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.

Playing games with field offsets in a struct causes all sorts
of alignment warnings on ARM platforms
util/virkeycode.c: In function '__virKeycodeValueFromString':
util/virkeycode.c:26:7: warning: cast increases required alignment of target type [-Wcast-align]
(*(typeof(field_type) *)((char *)(object) + field_offset))
^
util/virkeycode.c:91:28: note: in expansion of macro 'getfield'
const char *name = getfield(virKeycodes + i, const char *, name_offset);

return getfield(virKeycodes + i, unsigned short, to_offset);
There is no compelling reason to use a struct for the keycode
tables. It can easily just use an array of arrays instead,
avoiding all alignment problems

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
