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
Thanks,
Gianluca
