Title: RE: [Condor-users] "vm_cdrom_files = a, b, c" : How does this work?

Yes. Condor creates a .iso file. VM (.vmx file) is also configured automatically with .iso file as CDROM. So, OS in VM will see the CDROM.

.iso file is created on the execute node on the fly.

If it is not working as expected, check logs like VMGahpLog.

Hi,

I have a pool of WIndows XP Condor pool PCs, which have VMware 1.0.6 installed.

I want to submit a condor job as a VMware image with a linux OS (ttyLinux).

I'd like to use this feature of "vm_cdrom_files = ...", but I don't understand how this works.
The manual says:

---- quote --------------

A CD-ROM for the virtual machine is composed of a set of files.
These files are specified in the submit description file
with a comma-separated list of file names.
  vm_cdrom_files = a.txt,b.txt,c.txt

If these files are not on a shared file system visible to
the machine that will run the vm universe job, then
Condor must also be told to transfer them from
the submit machine with
  vm_should_transfer_cdrom_files = YES
---- end-quote -------------
Basic questions I have are:

* How do I set up the configuration of the CD-Rom in the VMware virtual machine?

* Once the virtual linux system is up and running, how can it access the cdrom files?
Should it mount the CD-Rom? On the linux system, the boot message has:
          hda: VMware Virtual IDE Hard Drive, ATA DISK drive
          hdb: VMware Virtual IDE CDROM Drive, ATAPI CD/DVD-ROM drive
Should I then do "mount -t iso6990 /dev/hdb /mnt/cdrom" to access the condor cdrom files?
I've tried this, but it doesn't seem to work......
If condor wraps these files into an iso image (does it?), then how can I tell the VMware
configuration to use a not-yet-existing iso image for the CDrom???

Thank you!

Rob.
