I love the ability to limit disk, network and CPU for a given VM/disk/adapter.

Is there any way to limit IO and CPU for a *group* of VMs? ie. build a set of VMs connected to their own disks and specify that the total IO (or CPU) for that group should be limited to a certain value.

I know that Linuz will allow group limits for CPU, but was hoping for something inside VirtualBox.

Not really, not at this point. The limits are imposed per VM.
