[libvirt] [PATCH 3/8] Add virDomainBlockPull support to the remote driver
Adam Litke
agl at us.ibm.com
Thu Jun 9 17:10:09 UTC 2011
The generator can handle DomainBlockPullAll and DomainBlockPullAbort.
DomainBlockPull and DomainBlockPullInfo must be written by hand.
* src/remote/remote_protocol.x: provide defines for the new entry points
* src/remote/remote_driver.c daemon/remote.c: implement the client and
server side
* src/remote_protocol-structs: structure definitions for protocol verification
