Michal Privoznik aad31f46fb qemuBuildNumaArgStr: Use modern -numa memdev= if old -numa mem= is unsupported
In previous commit we started tracking whether QEMU supports
'-numa mem='. This is tied to the machine type because migration
from '-numa mem=' to '-numa memdev' is impossible (or vice
versa). But since it's tied to a machine type (where migration
from one to another is also unsupported) we can allow QEMU to get
rid of the deprecated command line.

==============================
Libvirt API for virtualization
==============================

Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.

Further information about the libvirt project can be found on the
website:

https://libvirt.org


License
=======

The libvirt C API is distributed under the terms of GNU Lesser General
Public License, version 2.1 (or later). Some parts of the code that are
not part of the C library may have the more restrictive GNU General
Public License, version 2.0 (or later). See the files ``COPYING.LESSER``
and ``COPYING`` for full license terms & conditions.


Installation
============

Libvirt uses the GNU Autotools build system, so in general can be built
and installed with the usual commands, however, we mandate to have the
build directory different than the source directory. For example, to build
in a manner that is suitable for installing as root, use:

::

  $ mkdir build && cd build
  $ ../configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
  $ make
  $ sudo make install

While to build & install as an unprivileged user

::

  $ mkdir build && cd build
  $ ../configure --prefix=$HOME/usr
  $ make
  $ make install

The libvirt code relies on a large number of 3rd party libraries. These will
be detected during execution of the ``configure`` script and a summary printed
which lists any missing (optional) dependencies.


Contributing
============

The libvirt project welcomes contributions in many ways. For most components
the best way to contribute is to send patches to the primary development
mailing list. Further guidance on this can be found on the website:

https://libvirt.org/contribute.html


Contact
=======

The libvirt project has two primary mailing lists:

* libvirt-users@redhat.com (**for user discussions**)
* libvir-list@redhat.com (**for development only**)

Further details on contacting the project are available on the website:
