I can't see how the host is supposed to enforce and handle it. Pause the VM? Crash it? raise ENOMEM\ENOSPC in the guest? Also what about cases of KSM\QCow2, disk\memory overcommit. Disk Templates. Storage for hibernation disk. Temporary and shared disks. Shared disks between VMs owned by different users. Backup snapshots (should they count in the quota? They are transient) I also don't see how vcpu limiting is any good? I don't even know what it means. What happens in migration between hosts with different amount of physical CPUs? I also don't think CPU limiting is even a thing to be managed by a quota. There is no reason not to use 100% of the CPU if you are the only VM active. CPU scheduling should use a priority model and not a quota IMHO.
