[PATCH 1/5] conf: Enforce SCSI hostdev address type

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If a SCSI subsystem <hostdev> element is provided with an <address>,
then enforce that the address type is 'drive'.  If not provided,
a 'drive' element was created by virDomainHostdevAssignAddress
which uses VIR_DOMAIN_DEVICE_ADDRESS_TYPE_DRIVE.
