(This statement assumes you're using VMWare ESX. If you're using GSX,
what I say may not apply.)

I rather suspect it has to do with the fact that the files containing
your VMs (*.dsk) are actually written onto a filesystem that is
formatted as VMFS. VMFS filesystems cannot be directly backed up with
the TSM client for Linux; the client does not support them.

The workaround is to use the virtualmountpoint parameter. So you would
want to back up everything else on the VMWare server under one nodename,
and create a second nodename for the *.dsk backups, and use the option

     virtualmountpoint <directory tree containing *.dsk files>

when you define the schedule that backs up only the VM files. Remember
also that your *.dsk files cannot be given a valid backup unless you
shut down the VM contained with the file; otherwise, the backups will
most likely be invalid.

There is a rumor running about that there will be TSM client support for
VMWare's .dsk files (while hot) in a future release of the client.
