noch etwas zum Hintergrund wieso VT eigentlich sein sollte

http://en.wikibooks.org/wiki/QEMU/Installing_QEMU
QEMU by itself isn't very fast, as it does a lot of emulation even when running on the hardware compatible with the guest operating system. To make it perform better, QEMU has a kernel module called KVM that allows much of the guest OS's code to run directly on the host processor when running on x86 or x86-64 processors with virtualisation extensions under Linux. For example, if the host is x86 Linux and the guest is Windows XP, then KVM can run most of the Windows XP code directly on the processor without emulation.
QEMU-KVM requires a Linux or BSD Unix host, and a CPU with virtualisation extensions -- either Intel VT or AMD-V.
