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 the VM configuration option stealclock.enable = "TRUE". It is supported by VMs that run hardware version 13 or newer. Introduce the VMware steal time infrastructure. The high level code (such as enabling, disabling and hot-plug routines) was derived from KVM.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
