Few questions for seasoned oVirt experts
by brad.riemann＠cloud5.com
Hello Everyone,
I'm new to oVirt so I was hoping I could pick the brains of those that may have been around the product longer than myself.
To start, I am leveraging oVirt 4.2, so all questions will be centered around them.
1. I am looking to utilize the ovirt engine for managing potentially thousands of datacenters, has anyone experienced large scale deployments or many-multi datacenter installations all managed under the same engine? FWIW: There will only be 1-2 servers per datacenter, with one cluster and 5-10 vNic assignments per cluster.
2. Has anyone dealt with the auto registration/approval process with oVirt engine? I'm finding various documentation from different generations of oVirt, but haven't felt comfortable with what i've found since my instance doesn't seem to have features that i'm reading about.
My goal is to ship servers to a site with a basic image and when it boots up it reaches out to our ovirt engine, in turn I can automate a validation of pending approval requests based on host criteria, i'm just struggling to figure out if the automatic registration is even a thing in the latest version.
thank you in advance, I appreciate any feedback on the matter.
-Brad

VLAN Trunk interface with OVN provider (ovirt HE 4.2.6.4-1.el7)
by Davide Butti
Hello; I'm having some hard time getting my oVirt cluster back to work, after the last update to 4.2.6.
One thing that does not work anymore is VLAN Trunks; before the update, the cluster was running in OVS mode, and I could define logical networks without VLAN tag; then, networks packets got forwarded to the guest as "tagged".
Right now version 4.2.6 won't allow me to assign the (OVS) Logical network to the guest NICs anymore, but it insists that I use a vNIC profile from an external provider.
First question: Is this expected? Must I really work with externally provided networks only?
Anyway, for the vNIC interfaces that only carry untagged traffic, I was able to define an external OVN network, connect it to the corresponding "Data center Network", and everything works as it did before. But the "trick" does not work for "trunk" interfaces that should carry VLAN tagged traffic.
So to the second (main) question? How is this to be solved? Is there a way to define a VLAN trunk under OVN? Or is there a way to pickup a Data Center logical network to attach to the vNIC as we did before?
Thanks in advance for your help!

Cannot configure local storage, network issue?
by Callum Smith
Dear All,
I'lm getting this problem when trying to add local storage from the node:
Cannot edit Host. Moving a host to a cluster with different management network is not allowed. That might cause connectivity loss.
The cluster the host is in uses a different default network to the default cluster - is this the problem?
Regards,
Callum

Hosted Engine - Unable to connect after deployment.
by Jeremy Tourville
I have a new installation of ovirt hyperconverged single node using glusterfs. I was able to run gdeploy and then use the web interface to run the self hosted engine setup. Ovirt node is running 4.2.5.1. If I go to localhost>ovirt machines tab from my node I see a message in the upper right corner saying "ovirt login in progress" with spinning icon after putting in the credentials. After a minute or less I am redirected to -
https://engine.cyber-range.lan/ovirt-engine/web-ui/authorizedRedirect.jsp...
where the web page says- "the connection has timed out."
"The server at engine.cyber-range.lan is taking too long to respond." I also notice I no longer have the option to choose VNC or console because the web page keeps on attempting to reconnect. When I tried to connect using a console with virt-viewer it errored out on me. (I didn't make note of the message)
Virtualization>hosted engine tab reports that my hosted engine is up. This is further confirmed by CLI #hosted-engine --check-liveliness. On occasion though, CLI reports HE is not up. If I try to ssh to HE sometimes I can connect, but it is VERY slow to do so. Once I connect it often appears to freeze or be very slow to enter any input commands to the HE. HE is effectively useless.
I get frequent log messages in the console- "ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine ERROR Engine VM has bad health status, timeout in 300 seconds"
This is a new setup, so I haven't lost anything if I need to start over. What do you suggest? Is there an easy way to recover or should I reinstall HE? Thanks for your advice!
