Hum, looking at the current code now I see
.poolOptions = {
.flags = VIR_STORAGE_BACKEND_POOL_SOURCE_NAME,
.formatFromString = virStorageBackendLogicalPoolFormatFromString,
So there is an initialization of the field. It's unclear to me if
the two should be OR'ed, or should be kept as-is, if we have the pool
name do we need to provide the pool device then ? I get a bit confused
now.

Whoops !! :-)
That one applied cleanly.
So at least I'm commiting this part.
thanks !
