[libvirt-users] free memory on hypervisor

i am trying to get the free memory on a hypervisor using libvert, with the python api bindings as per http://libvirt.org/python.html, it should be pretty easy, however the below is failing: #conn is a connection object freemem=libvirt.virNode.getFreeMemory(conn) although this works fine: software=libvirt.virConnect.getType(conn) if software ==  'QEMU': logging.debug('hypervisor is type QEMU')
