Mon Nov 17 11:57:00 GMT 2008 Daniel Berrange <berrange@redhat.com>
Push stateful driver code into daemon binary
* src/Makefile.am: Don't build QEMU, LXC, Network & Storage
drivers into libvirt.so
* src/libvirt.c: Don't call into QEMU, LXC, network & storage
driver register methods
* src/libvirt_sym.version.in: Export a bunch of internal
symbols to libvirtd for use by drivers
* tests/Makefile.am: Link to driver modules which are not
in libvirt.so
* qemud/Makefile.am: Directly link to QEMU, LXC, network
and storage drivers
* qemud/qemud.c: Initialize QEMU, LXC, network & storage
drivers at startup
Mon Nov 17 11:40:00 GMT 2008 Daniel Berrange <berrange@redhat.com>
Push URI probing down into individual drivers' open methods
