[libvirt] [PATCHv4 1/4] Allow LUN type disks to have no source

CD-ROMs and Floppies are allowed to have no source to imply they are empty or disconnected. Since the LUN type is used for raw CD-ROM access with QEMU (and VMWare in the future), it also needs to allow an empty source when the raw CD-ROM device is disconnected from the domain. --- src/conf/domain_conf.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index aed2a9d..a9ff61c 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -5218,9 +5218,11 @@ virDomainDiskDefParseXML(virDomainXMLOptionPtr xmlopt, } /* Only CDROM and Floppy devices are allowed missing source path - * to indicate no media present */ + * to indicate no media present.
