Representation of virtual machines A virtual machine is directly associated with a z/VM user ID or logon identifier.

During its time slice, a guest actually runs on the real machine. The hardware microcode handles most guest program instructions and CP takes control only when necessary, which maintains good performance.

    Overview of z/VM capacity planning An important element of z/VM capacity planning is knowing what z/VM is good at: the value of z/VM is its ability to consolidate distributed Linux workloads that under-utilize CPUs or do not require peak processing at the same time. z/VM improves the cost and performance efficiencies because it shares CPU cycles among virtual servers that, if distributed on separate servers, would be idle.
