Hello,
in recent versions of oVirt (eg my last 4.4.10) there is the feature to make a clone of a running VM.
This operation passes through a temporary VM snapshot (then automatically deleted) and cloning of this snapshot.
For the most part, yes (we now skip the creation of the snapshot when the VM uses MBS disks)
Sometimes there is a need to clone a VM but only a subset of its disks is required (eg in my case I want to retain boot disk, 20Gb, and dedicated sw disk, 20Gb, but not data disk, that usually is big... in my case 200Gb).
In this scenario I have to go the old path where I explicitly create a snapshot of the VM, where I can select a subset of the disks, then I clone the snapshot and last I delete the snapshot.
Do you think it is interesting to have the option of selecting disks when you clone a running VM and go automatic..?
If I want to open a bugzilla as RFE, what components and options I have to select?
The initial idea behind clone-VM was to have a simple operation for getting an exact-clone (sure, with different ID, different MAC addresses and so on) of an existing VM without going through the cycle you mentioned of: creating a snapshot, cloning a VM from the snapshot and removing the snapshot
While external contributions for adding the ability to filter the disks of the cloned VM would be welcome, it's unlikely to be something we would get to since there is an alternative way to achieve this and it's not considered to be a common scenario
