[libvirt] Interface driver and ESX support

I'm trying to get a feel of the python binding and the esx driver Trying to get the number of interfaces hit(as anticipated) a non-support wall: Traceback (most recent call last):   File "test.py", line 362, in ?     vmm.refresh()   File "test.py", line 189, in refresh     print self.conn.numOfDefinedInterfaces()   File "/usr/lib/python2.4/site-packages/libvirt.py", line 1347, in numOfDefinedInterfaces     if ret == -1: raise libvirtError ('virConnectNumOfDefinedInterfaces() failed', conn=self) libvirt.libvirtError: this function is not supported by the hypervisor: virConnectNumOfDefinedInterfaces I'm wondering how to fix it can I register the esx driver as the interface driver? so I can use the ESX web-services to handle all the interface issues that normally(?) netcf would handle? if yes - how is it done? I thought that configure --without-netcf would do the trick(it didn't-I think) Thanks Shahar
