[one-users] VM monitoring information do not get deleted

[Ruben S. Montero]

Hi

I confirm the bug, it was introduced to address "Feature #2848: Add a
configuration flag to enable individual VM monitoring".

By default VM monitoring is disable to prevent a tsunami of pro-active VM
monitoring requests in case of massive failure of hypervisors. In that
situation OpenNebula would try to contact the VMs collapsing the drivers
and effectively blocking any other healthy hypervisor.

We are doing a maintenance release (4.6.1) next week, and this will be
solved. In the meantime you can either delete the vm_monitoring table, or
just set VM_INDIVIDUAL_MONITORING to "yes".

Thanks Wilma for the heads up.

Cheers

Ruben
