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) There are 2 wrongs in here, the first, libvirt module hasn't 'virNode' class, it should be 'virNodeDevice';

import libvirt conn = libvirt.open(None) conn.getFreeMemory() 228167680L
or
libvirt.virConnect.getFreeMemory(conn) 227864576L
You may use 'dir' to list all of class/method of libvirt/sub-class:
dir(libvirt) dir(libvirt. virConnect)
although this works fine:
software=libvirt.virConnect.getType(conn) if software == 'QEMU': logging.debug('hypervisor is type QEMU')
