[libvirt] [PATCH 2/4] Allow virsh to pass in a custom XML document for migration

[Matthias Bolte]

2011/5/27 Daniel P. Berrange <berrange at redhat.com>:
> Switch virsh migrate over to use virDomainMigrate2 and
> virDomainMigrateToURI2. This is still compatible with
> older libvirts, because these methods dynamically choose
> whether to perform v1, v2 or v3 migration based on declared
> RPC support from the libvirtd instances
>
> Add a --xml arg which allows the user to pass in a custom
> XML document. This XML document must be ABI compatible
> with the current *live* XML document for the running guest
> on the source host. ABI compatibility will be enforced by
> any driver supporting this function
>
> * tools/virsh.c: Add '--xml' arg to migrate command

Additional empty lines, could be removed here.
