[Libvir] libver-python fix & test script
Against the current CVS version, the python method libvir.open() is
failing because it requires "name" as a parameter, but in src/libvir.c,
virConnectOpen returns NULL if name is set. Very simple patch attached.
Also attached is a simple script to test reporting of domain state via
the python bindings. Hopefully useful as a test of the python
bindings/simple example of how to use them. It generates output like this:
[root@chaka ~]# ./libver-python-test
Attached to a hypervisor of type - Xen
There are currently 2 domains running
Domain ID 0 is named Domain-0
State is Running
maxMem is -4
memory is 262224
nrVirtCpu is 1
cpuTime is 2294771524162
Domain ID 2 is named guest1
State is Blocked
maxMem is 131072
memory is 131052
nrVirtCpu is 1
cpuTime is 34682760385
