Hoi, Just a point on the timeline.... I think somebody asked why his CPU load was so high on AMD running linux. I've completed compiling a "fresh" linux-kernel on my Ubuntu 14.04 system, installed and rebooted it. And where previously a Linux-kernel would drain the CPUs it got assigned to the max... Aka 2 CPU would drive the load +2 and top would diskplay a 200% cpu. With the new kernel, that is no longer the case. On a idle vm the CPU load is like 6-7%.... At the moment I'm running: linux-image-3.13.0-24-generic_3.13.0-24.46_amd64 So somewhere in the interaction between bhyve idle detection and the older linux kernel things do not match... --WjW
