RHEL 7 includes a hypervisor and a number of virtualization tools, which allows running guest operating systems, so it can function as a virtualization platform. However, the solution supports a limited number of guests per host and a limited range of guest types.

Red Hat Virtualization is an enterprise virtualization solution based on the KVM technology, offering more features than Red Hat Enterprise Linux.

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.
