Yes, the qemu-process is started with my user and my user is member of group kvm, which has read-write-access to /dev/kvm. Additionally my user has read-write-access to /dev/kvm. But am unsure who this contributes to the huge difference in runtime. If the qemu process does not have access to kvm, then *both* types of VMs would be affected in the same way, would they? --=20 Regards Hartmut Goebel | Hartmut Goebel | h.goebel@crazy-compilers.com | | www.crazy-compilers.com | compilers which you thought are impossible |
