Debian qemu-system-sparc64

Motivation

Required packages

The minimum packages required are

apt-get install qemu-system-sparc openbios-sparc qemu-utils qemu-system-common

If you plan on using libvirt to help manage VMs

apt-get install libvirt-daemon libvirt-daemon-system

And adding virt-manager if you like GUIs

apt-get install virt-manager

Using qemu-system-sparc64 command line

hard drive and d-i image

Once you have a virtual disk created, e.g.

qemu-img create -f qcow2 -o size=8G /path/to/vm/images/default/debian-unstable-sparc64.qcow2

As of 2016-06-28 you will need a d-i iso from

https://people.debian.org/~glaubitz/debian-cd/

Short form

Short form of qemu-system-sparc64, limited networking

qemu-system-sparc64 -hda /path/to/vm/images/default/debian-unstable-sparc64.qcow2 -cdrom /path/to/vm/images/default/iso/debian-9.0-sparc64-NETINST-1.iso -boot once=d -serial pty -nographic -m 160

Access the VM via

minicom -p /dev/pty/X

Longer form

Longer form of qemu-system-sparc64, shows a little more of the defined system features

LC_ALL=C QEMU_AUDIO_DRV=none \
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin \
/usr/bin/qemu-system-sparc64 -name debian-unstable-sparc64 -machine sun4u,accel=tcg,usb=off -m 1024 \
-realtime mlock=off -smp 1,sockets=1,cores=1,threads=1 \
-uuid ccd8b5c2-b8e4-4d5e-af19-9322cd8e55bf -rtc base=utc -no-reboot -no-shutdown \
-boot strict=on \
-drive file=/path/to/vm/images/default/debian-unstable-sparc64.qcow2,if=none,id=drive-ide0-0-1,format=qcow2,cache=none,aio=native \
-device ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-1,id=ide0-0-1 \
-netdev user,id=hostnet0,hostfwd=tcp::5555-:22 \
-device e1000,netdev=hostnet0,id=net0,mac=52:54:00:ce:98:e8 \
-msg timestamp=on -serial pty -nographic

Connect to the VM's serial via PTY e.g. from minicom

minicom -p /dev/pty/X

This still uses user-mode networking with forwarding on localhost:5555 to VMs port 22 for ssh access.

VM setup using virsh and xml

If you plan to use libvirt to manage your VMs use virsh to import your xml Populate the default libvirt system session, or your can just populate a libvirt's user-session by omitting the URI

virsh -c qemu:///system define debian-unstable-sparc64.xml

This is an example XML, using libvirt 'default' network and virtio nic

Running debian-installer

When connected to the serial console you can run through the d-i as normal

Notes

Create/edit /etc/modprobe.d/drm-blacklist.conf

# blacklist of DRM modules that do not load on qemu-system-sparc64 sun4u
blacklist drm
blacklist bochs-drm
blacklist ttm

Edit /etc/initramfs-tools/initramfs.conf

#MODULES=most
MODULES=dep

Example, add entry into /etc/silo.conf

image = /vmlinuz
        label = linux-emergency
        append = "initrd=/initrd.img root=/dev/sda1 systemd.unit=emergency.target"

If you need even less running try

image = /vmlinuz
        label = linux-light
        append = "initrd=/initrd.img init=/bin/sh"
