[one-users] ONE 2.0 underreporting running VM's in onehost list

[Carlos Martín Sánchez]

Hi Steve,

I assume you are using OpenNebula 2.2.

The host_shares contains the "running_vms" column; you need to update that
column value with OpenNebula stopped.

We are still trying to figure out what causes this bug, so if you come
across it again, it would be great if you could write down the operations
that led to it.

Regards.
