Steal time is the amount of CPU time needed by a guest
virtual machine that is not provided by the host. Steal
time occurs when the host allocates this CPU time
elsewhere: for example, to another guest.

Steal time can be enabled by adding VM configuration option
stealclock.enable = "TRUE". It is supported by VMs that run
hardware version 13 or newer.
