Version of engine vs version of host
by Gianluca Cecchi 16 Jun '17

16 Jun '17

Hello, between problems solved in upcoming 4.1.3 release I see this: Lost Connection After Host Deploy when 4.1.3 Host Added to 4.1.2 Engine tracked by https://bugzilla.redhat.com/show_bug.cgi?id=1459484 As a matter of principle I would prefer to force that an engine version must be greater or equal than all the hosts it is intended to manage. I don't find safe to allow this and probably unnecessary maintenance work... what do you think? For example if you go here: http://www.vmware.com/resources/compatibility/sim/interop_matrix.php#intero… you can see that: - a vCenter Server 5.0U3 cannot manage an ESXi 5.1 host - a vCenter Server 5.1U3 cannot manage an ESXi 6.0 host - a vCenter Server 6.0U3 cannot manage an ESXi 6.5 host In my opinion an administrator of the virtual infrastructure doesn't expect to be able to manage newer versions' hosts with older engines... and probably he/she doesn't feel this feature as a value added. Just my thoughts. Cheers, Gianluca

ovirt sdk and pipelining
by Fabrice Bacchella 16 Jun '17

16 Jun '17

I just read the blog entry about performance increate in for the python sdk (https://www.ovirt.org/blog/2017/05/higher-performance-for-python-sdk/) I'm quite sceptical about pipelining. A few explanation about that can be found at: https://devcentral.f5.com/articles/http-pipelining-a-security-risk-without-… https://stackoverflow.com/questions/14810890/what-are-the-disadvantages-of-… It also talks about multiple connection, but don't use pycurl.CurlShare(). I thing this might be very helpfull, as it allows to share cookies, see https://curl.haxx.se/libcurl/c/CURLOPT_SHARE.html.

Hosted engine
by Joel Diaz 15 Jun '17

15 Jun '17

Good morning oVirt community, I'm running a three host gluster environment with hosted engine. Yesterday the engine went down and has not been able to come up properly. It tries to start on all three host. I have two gluster volumes, data and engne. The data storage domian volume is no longer mounted but the engine volume is up. I've restarted the gluster service and make sure both volumes were running. The data volume will not mount. How can I get the engine running properly again? Thanks, Joel

quick question on hosted engine storage
by cmc 15 Jun '17

15 Jun '17

Hi, When building a hosted engine VM, and choosing 'nfs' for storage, it does the install to this nfs share. Once the host is setup with, e.g., fibre channel as storage for VMs, does the hosted engine get migrated automatically to this storage? When does this actually happen? Thanks, Cam

oVirt storage best practise
by Stefano Bovina 15 Jun '17

15 Jun '17

Hi, does a storage best practise document for oVirt exist? Some examples: oVirt allows to extend an existing storage domain: Is it better to keep a 1:1 relation between LUN and oVirt storage domain? If not, is it better to avoid adding LUNs to an already existing storage domain? Following the previous questions: Is it better to have 1 Big oVirt storage domain or many small oVirt storage domains? There is a max num VM/disks for storage domain? In which case is it better to use "direct attached lun" with respect to an image on an oVirt storage domain? Example: Simple web server: ----> image Large database (simple example): - root,swap etc: 30GB ----> image? - data disk: 500GB -----> (direct or image?) Regards, Stefano

oVirt and Cloud-Init
by Adam Mills 15 Jun '17

15 Jun '17

Hello oVirt Users! Recent the team that I work on began investigating oVirt as a virtualization platform. It is extremely promising, however we have some questions about how oVirt does provisioning using Cloud-Init. Specifically the question is: On the wiki the it states "We are most interested in using config-drive version 2 [2], which is also in supported by OpenStack". Is that currently how Cloud-Init is providing the datasource to the machine is via a config-drive being mounted? And the last question: How frequent is too frequent to ask questions to this mailing group :D --- - name: Adam Mills title: Network Engineer

oVirt: 3rd party support
by ovirt＠fateknollogee.com 13 Jun '17

13 Jun '17

Are there any shops or folks on this list that provide 3rd party support for oVirt? Support via email, remote login or phone/skype etc? Not looking for or asking about free support.

Migrating oVirt cluster from 4.0 to 4.1
by James 13 Jun '17

13 Jun '17

We recently moved our oVirt cluster from 4.0 to 4.1 and have migrated all the hosts. The datacenter currently has a compatability setting of 4.1 but the cluster is still on 4.0. As cross-cluster migrations has been removed (no option anymore?) we aren't 100% sure how to get the cluster onto 4.1 whilst keeping the VMs online. Do we just change the compatibility version live and it "just works" or do we have to have downtime? Any info would be great! Regards, James
