[one-users] RVM in OpenNebula

[Rangababu Chakravarthula]

The thing is even after we manually update the host_shares table and set RVM
to 0, after couple of minutes again the values get updated.
When I track down the source, I see SchedulerVirtualMachine.cc &
LifeCycleActions.cc calling host->add_capacity host->del_capacity which in
turn calling HostShare
Where is the scheduler looking at when it is updating the HostShare table?
