Beispiel #2
// UpdateDevice changes a virtual device on a domain, using the flags parameter
// to control how the device is changed. DomDeviceModifyCurrent specifies that
// the device change is made based on current domain state. DomDeviceModifyLive
// specifies that the device shall be changed on the active domain instance
// only and is not added to the persisted domain configuration.
// DomDeviceModifyConfig specifies that the device shall be changed on the
// persisted domain configuration only. Note that the target hypervisor must
// return an error if unable to satisfy flags. E.g. the hypervisor driver will
// return failure if DomDeviceModifyLive is specified but it only supports
// modifying the persisted device allocation.
