| Hi,
| 
| I would like to see a more advanced type of Power-Saving Cluster policy,
| where an empty Host gets put into a sleep-mode, so that it draws as little
| power as possible and can be awoken by engine when VM's starts to use more
| resources.
| 
| A typical scenario would be that all VM's are spread evenly over Hosts during
| day-time, when customers are actively using their VM's. But then during
| off-hours, VM's gets clumped up into maybe one or two Hosts, and the other
| Hosts can be put to sleep to save energy, and then woken up in the morning
| again.

Hi Karli,
this should be achievable for you in 3.3 with some minor work on your side;
In oVirt 3.3 we introduce the new scheduler, which allows you to run your own
code when doing VM placement and load balancing.

You can write your own load balancing logic replacing the built-in one,
which will switch to power saving at a given time. Once a host has no
running VMs, your balance logic can switch it into S3 state (sleep), and
when needed or in a given time use wake-on-lan to resume all suspended hosts.

If you want we can guide you through it post 3.3 release.

| earlier in the year we did a survey for feature requests / improvements
| / etc.
| 
| since a lot of things were added, and priorities usually change, I'd
| like to ask again for "what do you need the most from oVirt / what are
| your pain points" next?
| 
| below[1] I've listed my understanding of what already went in from
| previous survey requests (to various degrees of coverage).
| 
| Thanks,
|     Itamar
| 
| [1] from the top 12
| V Allow disk resize
| V Integrate Nagios/Zabbix monitoring - via a ui plugin
| V Highly Available engine - via hosted engine[2]
| V Open vSwitch integration - via neutron integration
| X Allow cloning VMs without template
| ? Enable hypervisor upgrade/updates through engine[3]
| V Allow engine on an oVirt hosted VM - via hosted engine[2]
| V Enable guest configuration (root password, SSH keys, network) via
|    guest agent in engine - via cloud-init
| X Integrate v2v into engine
| ? Bond/extend ovirtmgmt with a second network for HA/increased
|    bandwidth[4]
| X Integrate scheduling of snapshots and VM export for backups in
|    engine[5]
| V Spice – support Google Chrome - via mime based launch
| 
| 
| Other items mentioned in previous survey which should be covered by now:
| - Fix timeout when adding local host during all-in-one configuration
| - Fix engine set-up when SELinux is disabled
| - Provide packages for el6 (CentOS, Red Hat Enterprise Linux)
| - Allow multiple VMs to be deployed from the same template at the same
|    time
| - ISO domains on local/GlusterS
| - Show IP addresses in Virtual Machines->Network Interfaces
| - OpenStack Quantum support (now called Neutron)
| - noVNC support
| - Support spice.html5 and websocket proxy
| - Add other guest OSes to list
| - Port oVirt guest agent to Ubuntu[6]
| - SLA - Allow resource time-sharing
| - Spice - Mac client (via mime based launch)
| - Spice - port XPI plug-in to Windows (not sure this will happen, but
|    mime based launch allows using firefox now)
| - Spice - client for Ubuntu/Debian (should be covered via mime based
|    launch)
| 
| 
| [2] hosted engine is in active development, but not released yet.
| [3] host update is supported, but not for general yum update.
| [4] a lot of improvements were done in this space, but i'm not sure if
|      they cover this exact use case
| [5] backup api is now being pushed to master, and orchestration of
|      backups should probably happen via 3rd part backup vendors?
| [6] I'm not sure packaging exists yet, but ubuntu is covered for the
|      basic functionality of the guest agent.
