Are you missing the '#include "datatypes.h"' header ?
Yes, that was indeed the fix.
Although, in the meantime I found:
virSecretPtr secret;
secret = virSecretLookupByUUIDString(conn,
pool->def->source.auth.cephx.secret);
value = virSecretGetValue(secret, &value_size, 0);
This also works fine, but what do you recommend?
