   if you keep the cdrom_files and if you include below two lines into 
the submit description
file. once the job is submitted to a machine these file also will be 
copied and there it is converted
into an iso file and attached to the VM. If only the cdrom_device found 
for that VM while condor
creating the its own vmx file.

   Make sure your vmx file contains these lines. In order to condor 
detect and set cdrom_device.

   ide1:0.present = "TRUE"
   ide1:0.deviceType = "atapi-cdrom" or "cdrom-raw"
   ide1:0.autodetect = "TRUE"

   yes you have to mount.
   I use "mount /dev/cdrom /mnt/cdrom".

may be the cd_rom is not pointing to the iso files.

   once vm is started check the condor created vmx i.e 
(vmXXXXXX_condor.vmx) file it should be like these
if it is attached iso file.

   ide1:0.present = "TRUE"
   ide1:0.fileName = "isoHVKf1E.iso"
   de1:0.deviceType = "cdrom-image"
   ide1:0.autodetect = "TRUE"

   yes, condor wraps these files into iso. you no need to specify any 
iso condor creates
and attach to the VMware through the vmx file it creating, in that you 
can check.

I am using pool of linux machine and using vmware 1.0.4.
