Hi Ronny,
since this is code from the kernel, it is implicitly GPLv2 licensed.
systemd is suppose to be / become LGPLv2+ as a whole, and including this
make this impossible. But anyway, I think that large parts of are not
necessary for us:
- we don't care about old qemu versions, we always assume that
a person running systemd from git has bleeding edge versions of
all dependencies updated from the experimental branch each morning,
- we don't care about insane people who compile qemu from source,
instead of using the package manager. (I know that this contradicts
the first point, but who said that developer's life is easy ;) )
- if something is missing just say so, no explanation or instructions
necesary.
Otherwise the changes look OK.

I think if you say
QEMU_BIN=$(LANG=C which qemu qemu-kvm qemu-system-$ARCH | grep '^/' -m1)
the effect will be similar without all the verbosity.
