All of it except for that! Your VM isn't just a process accessing a disk. With KVM they've attacked the most commond devices - network and disk and offered paravirtualized devices. This doesn't concern me as the speed has proven to be good although in mysqlbench Xen still leads by quite a bit. I'm concerned about everything else. With 41 interactive VMs I worry about how fast the hypervisor can switch focus, the cpu utilization of each etc..
What are the hardware specs you're running your 41 VM's off of just out of curiosity?
