[one-users] poll script return value if VM is not running

[Carlos Martín Sánchez]

Hi Nikolay,

The core looks for those meaningful attributes and updates them only if they
are present and not equal to '-1', but they are not mandatory.
If any of them is not found, the previous value persist.

I would say that your driver should return all values that can be retrieved
from the hypervisor.


Regards.
