First, sorry about the systemd list, I did not know it's

This is Frugalware Linux, and it's disabled by default here as well.


Sure - here is a qcow image (871M):

Here is how I started it:

qemu-kvm -vnc :0 -m 1G -hda systemd.img

$ qemu-kvm -version

There are two menu entries in grub config - first is sysvinit, that
boots up correctly here, you can login using root / root. The second is
systemd, that just panics here almost all the time. In case it would
not, use 'systemctl emergency' as root and that will trigger the bug. :)

If you need more packages in the virtual machine and the pacman package
manager sounds exotic, here is a quick help:
