Generic shared impls of all NUMA apis
* src/libvirt_private.syms: Add all nodeinfo.c APIs
* src/lxc_conf.c, src/openvz_conf, src/qemu_conf.c,
src/vbox/vbox_tmpl.c, src/uml_conf.c: Update for
changed API names in nodeinfo.h
* src/nodeinfo.c, src/nodeinfo.h: Add generic impls of
the virNodeGetCellsFreeMemory & virNodeGetFreeMemory APis
* src/openvz_driver.c: Use nodeGetInfo() directly in driver
* src/qemu_driver.c, src/uml_driver.c: Remove NUMA APis impls
in favour of generic impl in nodeinfo.c
Wed Jun 3 14:12:47 CEST 2009 Daniel Veillard <veillard@redhat.com>
* src/openvz_conf.c src/virsh.c: various typo or english fixups
