Thu Sep 22 20:35:04 UTC 2011
Focusing on guest disk devices.
* src/conf/domain_conf.c (virDomainDiskDefFormat)
(virDomainControllerDefFormat, virDomainLeaseDefFormat)
(virDomainFSDefFormat): Add parameter.
(virDomainDefFormatInternal): Adjust caller.
* src/conf/storage_encryption_conf.c (virStorageEncryptionFormat):
Simplify.
