Hi Actually I am using 2.6.21 kernel and inserting kvm-76 module. It is fine when I am using cpu affinity( like " taskset 1 ./qemu-system-x86-64 -hda imgage name "). I am having quad core intel xeon processor. But without cpu affinity It is hanging randomly.(./qemu-system-x86-64 -hda imgage name) Give me any suggestion ______________________________________________________________________ -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
