Libc is basically irrelevant here.  What matters are the host kernel
and kvm version.

What's the bios files your kvm uses?  Are they by a change
from some old qemu install?

Does kvm deb from http://www.corpit.ru/debian/tls/kvm/ expose the same
issue?

Well, that's telling, isn't it?  If you change disk image and
it works, the problem should be in the disk image...

There's no kvm/bin directory in the source tarball of qemu-kvm-0.11.0.
