Re: [one-users] how to predeploy image
Hi Carlos, Thanks for help. I modified tm_clone.sh and it is working fine now. I am enclosing below the part of the script which was modified (from 43th line).

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.

I want to predeploy an image so that the VM could start at the scheduled by haizea time. How can I predeploy a VM's image? I would appreciate clarification. I had several ideas how to make it work but I didn't succeed. 1. I tried to copy a prepared image to the default directory (/var/lib/one/VM-id/images/) in which it should be stored when a new VM is created. 2. Then I tried to do the same and to create transfer.0.prolog file (after reading one of the generated by opennebula) but it didn't work. 3. I tried even set the source in DISK section in VM template to the copied file in the destination. However, everytime I can see in VM log, that the image is copied.
