64 ...... -vga std -vnc 127.0.0.1:33

BenchMark
