using CD-ROM on the client?

Hi:

I am running GSX3.1 on SLES 9 host. A windows XP VM has been configured to use CD-ROM on client as Auto detect. CD-ROM is not connected at power on.

Remote console is installed on a physical windows XP client.

From GSX admin guide, it stated that if the user has R+X permission on the VM configuration file, the user should be able to interact with the VM: change its power state (power it on or off,suspend or resume it) and connect or disconnect removable devices.

But I got "There is a problem saving your changes. Permission denied!"

Using the owner of the VM, I can connect to the CD-ROM on the client while the VM is running.

What kind of permission should I set for the user to be able to do so?

Thanks,
