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

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 ---  tools/virsh.c |   19 +++++++++++++++++--  1 files changed, 17 insertions(+), 2 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index b43c167..fd32309 100644 --- a/tools/virsh.c +++ b/tools/virsh.c
