Cause they seem to appear at the same time, when the guest tries to mount root..

What I meant is $ qemu -version QEMU emulator version 1.5.1 (Debian 1.5.0+dfsg-5), Copyright (c) 2003-2008 Fabrice Bellard => 1.5.1 But the package version is 1.5.0-5 ... (.0 vs. .1) so I just blindly guessed there might have been some mix ups. Thanks, Chris.
