Hello,
It seems ovirt API lacks of possibility to define storage domain, in which =
cloned vm (from snapshot) will be created, is it done on purpose, or it is =
just missing/under development ?
Scenario using WEB GUI :
Create snapshot of any running VM, right-click on snapshot, select =93clone=
=94
In pop-up window you can enter new VM name etc, under =93resource allocatio=
n=94 section *you can select where it will be created*
Scenario using python-sdk/ovirt-api
I was trying to create vm for example like this:
##
vm_params =3D params.VM(name=3Dvm_from_list + '__bak', cluster=3Dapi.cluste=
rs.get("Default"), storage_domain=3Dapi.storagedomains.get("temp"),
memory=
=3Dvm.get_memory(), snapshots=3Dsnapshots_param)
api.vms.add(vm_params)
##
# temp is =84other=93 storage domain, NFS v3
VM will be still created on same storage as original VM, no matter what dom=
ain I will define in params...
Also tried other variations, using templates, disk profiles and so on, but =
nothing has changed where new VM is created.
I know cloning is not intended for backup purpose, but it is workaround pro=
bably half of Ovirt users use.
In my case, it is not very smart to do snapshot and create VM (allocate dis=
k space, etc) on same storage domain where there is already running a lot o=
f VMs, environment is already busy.
Thanks !

Thank you, this was the solution,
Modified version of original script available here: http://pastebin.com/GEtSJMCN
Original : https://github.com/wefixit-AT/oVirtBackup
Diff: moded version is doing backup for all running VMS in cluster, trying to clone VM
into different storage domain (avoiding load on main domain)
Please remove "iterration" if statement, I was using it to stop script from
doing backup for all VMs (testing)

Hi,
if you have issues or improvements please post this on github to improve
the backup tool.
