oVirt node 4.3.4 stable can't deploy hosted engine to iscsi target all available LUNs used
by Mitja Pirih
Hi,
I am new to oVirt, coming from XenServer platform, so please be patient with me.
After a successful install of latest stable oVirt node (ovirt-node-ng-installer-4.3.4-2019061016.el7.iso) I am having troubles deploying hosted engine to an iscsi target over Cockpit. I have a couple of iscsi targets available on two different storage platforms (Synology DS418, Lenovo DE2000H). After retrieving iscsi Target list all LUNs get automatically "connected" by "Target list scan" and shown as used on LUNs list. I can reproduce this every single time. On storage system I can also see, that all LUNs get connected by the initial scan. As a result I an unable to continue the deployment as there are no LUNs available.
Is this a normal behavior? What would you suggest me to do?
Thanks.

Adding a custom fence agent on 4.3.4
by Matteo
Hi,
I'm trying to add a custom fence agent for my test deployment on hetzner.
Have written a small fence_hetzner_robot script which works ok from cli and installed on every ovirt node.
Then added with engine_config in this way:
# engine-config -s CustomVdsFenceType="hetzner_robot"
But does not show up in fence agents list under host pm configuration.
I'm missing something?
thanks!
Matteo
PS:
Also tried to set up an empty param mapping, just to test
# engine-config -s CustomVdsFenceOptionMapping="hetzner_robot:"
but still nothing.

SPICE and VNC native
by kim.kargaard＠noroff.no
Hi,
We are running ovirt 4.3. The engine is on a bare metal machine and the hosts are running on Centos 7. When installing the engine, I set it to be the webproxy. When I create a new vm, I select both SPICE+VNC. When clicking on the console I only have the option for SPICE native, not for the HTML option. For VNC I have both options and the HTML option can be selected and works. But, this is also the only option that works. VNC Native as well as SPICE Native do not work. I have tried using both remote viewer on Mac and a VNC client on a Windows machine and neither will actually open the VM. I would really also like the SPICE HTML option to exist, but it does not. The enable SPICE proxy in the Console selection is greyed out.
When I open in remoteviewer (Mac) I get Unable to connect to the graphic server.
Any suggestions?

it seems vgpu state be mistack freed when operating(start and stop) vm at the same time
by weizhengya16＠gmail.com
We using ovirt in production environment with each virtual machine with a vGpu。but serveral days later, I find several phisical server has been crash and automatic reboot。And I also found some vGpu exist with no virtual machine using. So it makes virtual machine start fail because of lacking resource.I must enter the vgpu directory and using "echo "1" >remove" to free this vGpu。With ceaselessly stop and start, the probability of its occurrence is approximately 0.1%-1%

Failed on HE-Storage migration
by Christoph Köhler
Hello,
we tried to migrate the hosted engine to a new storage but we ran into
an error - in any attempt the same.
What we did is:
° Version 4.3.4.3-1.el7
° in the engine vm: systemctl stop ovirt-engine
° took backup with scope=all
° hosted-engine --set-maintenance --mode=global
° hosted-engine --vm-shutdown
° on a new host (not in the inventory of engineDB): hosted-engine
---deploy --restore-from-file=backup-file
It ran fine until:

I've restarted the engine host. I've restarted the engine service. I've checked for zombie tasks with the db utils - none found.
Engine is hosted in a HA environment with 2 iron boxes, I have rebooted the hosts that engine is running on. I have migrated hostedengine to both hosts to see if there's an issue perhaps with one of the hosts. No resolution of issue.
Been searching for various aspects of the logs to try & get an answer (for quite a few days this issue started some time ago and is in our test environment), all seem to lead to dead ends.

Last thing I did before this error showed up was created about 10 servers from a template. There were various lease errors for the servers but they came up and seemed functional. Clearly the issue is here: "Exception in startFailedAutoStartVms" in the "START_ARRAY token" but I can't find anything as of yet that says if you see this - do x,y,z.
Learning oVirt so my apologies if this is a 101 question.

Re: SPICE and VNC native
by Strahil
The graphics server is the actual host.
Can you directly access SPICE/VNC port from your workstation?
