This function may require privileged access to the hypervisor.
The domain is not persistent, so its definition will disappear when it
is destroyed, or if the host is restarted (see virDomainDefineXML() to
define persistent domains).
@files provides an array of file descriptors which will be
made available to the 'init' process of the guest. The file
handles exposed to the guest will be renumbered to start
from 3 (ie immediately following stderr). This is only
supported for guests which use container based virtualization
technology.
If the VIR_DOMAIN_START_PAUSED flag is set, the guest domain
will be started, but its CPUs will remain paused. The CPUs
can later be manually started using virDomainResume.
If the VIR_DOMAIN_START_AUTODESTROY flag is set, the guest
domain will be automatically destroyed when the virConnectPtr
object is finally released. This will also happen if the
client application crashes / loses its connection to the
libvirtd daemon. Any domains marked for auto destroy will
block attempts at migration, save-to-file, or snapshots. """
