Hi devs & users,
The Telemetry service of OpenStack, project code name Ceilometer, is using libvirt.domain.blockInfo() to get disk's physical, allocation and capacity information [1]. However, when disk is network type with protocol ceph, the blockInfo() always fail with: libvirtError: internal error: missing storage backend for network files using rbd protocol. [2]
After reading some libvirt code, I think it might due to blockInfo() always assume disk is file backend [3], and file backend doesn't support network type [4].
I want to know if such limitation is by design?
- If yes, then how should I get the network type disk's physical, allocation and capacity info?
- If not, is there any plan to implement it?
Thanks!
