Ovirt Hyperconverged Cluster
by raffaele＠stefanile.com
I am installing ovirt 4.2 on three nodes. I am using centos with ovirt cockpit. My /sdb is my boot disk and /sda is my local storage,
When I started the setup with cockpit I selected the sda but the ansible script stay on sdb. I have fix all changing the playbook manually but in the execution the gdeploy tool stay blocked on TASK [Create Physical Volume] .
I don't find any logs. How I can fix that?

Hello,
any successful stories of the Nvidia T4 usage with the Ovirt?
I was wondered if one would get 2 hosts each with T4s , are there live
migrations possible?

Spice console very poor performance for Windows 10 vm
by Leo David
Hello Everyone,
Maybe I am something wrong, but spice console seem to be very laggy and
slow for windows 10 vms. I have tried both qxl and qxl-dod drivers, but no
luck so far...
As a notice, the Win 2012R2 vm console is running fine, the problem seems
to only affect Windows 10.
Any ideas, what should I do to sort this out ?
Thank you very much !
Leo

Using a synology as an nfs storage
by Andy Michielsen
Hello,
I'm setting up a 3 node cluster with the ovirtnode iso and a seperate
server with the engine on and a synology for nfs storage.
I have done my configuration and I'm able to mount the share manually on
the node with a command. Also on the server with the engine on I can mount
it manually. But when I want to do it through the webinterface to add a
data domain it say the permissions are wrong.
Any idea's on how to figure this out ?
Kind regards.

Re: USB Passtrough device problem
by Strahil
You can attach the usb to an oVirt node and check the module in use there.
Then you can try patthrough the device and check the module in use on the VM (if it's linux) or install the driver (if Windows).

Ovirt Hyperconverged Cluster
by raffaele＠stefanile.com
Hi all,
I have configured a 3 nodes cluster with an Hyperconverged gluster.
I have used 2 network interface bonded with one VLAN for the mgmt and an other one for the storage.
When I use cockpit to deploy the hosted engine I receive this error.
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The host has been set in non_operational status, please check engine logs, fix accordingly and re-deploy.\n"}
The ovirt version is 4.3
Someone have a similar problem?

Proper way to upgrade hosts OS?
by Nicolas Ecarnot
Hello,
We're not using nodes but CentOS 7.x hosts.
Do you know if some documentation has been written about the proper way
to upgrade the operating system of the hosts, and especially how to
prevent breaking dependencies or cause versions flaws?
Thank you.
