[libvirt] [PATCH 1/9] Extend v3 migration protocol to allow app supplied XML for target

[Matthias Bolte]

2011/5/24 Daniel P. Berrange <berrange at redhat.com>:
> This extends the v3 migration protocol such that the
> virDomainMigrateBegin3 and virDomainMigratePerform3
> methods accept an application supplied XML config for
> the target VM.
>
> If the 'xmlin' parameter is NULL, then Begin3 uses the
> current guest XML as normal. A driver implementing the
> Begin3 method should either reject all non-NULL 'xmlin'
> parameters, or strictly validate that the app supplied
> XML does not change guest ABI.
>
> The Perform3 method also needed the xmlin parameter to
> cope with the Peer2Peer migration sequence.
>
> NB it is not yet possible to use this capability since
> neither of the public virDomainMigrate/virDomainMigrateToURI
> methods have a way to pass in XML.

> * daemon/remote.c, src/remote/remote_driver.c,
