Hi Nicolas,

it does sound like a bug, ballooning shouldn’t be disabled in this case.

does it behave the same in GUI?

Thanks,

Hi,

We're using oVirt 4.3.8 along with ovirt-engine-sdk-python (4.4.1) to handle our pools.

Pools are based on a template which has ballooning enabled. However, when deploying a VmPool based on that template, has the "Ballooning enabled" field disabled, uneditable and an icon which states: "The field is not attached to any instance type" (screenshot attached).

We're handling a big number of VMs based on pools (> 1500), and we think this should be enabled.

However, I don't see a field in the types.VmPool definition that allows that.

Is that even doable? Our Python code is similar to this:

newpool = types.VmPool(name='test',
                                         cluster=cl,
                                         template=t,
                                         max_user_vms=1,
                                         size=1,
                                         type=types.VmPoolType.MANUAL)
vmpool_serv.add(newpool)

• cl is a types.Cluster instance with ballooning_enabled=True
• t is a types.Template instance with Ballooning enabled.

Thanks.

Nico
