Define "restore an engine" and "dump file". Assuming "restore an engine" means "Install a fresh OS+engine and make it behave like an old one", and "dump file" being a pg_dump dump file, the answer is "not easily, and not fully". You will have to do something like: 1. Install OS+engine 2. Manually provision PG (init, create user/db, etc) 3. Restore your dump (pg_restore or psql, depending on format). Use the user you created, not postgres, for restoring - this will have much better chances to get permissions right 4. Run engine-setup and provide it the credentials of the database you restored It should mostly work, and I heard about people doing that, although didn't try this myself. Notably, you will have to reinstall all your hosts (move to maintenance, reinstall). If you have also a backup of /etc, that's a different case. Then, you can selectively restore files there before engine-setup. To see a list of the files you should restore, check the source of the engine-backup script - it has an internal variable called 'BACKUP_PATHS'. Good luck and best regards, -- Didi

VM migrations failing after upgrade 4.3.2 -> 4.3.3
by Eduardo Mayoral 17 Apr '19

Hi, After upgrade to 4.3.3 from 4.3.2, VM migrations are failing with "No available host to migrate VMs to" Interestingly, this happens in one of our clusters, not on the other. Both on the same datacenter, both in 4.3 compatibility version. This are the relevant lines from /var/log/ovirt-engine/engine.log 2019-04-17 08:58:41,816Z ERROR [org.ovirt.engine.core.bll.GetValidHostsForVmsQuery] (default task-7)

Inconsistencies beteween WebUI, API read verbs and API write verbs
by Baptiste Agasse 17 Apr '19

17 Apr '19

Hi All, As I stated in a previous thread, we use instances types and wanted to automate some parts to manage it [1]. Thansk to ovirt-orb/lago and pointers given in the last thread, I'm working on ansible an module to manage ovirt instance types, but I'm facing some troubles for some of instance type attributes. From the API, I don't have access to all fields provided via WebUI (eg: Custom Emulated Machine), and it seems that some fields can be added/updated via the API but are not part of the response when you read an instance type (eg: VirtIO-SCSI Enabled). Provided examples are not exhaustive. I tried to find my way in the oVirt engine code-base to see if the fix will be easy for a non java developer like me. I find, I think, that it seems to be some API definitions for instance type [2] that define, if I understand it well, all verbs that can be applied to each resource and what field can be put when adding an instance type, but nothing about fields to be included when you read a resource (and I'm not sure if its related to v4 API). I find also some java code [3] [4] that seems related to this but As I'm not a java developer, its a little bit difficult for me to find my path in it. For me this inconsistencies are a bug, but as you stated that instance types are in deep maintenance mode, do you think that bug will get some attention ? My objective is to have a ansible module that manage the hardware/bios related stuff (memory, boot sequence, scsi controller, bios type, almost all the things) and HA for instance type. Have a nice day. Cheers.

oVirt nVidia vGPU driver questions
by femi adegoke 17 Apr '19

17 Apr '19

I'm on oVirt 4.2.6. 1) If I have a Tesla P4 (Pascal) GPU (non-GRID), do I use nVidia vGPU driver for RHEL KVM 6.2 or the Linux KVM vGPU 6.2 driver? 2) If I have a Grid K1 or K2, I assume the correct driver would be GRID 4.7? 3) Must the vGPU driver be installed on the host & in the vm? 4) Must the vGPU driver be installed first before I can run "yum -y install vdsm-hook-vfio-mdev”

Gluster suggestions
by Magnus Isaksson 16 Apr '19

16 Apr '19

Hello I would like some suggestions on what type of solution with Gluster i should use. I have 4 hosts with 3 disks each, i want to user as much space as possible but also some redundancy, like raid5 or 6 The 4 hosts are running oVirt on CentOS 7 I have 2 clusters due to some licensing issues, so i cant use ovirts setup of gluster Today i have set it up as follows Type: Disperse Number of Bricks: 1 x (8 + 4) = 12 So i have 3 bricks per host (one brick per disk) But this setup is not working very well, as soon as i get some traffic on the volume this start to fail on the ovirt nodes, loosing connection etc. All hosts are connected via 10G interface So any suggestions on how i would set this up as best is much appreciated. Regards Magnus Isaksson
