|

|
|
|
|
*
|
|
|
|
* Migrate the domain object from its current host to the destination
|

|
|
* host given by dconn (a connection to the destination host).

|
* Flags may be one of more of the following:
|
|
|
|
* VIR_MIGRATE_LIVE Attempt a live migration.
|
|
|
|
*
|
|
|
|
* If a hypervisor supports renaming domains during migration,
|
|
|
|
* then you may set the dname parameter to the new name (otherwise
|
|
|
|
* it keeps the same name). If this is not supported by the
|
|
|
|
* hypervisor, dname must be NULL or else you will get an error.
|
|
|
|
*
|
|
|
|
* Since typically the two hypervisors connect directly to each
|
|
|
|
* other in order to perform the migration, you may need to specify
|
|
|
|
* a path from the source to the destination. This is the purpose
|
|
|
|
* of the uri parameter. If uri is NULL, then libvirt will try to
|
|
|
|
* find the best method. Uri may specify the hostname or IP address
|
|
|
|
* of the destination host as seen from the source. Or uri may be
|
|
|
|
* a URI giving transport, hostname, user, port, etc. in the usual
|
|
|
|
* form. Refer to driver documentation for the particular URIs
|
|
|
|
* supported.
|
|
|
|
*
|
|
|
|
* The maximum bandwidth (in Mbps) that will be used to do migration
|
|
|
|
* can be specified with the bandwidth parameter. If set to 0,
|
|
|
|
* libvirt will choose a suitable default. Some hypervisors do
|
|
|
|
* not support this feature and will return an error if bandwidth
|
|
|
|
* is not 0.
|
|
|
|
*
|
|
|
|
* To see which features are supported by the current hypervisor,
|
|
|
|
* see virConnectGetCapabilities, /capabilities/host/migration_features.
|
|
|
|
*
|
|
|
|
* There are many limitations on migration imposed by the underlying
|
|
|
|
* technology - for example it may not be possible to migrate between
|
|
|
|
* different processors even with the same architecture, or between
|
|
|
|
* different types of hypervisor.
|
|
|
|
*
|
|
|
|
* Returns the new domain object if the migration was successful,
|
|
|
|
* or NULL in case of error. Note that the new domain object
|
|
|
|
* exists in the scope of the destination connection (dconn).
