[one-users] option to prevent a VM instance from being deployed

[Simon Boulet]

Hi,

I have just submitted a patch that solves this.

http://dev.opennebula.org/issues/1103

You could use that patch along with a custom CREATE VM HOOK that checks for
a custom VM attribute you specify in your templates.

Feedback more than welcome!

Thanks

Simon
