documentation change suggestion / question
by Charles Kozler 08 Oct '16

08 Oct '16

Googling "ovirt windows agent" this is the first link that pops up: http://www.ovirt.org/documentation/internal/guest-agent/guest-agent-for-win… This doc seems non-intuitive and over complicated Specifically, the RedHat documentation that is 4 links below is simple as "install this package and mount the iso": https://community.redhat.com/blog/2015/05/how-to-install-and-use-ovirts-win… The former was updated as early as June of this year 1.) The RedHat document worked for me so I dont think oVirt 4.x cant use the same 2.) Why have separate areas of documentation that are so different from each other? This has caused me issues in the past whereby I found RH docs that were much more clear and concise 3.) Is there anyone who might want to merge RH docs with oVirt docs where the RH docs are better than oVirt? Thanks so much for providing such a great product! I just feel sometimes the docs are a little more developer-centric whereas the RedHat docs are more easily readable

VMs paused due to IO issues - Dell Equallogic controller failover
by Gary Lloyd 07 Oct '16

07 Oct '16

Hi We have Ovirt 3.65 with a Dell Equallogic SAN and we use Direct Luns for all our VMs. At the weekend during early hours an Equallogic controller failed over to its standby on one of our arrays and this caused about 20 of our VMs to be paused due to IO problems. I have also noticed that this happens during Equallogic firmware upgrades since we moved onto Ovirt 3.65. As recommended by Dell disk timeouts within the VMs are set to 60 seconds when they are hosted on an EqualLogic SAN. Is there any other timeout value that we can configure in vdsm.conf to stop VMs from getting paused when a controller fails over ? Also is there anything that we can tweak to automatically unpause the VMs once connectivity with the arrays is re-established ? At the moment we are running a customized version of storageServer.py, as Ovirt has yet to include iscsi multipath support for Direct Luns out of the box. Many Thanks *Gary Lloyd* ________________________________________________ I.T.

VM SSO
by Maxence Sartiaux 07 Oct '16

07 Oct '16

Hello, I try to use the VM SSO but no login, still on the logon screen ... I'm on ovirt 4.0.3, connected to an AD (Samba 4.5) + VMs Windows 7/10 stateless sysprep-ed to integrate to the domain and obviously the guest-agent is installed. My AD user can connect to the user panel, take a vm and connect to the console but no sign on on the windows. (the "Connect Automatically" option is ticked) Also, i don't know why but my username on ovirt panel has a double domain "u1@labo.lan@labo.lan" <- is this my problem ? The AD configuration is the configuration from the extension setup wizard, no custom config, no mapping Any ideas ? Thank you

VDSM Network Interface configuration
by Maton, Brett 07 Oct '16

07 Oct '16

Where is the configuration that VDSM uses to generate ifcfg files? My nameservers have moved and it seems to regenerate the ifcfg (ovirtmgmt) file overwriting the changes with the correct name servers in when the server is rebooted and s putting in the wrong (old) nameserver addresses. Where can I fix this ? Thanks
