(e.g. call to virSecurityManagerCheckAllLabel also goes through ndisks)... Your comment below makes me wonder if there's anything else that got moved that may have assumed Translate had been run. Would make that virDomainDiskDefValidate less interesting if the Translate could be done during Init prior to Validate. My head/eyes hurt ACK to what's here though - just was trying to think out loud...
