We've had a report of a particular vCenter server (using VMware clustering, we think) where virStorageVolInfo of a guest volume fails with: Storage volume not found: No storage volume with key or path '[...] ...' The error comes from esxVI_LookupFileInfoByDatastorePath: https://libvirt.org/git/?p=libvirt.git;a=blob;f=src/esx/esx_vi.c;h=f7eeeb5c5... What does it mean? The reporter also said they could do some (frankly voodoo) moving guests around and then the error went away. We're not sure if that was just coincidence.
