[libvirt] Get Info for QEMU/KVM storage and volume

Hi all, I am new to libvirt. Right now I am trying to use libvirt to get statistics information (size, free space and so on) on host storage and vm volume running on QEMU/KVM hypervisor. However when I looked at the API support matrix: http://libvirt.org/hvsupport.html#virStorageDriver It seems the storage pool APIs do not support QEMU/KVM even for the latest version of libvirt. Can anyone suggest any workaround solution? Or will there be any plan in the future for libvirt to support that? Thanks in advance, Bruce
