QEMU AArch64

QEMU is a open source machine emulator.

Installing QEMU

Install QEMU 6.2.0 or later. (You can use vanilla QEMU.)
You can use the following packages on openSUSE Leap 15.4.

sudo zypper in qemu-arm qemu-tools

Creating a bridge interface on your PC

Create a bridge interface for using network from the QEMU virtual machine.
Create the file /usr/local/etc/qemu/bridge.conf (or /etc/qemu/bridge.conf) with the content:

allow br0

Creating a disk image

The following additional packages are required on openSUSE Leap 15.4.

zypper install gptfdisk

You need to use Solaris ROOT GUID (6A85CF4D-1DD2-11B2-99A6-080020736631) for the root slice.

disk_img=${base_dir}/disk-a64.img

qemu-img create -f raw ${disk_img} 16G
sgdisk -g -e --clear --new=1:2048: --change-name=1:solaris --typecode=1:6A85CF4D-1DD2-11B2-99A6-080020736631 ${disk_img}

Booting from network

Run the following command. When booting from network, some errors occurr but you can ignore errors.
You can login as root without using password.

illumos_dir=${base_dir}/illumos-gate
disk_img=${base_dir}/disk-a64.img

Partition

The solaris root partition will probably be /dev/dsk/c1t0d0s0.
To create a storage pool:

devfsadm
zpool create -f -o altroot=/mnt rpool /dev/dsk/c1t0d0s0

Booting from disk image

Run the following command. The difference with the network boot is -append "-D /virtio_mmio@a003c00".

illumos_dir=${base_dir}/illumos-gate
disk_img=${base_dir}/disk-a64.img

WARNING: Reboot required.
The system has updated the cache of files (boot archive) that
is used during the early boot sequence. To avoid booting and
running the system with the previously out-of-sync version of
these files, the system will be restarted.
