Wed Nov 15 15:08:13 EST 2006 Daniel Berrange <berrange@redhat.com>
* src/xen_internal.c, src/xs_internal.c, src/xend_internal.c,
src/proxy.c: Don't try to invoke APIs if domain is is < 0, letting
these inactive domains be handled by other driver backend.
* src/xend_internal.h: make xend_config_version() api available
to other drivers
Wed Nov 15 14:59:13 EST 2006 Daniel Berrange <berrange@redhat.com>
* src/hash.c, src/hash.h: Added three new methods for iterating
over hashtable entries, virHashForEach, virHashRemoveSet &
virHashSearch.
Wed Nov 15 15:52:01 EST 2006 Daniel Berrange <berrange@redhat.com>
Wed Nov 15 14:52:01 EST 2006 Daniel Berrange <berrange@redhat.com>
* src/conf.c, src/conf.h: Add two new APIs virConfNew() and
virConfSetValue() for creating & populating new config objects
in memory instead of from a file
Wed Nov 15 15:42:01 EST 2006 Daniel Berrange <berrange@redhat.com>
Wed Nov 15 14:42:01 EST 2006 Daniel Berrange <berrange@redhat.com>
* python/libvir.c, python/libvirt_wrap.h, python/types.h: Ensure
that unsigned longs are marshalled to python Long type instead
