This really surprises me. I expected that we can collect trace for a specific VM. But it seems that we always trace all the VMs currently running?? With trace feature always ON, I guess we suffer some overhead, right? Perhaps the overhead is little, but still we have. If so, is there anyway to turn the trace feature OFF?
