[one-users] How to definitely remove CDROM image from a VM after installation

[ML mail]

Hi Carlos,

I understand that the "cloud-way" to go would be to have a contextualized image which I would upload and then instantiate instead of manually installing a VM like I did.

Which best-practice deployment would you suggest for more permament VMs? Would you instantiate a non-persistant OS image and have a persistent datablock for the data? (I think that is the classical way) What about the configuration files? Let's say I would have MySQL data on the datablock but then my MySQL configuration would be stored on the non-persistant image which could be a problem if I undeploy my VM by error. 

Regards,
M.L.

Hi,

For some things OpenNebula is more oriented to disposable VMs. In this case, you need to save the disks you want to preserve, shutdown the VM, and create a new VM Template (or edit the existing one) without the cdrom and context disks.

Now that I have installed Fedora I would like to permanently remove the cdrom image from my VM storage. I tried from Sunstone to detach it while running the VM but this fails as it is on the IDE bus (hdb).
