"""Launch a defined domain. If the call succeeds the domain moves from the

defined to the running domains pools.
|

@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, or if the guest domain
|
|
has a managed save image that requested paused state (see
|
|
virDomainManagedSave()) the guest domain will be started, but its
|
|
CPUs will remain paused. The CPUs can later be manually started
|
|
using virDomainResume(). In all other cases, the guest domain will
|
|
be running.
|
|
|
|
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.
|
|
|
|
If the VIR_DOMAIN_START_BYPASS_CACHE flag is set, and there is a
|
|
managed save file for this domain (created by virDomainManagedSave()),
|
|
then libvirt will attempt to bypass the file system cache while restoring
|
|
the file, or fail if it cannot do so for the given system; this can allow
|
|
less pressure on file system cache, but also risks slowing loads from NFS.
|
|
|
|
If the VIR_DOMAIN_START_FORCE_BOOT flag is set, then any managed save
|
|
file for this domain is discarded, and the domain boots from scratch. """
