I'm trying to make my VirtualBox only using certain CPU's (Quad-Core with Hyper-threading). I've isolated CPU 4 till 7 (0 till 3 used for the system) and created a group where the isolated CPU's are added.
The problem I'm experiencing is when starting the the application with "sudo cgexec -g cpuset:vbox --sticky sudo -i -u djnightchild virtualbox", VirtualBox only uses cpu 4.
I've tried switching the load balancing "cgset -r cpuset.sched_relax_domain_level=1 vbox" but then I get the error: "cgset: the group can't be modified."
I know I can assign how many CPU's I want to use in VBoxManager, but I want to force VBox using the isolated cores.
