Yeah, that's what I thought.

It's defined statically at src/qemu/qemu_conf.c:1384 in libvirt 0.8.3
[1].

Yeah, I'm trying to set up virtual machines in an old host system, which
I plan to reinstall – likely with a newer OS version – after I move all
of its services to the VMs. :)
I installed backported packages of libvirt 0.9.12 and qemu-kvm 1.1.2.
Running virt-install again failed, but this time QEMU gave a rather
helpful error message:

Domain installation does not appear to have been
successful. If it was, you can restart your domain
by running 'virsh start test1'; otherwise, please
restart your installation.

(This error message is from qemu_memalign() at oslib-posix.c:95 in
qemu-kvm 1.1.2 [2].)
Apparently I misunderstood the units of the --ram option value… On my
system which has 2 GiB of RAM, running virt-install with a --ram option
value of "128" (128 MiB) instead of "$((128 * 1024 * 1024))" (128 TiB!)
worked much better. :)
So this is just a case of user error, hidden by a lack of output in an
old version of QEMU.

Thanks for the help, and sorry for the noise over such a mistake,
