Ok, another observation: I was using qemu from sources from the other day: v2.0.0-1806-g2b5b7ae917e8 Switching back to the installed one: $ qemu-system-x86_64 --version QEMU emulator version 1.7.1 (Debian 1.7.0+dfsg-6), Copyright (c) 2003-2008 Fabrice Bellard fixes the issue. Joerg says I should bisect but I'm busy with other stuff. If people are interested in chasing this further, I could free up some time to do so... -- Regards/Gruss, Boris.
