VmSchedulerSpaceShared is a VMM allocation policy that allocates one or more PEs from a host to a Virtual Machine Monitor (VMM), and doesn’t allow sharing of PEs. The allocated PEs will be used until the VM finishes running. If there is no enough free PEs as required by a VM, or whether the available PEs doesn’t have enough capacity, the allocation fails. In the case of fail, no PE is allocated to the requesting VM.
