[one-users] how to predeploy image

Wed Apr 13 01:28:37 PDT 2011

Hi Łukasz,

You could use the tm_dummy driver. That tm script returns always 0 and does
nothing else.
But using that tm_driver, you will have to manually move the files for all
VMs, not just some of them.

It would be best if you could modify the driver (tm_clone.sh, look for it in
your lib location) to issue the mkdir and scp commands only if the
destination file is not already present. It should be pretty
straight-forward.

Regards,
Carlos.
