[libvirt] Storage api problem
Hi, I am just trying to use libvirt storage api from python terminal, and i am getting the following error. import libvirt con = libvirt.open(my uri using ssh) con.numOfDefinedStoragePools() libvir: Remote error : Broken pipe Traceback (most recent call last): File stdin, line 1, in module File /usr/lib/python2.5/libvirt.py, line 1022, in numOfDefinedStoragePools ret = libvirtmod.virConnectNumOfDefinedStoragePools(self._o) AttributeError: 'module' object has no attribute 'virConnectNumOfDefinedStoragePools' I have checked in the libvirt.c file and the function virConnectNumOfDefinedStoragePools(virConnectPtr conn) is implemented.

This feature appears to have been introduced in gcc-3.1, so define
away for earlier versions.
Also, it's better for name-space cleanliness to use the __...__ form:
#ifndef VIR_DEPRECATED
/* The feature is present in gcc-3.1 and newer. */
# if __GNUC__ 3 || (__GNUC__ == 3 __GNUC_MINOR__ = 1)

Re: [libvirt] How to solve the runtime error: libvir: Remote error :unknown procedure: 72?
Hi, It seems libvirtd vs. remote_internal.c(on virsh) incompatibility. Please check qemud/remote_protocol.x code which is used in libvirtd. The number 72 corresponds REMOTE_PROC_LIST_STORAGE_POOLS.

[libvirt] PATCH: Fix python binding for listing storage pools/volumes
The python binding for the APIs to list storage pools and volumes has a hand written C layer, but an auto-generated python layer. The latter was auto-generating incorrectly, so this patch overrides its API contract making the generator work correctly. Dan.
