[one-users] Memory on Host

[Javier Fontan]

Hello,

OpenNebula periodically gets information about hosts, you can change
the time between polls in oned.conf:

--8<------
#  HOST_MONITORING_INTERVAL: Time in seconds between host monitorization
HOST_MONITORING_INTERVAL = 60
------>8--

Can you tell me the hypervisor you are using so I can take a look on
how memory values are retrieved.

Bye
