Export kernel paravirt features to user space, so that VMM can control each single paravirt feature. By default paravirt features will be the same with kvm supported features if VMM does not set it. Also a new feature KVM_FEATURE_VIRT_EXTIOI is added which can be set from user space. This feature indicates that the virt EIOINTC can route interrupts to 256 vCPUs, rather than 4 vCPUs like with real HW.

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 reStructuredText 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.
