Tal Nisan has submitted this change and it was merged. Change subject: core: fix inconsistency with empty cd-rom value ...................................................................... core: fix inconsistency with empty cd-rom value By default, the CD-ROM attached to the VM is NULL. VDSM also reports NULL value in case no CD-ROM is attached. Recently RunVmCommand was changed to persist the CD-ROM that is attached to a VM as well, however, it is then set to an empty string if no CD-ROM is attached. Therefore, the monitoring gets empty string from the DB and NULL value from VDSM and decides to update VM dynamic data because of this change. But later on, the NULL value from VDSM is ignored and thus, this flow will happen on every monitoring cycle, leading to many redundant updates of VM dynamic daa.
