Ovirt 4.0 Login Issue
by Melissa Mesler 17 Aug '16

17 Aug '16

I am running 4.0 on CentOS 7.2. Sometimes when I first log in to the admin page, it will give me and error that says "Request state does not match session state." Then if I go through the process of logging in again, it will go through with no issue. It doesn't do this every time but it does do it quite often. Any ideas on why? - MeLLy

JsonRpc (StompReactor)::ERROR::2016-08-17 12:32:05,348::betterAsyncore::113::vds.dispatcher::(recv) SSL error during reading data: unexpected eof Another thing i observed is , f the UI is idle for some time it gets logged out automatically.

Upgrade hosts/nodes from engine
by Hanson 17 Aug '16

17 Aug '16

Hi Guys, Quick question, I have my nodes on a bond-bridge-privateVlan setup, and my engine on a bond-bridge-publicVlan setup for remote monitoring. Understandably, the nodes are complaining that they are failing updates. (They're on a private vlan, and only configured with IP's in that vlan, the public vlan doesn't have IP's set on the hosts so they can pass it to VMs). Is there a way to have the engine do the updates on the node using its internet connection, like a proxy? For security reasons I like to have the nodes not publicly accessible, as we see hundreds if not thousands of ssh attempts, and root would probably be the most attacked account. Thanks, Hanson

Team, I got two oVirt Servers. One in 4.0.2 and one in 3.6.X I love the new 4.0 dashboard, But I need a way to continue to build reports with ease, 3.6 Can do this with ovirt-reports. How can I make my oVirt 4.0.2 send data for reports to my ovirt reports on 3.6? Thanks for the help team! Regards, -- Fernando Fuentes ffuentes(a)txweather.org http://www.txweather.org

Gluster replication on 1Gb interfaces
by Fernando Frediani 16 Aug '16

16 Aug '16

Hi all. I understand using 10Gb interfaces when using Gluster is advised for helping with data replication specially in situations where a node went down for a while and need to re-sync data. However can anyone tell if using one 1Gb interface dedicated for it in hosts with 1.8 TB of Raw storage would be still Ok or can it cause severe impact on performance ? What are the chances of a 1Gb nice being saturated during normal operation ? Thanks Fernando

edit gluster storage domain
by Edward Clay 16 Aug '16

16 Aug '16

Hello, I need to edit a glusterfs storage domain to add the mount option " backupvolfile-server=SERVER" So when the primary servers IP is not accessible the remaining servers will be used to retrieve data stored on the gluster volume. Right now when I try to edit the storage domain the mount options box is grayed out and not editable. I recently had to take all vms down so I put the HV in maintenance mode and the edit options wasn't present. I need to understand if this is the correct option to make a glusterfs volume fault tolerant? Also I need to understand how to make this edit in the ovirt web interface or other method. TIA

oVirt 4 with custom SSL-certificate and SPICE HTML5 browser client -> WebSocket error: Can't connect to websocket on URL: wss://ovirt.engine.fqdn:6100/

Hello oVirt guru`s ! I have successfully replaced the oVirt 4 site SSL-certificate according to the instructions from "Replacing oVirt SSL Certificate" section in "oVirt Administration Guide" http://www.ovirt.org/documentation/admin-guide/administration-guide/ 3 files have been replaced: /etc/pki/ovirt-engine/certs/apache.cer /etc/pki/ovirt-engine/keys/apache.key.nopass /etc/pki/ovirt-engine/apache-ca.pem Now the oVirt site using my certificate and everything works fine, but when I try to use SPICE HTML5 browser client in Firefox or Chrome I see a gray screen and message under the button "Toggle messages output": WebSocket error: Can't connect to websocket on URL: wss://ovirt.engine.fqdn:6100/eyJ...0=[object Event] Before replacing certificates SPICE HTML5 browser client works. Native SPICE client works fine. Tell me what to do with SPICE HTML5 browser client?
