Hell, too many variables. It looks like the kernel modules have some if not the ultimate impact: kvm-mod-2.6.31.6b on my 2.6.27 host works fine, kvm-kmod stable-2.6.32 as well as master cause troubles. What is your host kernel and/or kvm module version? Jan -- Siemens AG, Corporate Technology, CT T DE IT 1 Corporate Competence Center Embedded Linux
