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.

Daniel Henrique Barboza f1ea75233b qemu: make Hyperv settings exclusive to x86 and aarch64
Hyperv features are supported by both x86 and aarch64. The <hyperv/>
declaration in the XML by itself is benign to other architectures,
but any of its 14 current features will break QEMU with an error
like this (from ppc64):

qemu-kvm: Expected key=value format, found hv_relaxed

This is a more extreme case than the one for apic eoi because we
would need an extra 'switch' statement, with all current Hyperv
features in the body of qemuDomainDefValidateFeatures(), to
check if the user attempted to activate any of them. It's easier to
simply fail to launch with any 'hyperv' declaration in the XML for
every arch which is not x86 and aarch64.

A fair disclaimer about Windows and PowerPC: the last Windows version
that ran in the architecture is the hall of famer Windows NT 4.0,
launched in 1996 and with end of extended support for the Server
version in 2004 [1]. I am acknowledging that there might be Windows
NT 4.0 users running in PowerPC, but not enough people running it
under KVM/QEMU to justify Libvirt allowing 'hyperv' to exist in the
domain XML of ppc64 domains.

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:
