Updating nodes
by Gabi C 14 May '14

14 May '14

Hello! Which is the proper way of keeping nodes up to date? I tried from WebUI, after putting node on mainetnance " Host is in maintenance mode, you can Activate it by pressing the Activate button. If you wish to upgrade or reinstall it click here ." but no effect, so I guess that installing ovirt repo and fedora-ovirt-preview repo is the proper way, right?

Hitachi hus110 and ovirt

Hi all I wonder if anyone has a working setup with a HDS device. Right now I am seeing a weird performance issue. With default multipath settings dd of zeros into the /dev/mapper lun shows at 0.2kbps while writing directly into a single path at /dev/sdb provides 900Mbps. I am using 10g iscsi with 4 ports on the HDS and dual port cnas on the hosts Thanks Dan

Ovirt-3.4.1: How to: Upgrading Hosted Engine Cluster
by Daniel Helgenberger 13 May '14

13 May '14

--=-wlqg4Mk7qpqjBQhvuW3U Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hello, failing to find a procedure how to actually upgrade a HA cluster, I did the following witch turned out to be working pretty well. I am somewhat new to oVirt and was amazed how well actually; I did not need to shutdown a single VM (well, one because of mem usage; many of my running VMs have fancy stuff like iscsi and FC luns via a Quantum Stornext HA Cluster): 1. Set cluster to global maintance 2. Login to ovit engine and to the upgrade according to the release nodes. 3. After the upgrade is finished and the engine running, set the first Node in local maintenance. 4. Login the first node and yum update (with the removal of ovirt-release as mentioned in release notes).* I rebooted the node because of the kernel update. 5. Return to oVirt and reinstall the Node from GUI, it will be set to operational automatically** 6. Repeat steps 3-6 for the rest of the Nodes. 7. Remove global maintenance. 8. Update the last Node.*** * I first tried to do this with re-install from GUI. This failed; so I used the yum - update method to update all relevant services ** I do not know if this was necessary. I did this because the hosted-engine --deploy does the same thing when adding a host. *** I found this to be necessary because I had all my Nodes in local maintenance and could not migrate the Hosted engine from the last node any more. The host activation in oVirt did not remove the local maintenance set prior to the update (witch it should, IMHO). It might be desirable to have a hosted-engine command option to remove local maintenance for that reason. --=20 Daniel Helgenberger=20 m box bewegtbild GmbH=20 P: +49/30/2408781-22 F:

getting 404 after fresh install of oVirt 3.4 on CentOS 6.5 (+ solution)
by Steven Van Acker 13 May '14

13 May '14

Hello all, I was asked to post the following problem on this mailinglist. After installing a clean CentOS 6.5 with a clean oVirt 3.4, following the instructions from http://www.ovirt.org/Download#Red_Hat_Enterprise_Linux_6.2FCentOS_Installat… I went to http://localhost.localdomain:80/ovirt-engine as indicated and was redirected to a 404 page. The same happened when using https. During the installation, engine-setup will print out the following on my VM with 512MB RAM: [WARNING] Warning: Not enough memory is available on the host. Minimum requirement is 4096MB, and 16384MB is recommended. SSH fingerprint: 4B:DE:48:26:99:AA:C0:72:E3:C8:B5:64:5F:6E:6D:00 Internal CA FB:82:FE:14:35:3A:BE:1A:B1:E6:99:C2:DC:CD:6D:E0:44:64:0F:47 Web access is enabled at: http://localhost.localdomain:80/ovirt-engine https://localhost.localdomain:443/ovirt-engine Please use the user "admin" and password specified in order to login into oVirt Engine The consequence of not having enough RAM for oVirt is that it will silently fail to start up, without apparent errors or warnings. In my view, the warning above should be rephrased as "Not enough memory is available on the host, oVirt will refuse to start" and colored red. The solution to this problem is to have at least 4GB of RAM, after which oVirt seems to start up fine (with only 1.2GB of RAM in use). kr, -- Steven

help with sriov vdsm hook?
by Darrell Budic 12 May '14

12 May '14

Anyone gotten the SRIOV hook to work with Solar Flare 10g cards? Any advice? I've gotten the hooks installed on my host nodes, and added a string to my engine. The card is up in SRIOV "mode" on the host and virtual instances are available. I can see the hooks running in the vdsm logs, but can't tell what they are doing from there. They are not attaching the sriov card instance to my VM though, so I'm at a loss. As an aside, it'd be really nice to have hooks register with the engine and add proper custom strings to the setup. Failing that, some explicit documentation on EXACTLY what string should be used for the hook would be nice. My first pass at it resulted in an improper string that caused my host to crash/hang and reboot when I attempted to start a VM with it the first time. Speaking of which, I added my custom string to UserDefinedVMProperties, not CustomDeviceProperties. Was that correct? Thanks, -Darrell
