iscsi or iser targets are not detached from the host in the maintenance mode
by Arman Khalatyan 16 Feb '17

16 Feb '17

Hi, In ovirt 4.1 when I put the host into maintenance mode then the nfs mounts are unmounted as expected. but the hosts are still logged into the targets. Is it expected behavior?? If yes what is the use of it? Another thing concerning to the permanently removed direct LUNs. They are still in the /var/lib/iscsi/nodes and /var/lib/iscsi/send_targets/* Would be good to cleanup the folders if users are removing permanently the LUNs. Thanks, Arman.

vdsm conf files sync
by Gianluca Cecchi 16 Feb '17

16 Feb '17

Hello, in my 2 original 4.1 hosts I got some storage errors using rdbms machines when restoring or doing hevy I/O. My storage domain is FC SAN based. I solved the problem setting this conservative settings into /etc/vdsm/vdsm.conf.d cat 50_thin_block_extension_rules.conf [irs] # Together with volume_utilization_chunk_mb, set the minimal free # space before a thin provisioned block volume is extended. Use lower # values to extend earlier. volume_utilization_percent = 25 # Size of extension chunk in megabytes, and together with # volume_utilization_percent, set the free space limit. Use higher # values to extend in bigger chunks. volume_utilization_chunk_mb = 4096 Then I added a third host in a second time and I wrongly supposed that an equal vdsm configurtion would have been deployed with "New Host" from gui.... But is not so. Yesterday with a VM running on this third hypervisor I got the previous experimented messages; some cycles of these VM dbatest6 has recovered from paused back to up. VM dbatest6 has been paused due to no Storage space error. VM dbatest6 has been paused. in a 2 hours period. Two questions: - why not align hypervisor configuration when adding host and in particular the vdsm one? Any reason in general for having different config in hosts of the same cluster? - the host that was running the VM was not the SPM. Who is in charge of applying the settings about volume extension when a VM I/O load requires it because of a thin provisioned disk in use? I presume not the SPM but the host that has in charge the VM, based on what I saw yesterday... Thanks, Gianluca

Requirements to use ovirt-image-repository
by Gianluca Cecchi 16 Feb '17

16 Feb '17

Hello, is it sufficient to open outside glance port (9292) of glance.ovirt.org or is there anything else to do? Making a test from an environment without outside restrictions it seems that is only the engine that connects, correct? Thanks, Gianluca

Secure installation via RPM
by Michael Gauthier 16 Feb '17

16 Feb '17

Hello, The getting download documentation (http://www.ovirt.org/download/) says to use yum to install a RPM directly from a plain HTTP URL. Is there a HTTPS host for the oVirt RPMs? If not, is the RPM signed with a GPG key? Is the GPG signature available via HTTPS? Please see https://access.redhat.com/blogs/766093/posts/1976693 Thanks, Mike

Disaster Recovery Testing
by Gary Lloyd 16 Feb '17

16 Feb '17

Hi We currently use direct lun for our virtual machines and I would like to move away from doing this and move onto storage domains. At the moment we are using an ISCSI SAN and we use on replicas created on the SAN for disaster recovery. As a test I thought I would replicate an existing storage domain's volume (via the SAN) and try to mount again as a separate storage domain (This is with ovirt 4.06 (cluster mode 3.6)) I can log into the iscsi disk but then nothing gets listed under Storage Name / Storage ID (VG Name) Should this be possible or will it not work due the the uids being identical ? Many Thanks *Gary Lloyd* ________________________________________________ I.T.

Exporting VM as ova
by Benjamin Alfery 15 Feb '17

Hi, I'm using ovirt 4.0 and was wondering if it is possible to export an existing VM to ova format (via the gui). If it's not possible via GUI, is that possible at all? Best Regards Benjamin

How to enable Global Maintenance via the REST-API?
by Doug Ingham 15 Feb '17

15 Feb '17

Hey Guys, I've gone through both oVirt's & Red Hat's API docs, but I can only find info on getting the global maintenance state & setting local maintenance on specific hosts. Is it not possible to set global maintenance via the API? I'm writing up a new script for our engine-backup routine, but having to set GM by acessing a specific node seems a bit inelegant... https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/singl… Cheers, -- Doug

ovirt 4 reboot behaviour
by Giulio Casella 15 Feb '17

15 Feb '17

Hi, I noticed a different behaviour after upgrading my entire setup from rhev 3.6.9 to rhev 4.0.5. A virtual machine reboot changes the host where the VM is running, also if the VM was started in "run once" mode with a payload specifying a placement policy. In version 3 the VM didn't change host across a reboot; and continued running in run once mode, keeping the same payload given at start time. Is there a way to keep the VM running on the same host across a reboot, excluding the obvious (but time consuming) way of migration after reboot? If not (but this is a request for enhancement), is it possible to introduce a payload for reboot (just like for "start") to specify the placement policy? Thank you in advance, gc
