Hi all,
I'm new to Ovirt coming from a OVM ( aka Xen ) environment and I'm
trying to work out how to do similar things.
In my OVM environment I have VMs that are 100GB in size. These VMs are
templates that are used for running customer workshops so we create and
destroy them quite often.
In OVM I can clone 10 x 100GB VM's in about 1 minute, the cloning
process just creates a "delta" VM rather than copying the entire 100GB.
Those VM's can then be run and the on-disk size of the delta VM grows as
it runs and deviates from the master.
The same goes for templates, creating a 100GB VM from a template takes
only a few seconds. Creating a template from a VM only takes a few seconds.
My problem is that I cant seem to do any of this using Ovirt.
it appears that there is no way to tell the cloning process " I want 10"
like I can in OVM - am I missing something here?
In my tests I find that even if a "snapshot" is made, the entire VM is
copied rather than creating a delta.
Creating a VM from a template is no different in that it copies the
entire VM.
So...
Is it possible for Ovirt to create multiple clones on request ?
Can Ovirt do "delta" copies rather than copy the entire VM ?
If Ovirt can do these things, how do I set it up to to do that ?
Any help appreciated.
thanks
Tim
