Steal Time
"Steal time" is the percentage of time a virtual CPU waits for real CPU while the hypervisor is servicing another virtual processor.
A high value means the physical CPU is overcommitted and more physical CPU should be allocated to the environment - or the VM should be moved on a different physical server. The steal time is reported by vmstat st.
