+ * configure.in src/Makefile.am: adding dependency to libxml2
+ * include/libvirt.h* src/libvirt.c src/xend_internal.[ch]
+ src/xml.[ch]: added XML parsing for Xen domain descriptions
+ needed for creates, plugged in a converter to s-exp and
+ xend call. Modified the virDomainCreateLinux() to reflect
+ that XML based description. Seems to work.
+ * python/tests/create.py: added a test case which seems to work
+ not tested much yet
+ * docs/*: regenerated
