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.
