Hello,

first of all thank you very much for your reply.

The hint with the libvirt log pointed me into the right direction. While 
executing the virt-install cmd there was an error in the libvirt.log:

12:03:11.938: 3137: error : qemuCapsParseHelpStr:1165 : internal error 
cannot parse /usr/bin/qemu-system-x86_64 version number in 'QEMU 
emulator version 1.0 (qemu-kvm-1.0), Copyright (c) 2003-2008 Fabrice 
Bellard'


Google for that error pointed me to a bug report. This bug still seems 
to be in the qemu-kvm version I was using (1.0-r2). Upgrading to version 
9999 seemed to solve my issue. I don't get the error anymore and will 
now try to setup a virtual machine.


Kind regards,
Felix Blanke
