Hi,
We're running oVirt 4.0.4.4 with engine python SDK version 3.6.7, and
currently we're developing an application that first creates a VmPool
and afterwards it updates it. However, sometimes happens that both
operations occur at the same time, which results in an oVirt error
claiming that a VmPool cannot be updated if there are still pending
operations to do.
We want to control this situation, so we've checked if the VmPool class
has a .get_status() method but it seems it doesn't, so I'm asking for
alternative ways of handling this. Would it be enough to say a VmPool is
not "busy" if all its VMs are not in a blocked state (for example, with
a blocked disk due to clonation)?
Thanks.

You are right, there is no "status" attribute in VM pools, the only way
to check if the pool is busy is as you suggest.
I take the opportunity to remind you that we will drop version 3 of the
API and version 3 of the SDKs in oVirt 4.2. Consider switching to versin
4 of the API and version 4 of the SDK. There are documentation and
examples here:
https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk
https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk/examples
Also, when checking what attributes are available in the API you can use
the documentation that is included in the system itself. For example, to
see the attributes of the "vm_pool" type you can go here:
https://myengine.example.com/ovirt-engine/api/model#types/vm_pool
