* include/libvirt.h include/libvirt.h.in doc/*: added new entry point
virDomainSetMemory to set up the target memory use for a domain * src/driver.h src/libvirt.c src/xen_internal.c src/xend_internal.[ch] src/xs_internal.[ch]: added a new entry point in the drivers for this, also fixed the xen store entry, as changing /local/domain/$$/memory/target affects the target memory not the max, apparently max is not visible at the xenstore level (or I missed it) Daniel
