In the reverted commit d2e5538b1, the libxl driver was changed to copy interface names autogenerated by libxl to the corresponding network def in the domain's virDomainDef object. The copied name is freed when the domain transitions to the shutoff state. But when migrating a domain, the autogenerated name is included in the XML sent to the destination host. It is possible an interface with the same name already exists on the destination host, causing migration to fail.
This patch defines a new capability for setting the network device prefix that will be used in the driver. Valid prefixes are VIR_NET_GENERATED_PREFIX or the one announced by the driver.
