The bug is that the libvirt driver is reporting 'total' for 'DISK_GB' as 0 when the placement API does not allow this. This bug also exists on the master branch. Instead, for all resources we need to check whether there is > 0 available and only report them if that is the case. Else, we should not include them in the PUT request, which will result in the resource inventory being removed from placement (as PUT does a full replace [2]), which is the way that placement is intended to work. We are already doing this for other resource classes like 'VCPU' [3].
