Yes, it should, but one important thing since 1.0 has been the merger of
qemu-kvm and QEMU.  What distribution are you using?  I know Fedora
allows qemu-kvm-1.0 to QEMU-1.6 compatibility, but I don't know about
others.

Michael Tokarev is the maintainer of the Debian package, so he may be
able to answer.

Alternatively, you can modify your utility to simply add 512 MB to the
