[libvirt] [PATCH 3/5] VMX: Add support for 'auto detect' fileNames

[Doug Goldstein]

VMWare Fusion 5 can set the CD-ROM's file name to be 'auto detect' when
using the physical drive via 'cdrom-raw' device type. VMWare will then
connect to first available host CD-ROM to the virtual machine upon start
up according to VMWare documentation.
