Hello Stefan, The qemu used by me is the one installed using apt-get install qemu. The executable is in /usr/bin. The KVM driver is the one supplied with Ubuntu 13.04.
The version of qemu is 1.4.0 (after running qemu --version I get the message --- QEMU emulator version 1.4.0 (Debian 1.4.0+dfsg-1expubuntu4), Copyright (c) 2003-2008 Fabrice Bellard You mean I should use the build-from-sources qemu (getting the sources from git://git.qemu-project.org/qemu.git) ? Should I then compile from sources and mount the KVM ?
