ok, Itamar,  thanks.

now I can understand how the things work.

but I have a question based on the fact that  I have ovirt-engine on
version 3.4  and DC and Cluster both are configured on version 3.3 :

- This means that I have available features on version 3.4 , but these
features just will work when I update DC and Cluster to version 3.4
?   (this is what I understand, following  Dafna Ron response)

so, to really obtain the benefits of the new version (3.4)  I need to
run the commands (yum update ovirt-engine-setup, engine-setup) and also
increase the version of compatibility within the datacenter, cluster and
host to the version 3.4


- and what I have if only update ovirt-engine  to version 3.4 and not
update dc, cluster neither hosts.
I realized changes on ovirt web admin interface,  improvements on icons
and maybe new fields.



some features in the engine do not require anything from 
hosts/cluster/DC, so you get them without upgrading the hosts/clusters/dc's.


for features that require an upgraded host/cluster/dc, you will only get 
them when you upgrade them accordingly.
(if you upgrade a cluster, features which are not DC level, will start 
being available post cluster upgrade, etc.)

I would like to understand what means all these versions, the same

all my doubts together :
What means datacenter in version 3.3(or lower version) when
ovirt is 3.4  ?
what means cluster in version 3.3 when ovirt is 3.4?
what means change the compatibility version for datacenter?

Gianluca replied with links for specific features.
I'll reply on the general concept:
- a host can be upgraded to a specific 3.x version. it can be in any
   3.y cluster which is = 3.x
   once the host is upgraded, 3.x host-level features can be used
- a cluster can be upgraded to 3.x once all active hosts in it are at
   least with 3.x.
   once the cluster is upgraded, 3.x cluster-level features can be used
- a data cetner can be upgaeded to 3.x once all clusters in it are at
   least with 3.x
   once the DC is upgraded, 3.x DC-level features can be used

i don't think we have it clearly documented per feture if it is host
level, cluster level or DC level. when in doubt, ask...

Re: [ovirt-users] compatibility relationship between datacenter, ovirt and cluster

2014-04-11 Thread Dafna Ron

you should look at the feature page.
if you do not fully upgrade cpu/data center you simply continue to work 
with 3.3 features

For oVirt I only found 3.0 features page (adapted form RHEV itself..) here:
http://www.ovirt.org/OVirt_3.0_Feature_Guide

It is quite generic.
Also I found release notes for 3.x, but not for 3.4 yet, at least from
page http://www.ovirt.org/Documentation

Can anyone add this link to it?
http://www.ovirt.org/OVirt_3.4_Release_Notes

I can do it, but I'm not a maintainer... and this is the main
page... let me know if you wish me to do.

You can also follow RHEV documents, tough its versions are not
completely aligned with oVirt versions.

To get information about clusters and DataCenters compatibility version:

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.3/html/Administration_Guide/sect-Post-upgrade_Tasks.html

Regarding the features:
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.3/html/Administration_Guide/sect-Post-upgrade_Tasks.html#Features_Requiring_a_Comparability_Upgrade_to_Red_Hat_Enterprise_Virtualization_3.3

Similar pages for RHEV 3.4 beta, but I don't know their degree of
consistency at this time.

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.4-Beta/html/Administration_Guide/sect-Post-upgrade_Tasks.html

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.4-Beta/html/Administration_Guide/Features_Requiring_a_Compatibility_Upgrade_to_Red_Hat_Enterprise_Virtualization_3.4.html
