oVirt reports using Grafana
by Karli Sjöberg
Heya!
I've been whishing for reports in oVirt ever since the old 'Jasper
Reports' was removed. For an Enterprise, having pretty graphs to look
at is a must.
Searching the subject, I've found this[*] and have managed to get it
installed OK but having issues trying to follow the guide setting it
up.
First of all, I think the guide should have at least mentioned that
'pg_hba.conf' needs to be edited for the read only user to be able to
connect to the database, I scratched my head around that for a while
before I got it.
When I first type in the query example, I got syntax errors:
'pq: syntax error at or near "$"'. I continued anyways since I figured
it would be solved at a later point, which turned out to be true, since
the next step is to use the "Templating feature" to add variables.
Unfortunately this doesn't go so well, even though I followed the
instructions very carefully. After hitting save on the first variable I
am rewarded with the error message:
'Template variables could not be initialized: pq: column "en_us" does
not exist.'
Are the queries stated in the guide still correct? This is for
'user_locale':
"SELECT DISTINCT language_code from enum_translator"

Changing resolution of console on Mint guest running on Ovirt 4.2

I keep getting an error: Could not set configuration for CRTC 63.
I checked that I have spice-agent and spice-agentd running. Also qemu-guest-agent. lspci shows that I have a QXL adapter. xrandr -q shows that I have many different config available. but none work.
What am I missing?

ovirt-node: freshly installed node: network interfaces not visible
by etienne.charlier＠reduspaceservices.eu
Hello,
I'm deploying a test cluster to get used to the ovirt product.
My ovirt ( 4.2.2) engine is deployed in a vmware virtual machine.
I'm busy deploying 5 hosts using the ovirt-node iso.
I have issue with the additional physical network interface ( used for vm trafic and iSCSI)
In ovirt manager I can't see the physical network interfaces. It's thus not possible to assign logical network to physical interfaces and my hosts stays in "non operational" status.
How should I configure the additional interfaces in the ovirt-node installer to have them recognized ?
I somehow managed to configure one host and I can see a comment line in /etc/sysconfig/network-script/ifcfg-... saying vdsm has acquired the interface....
No Such line in the ifcfg-* file in non operational hosts....
Any idea ?

vGPU setup guide
by Callum Smith
Dear All,
IS this the most current and useful example of implenting vGPUs in oVirt? I had understood that 4.2 had NVIDIA GRID support as a flagship feature, but this appears to be 4.1.4? It seems a very reasonable and decent guide, just don't want to go down this route if there's alternatives now available in 4.2.x.

Callum

Hi Callum,
can you share your version of the setup?
Also do you use OVS switch type in the cluster?
Regards,
Ales.

Unable to backend oVirt with Cinder
by Logan Kuhn
------=_Part_51316288_608143832.1472587678781
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 7bit
I've got Cinder configured and pointed at Ceph for it's back end storage. I can run ceph commands on the cinder machine and cinder is configured for noauth and I've also tried it with Keystone for auth. I can run various cinder commands and it'll return as expected.
When I configure it in oVirt it'll add the external provider fine, but when I go to create a disk it doesn't populate the volume type field, it's just empty. The corresponding command for cinder: cinder type-list and cinder type-show <name> returns fine and it is public.
Ovirt and Cinder are on the same host so it isn't a firewall issue.
Cinder config:

Hardering oVirt Engine
by Punaatua PK
Hello,
we are subject to PCI-DSS. I have some questions. We currently have setup oVirt in our environnement.
We created 2 Datacenter.
- one with a cluster with hosted engine on gluster (Hyperconverged env) which represents the "LAN" part
- one with a cluster with gluster storage wich is the DMZ
In PCI-DSS we have to secure communication (use HTTPs as much as possible). I did saw that ovirt-ha-agent (on hosted-engine capable host) check the status of the engine by sending GET request on the hosted-engine on port 80 (the same check that hosted-engine --vm-status did in fact).
Since ovirt 4.2.2, with the introduction of gluster eventing, a new flow (HTTP post resquest) is needed from gluster nodes to the engine. (In my case, it's a flow from the DMZ to the LAN part in HTTP (non secure)
Here is my question. Is it possible to "hardering" this part of the engine ?
Another question out of PCI scope. Events like warning and error in the dashboard are clean each days. I tried to find which process did that (look into /etc/cron.daily, root crontab, etc) on the engine
without succes. Is there any maintenance task that is run periodicaly ? Could we have the list of all the engine's task ? (regulary check the status of host, vm, storage) also the frequency ?
I would appreciate the help. (Great great product ovirt !) Thank you for your jobs ! We did manage KVM hypervisor as standalone machine without all the power that libvirt provides. No need to spend lot of money into licencing product (VSphere and co)

Non-responsive vm's due to crashed host and hosted vm liveliness check fails
by clam2718＠gmail.com
Dear Community:
The local drive on a host running ovirt-node-ng-4.1.9 in a three node cluster failed. I have production JIRA and Postres running on it at the time, not in HA, just simple vm's. Storage is via NFS on a Synology NAS. Hosted Engine was on a different host, but JIRA and Postgres vm's showed nonresponsive. I tried different things but then stupidly thought that upgrading my Hosted Engine would reinitialize the vm's that were on the failed host. Update of HE seemed to go well (output below) but now my Hosted Engine, while up, fails the liveliness check and the web management console is unavailable. I cannot console into the HE from the host it is running on. Below are the results of my attempts to console into the Hosted Engine. Please help! I have search forums, lists and Google but have not been able to fix this. My coworkers and manager are anxious.
---
When I try "hosted-engine --console" after setting the console password I get
The engine VM is running on this host
Connected to domain HostedEngine
Escape character is ^]
_
The prompt is non-responsive except for the escape character key combo.
---
"virsh -r list" gives ID 3, Name: HostedEngine, State: running
"virsh -r console HostedEngine" gives
Connected to domain HostedEngine
Escape character is ^]
error: operation forbidden: read only access prevents virDomainOpenConsole
"virsh -r vncdisplay HostedEngine" gives "0:0" and returns me to prompt
---
I am SSHed into the host running my Hosted Engine from a CentOS7 minimal install with packages xorg-x11-server-Xorg, xorg-x11-xauth and xorg-x11-apps installed. The result of "grep -i X11Forwarding /etc/ssh/sshd_config" shows it set to "Yes".
I SSH into the host using "ssh -Y root(a)xxx.xxx.xxx.xxx" I am logged into the CentOS7 minimal install as root. I know root is poor practice but was trying to minimize anything that could be causing an issue.
