Upgrading
by Fernando Fuentes 13 Oct '15

13 Oct '15

Is there a best practice when upgrading from ovirt 3.4 to 3.5? I upgraded my development server which is a self hosted server and I just did a regular update without putting anything under maintenance... Though my vm's where turned off. It all went well and the migration from krb/ldap to AAA went smoothly and so far is running like a champ. I am about to do the same to our production cluster and was wondering if I must put all Hosts under maintenance before I do the upgrade? Is it any different than a self hosted ovirt setup? Thanks in advance for all/any tips from the mailing list!

VM Network activity on ovirt UI
by Marc Seward 13 Oct '15

13 Oct '15

I'm generating network activity on a VM using iperf.The VM acts as an iperf client.On the client,iperf reports that data has been successfully sent to iperf server.The iperf server also shows that it's successfully receiving data from the iperf client.But,network is at 0% on the ovirt UI.The client and server are on different private networks. On the same VM,when I generate network activity by fetching a file from a public network using wget,the network column correctly shows activity on the ovirt UI for the VM. Could someone help me understand why I am unable to see network activity on the ovirt UI when iperf is used? Appreciate your help.TIA.

Any way to correlate a VM disk (e.g. /dev/vda) to the vdsm ovirt disk?
by ccox＠endlessnow.com 13 Oct '15

I want to correlate virtual disks back to their originating storage under ovirt. Is there any way to do this? e.g. (made up example) /dev/vda maps to ovirt disk disk1_vm serial 978e00a3-b4c9-4962-bc4f-ffc9267acdd8

live snapshot merge missing after vdsm update

--_000_DBXPR06MB544F4ED5888DED7D2252803C3300DBXPR06MB544eurprd_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi all, 1 of our older clusters in use, consists of 2 nodes contain Fedora 20, with= the virt-preview repository enabled. The Engine itself is installed on a dedicated server (CentOS 6) and is stil= l on version 3.5.1.1-1.el6. During some maintenance a couple of days ago on the Fedora 20 nodes, also = the installed vdsm package was updated by the engineer working on the nodes= . We went from version 'vdsm-4.16.10-8.gitc937927.fc20' to 'vdsm-4.16.26-0.fc= 20'. This morning I wanted to remove some old snapshots on running vm's, only to= find out that the delete button is once again greyed out. I also created a new snapshot on a running vm to test if it would only happ= en on snapshots that were already there before the update, but the delete b= utton would still remain greyed out. Only turning off the vm allows me to use the delete button. When looking at the nodes within the cluster, they both still have Live Sna= pshot Support on Active. Before the vdsm update, the live merge functionality worked perfectly. Anybody experienced something similar? Could It be because the Engine is still running on 3.5.1? We are also running 2 clusters with F21 nodes that have the same vdsm versi= on nummer installed and they don't have an issue at all; connected to the s= ame engine.

oVirt Engine redundant ?

13 Oct '15

--=_b5ae4dd5edb7f3efcaaf1d71e197ef06 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII Hello I got a question regarding the redundancy of oVirt Engine; where we can control everything through the GUI; aka the vCenter. Initially; my setup was on a single server; installed following the doc AllinOne. Then after; i figured out that i would need redundancy; so i installed a second node. my question is about the vCenter; is it possible to start it on the second node when the first node is down or in maintenance ? how to ensure it is replicated ? i see there is a postgres DB on first node; but not on second node. I'm a bit worried. So, is it possible to have a dormant/slave ovirt ENGINE (oVirt web GUI ) ; and if yes, could you point me to the related documentation as i didn't find it. Maybe, it is possible to run it in a VM ? is it a good idea ? and is it still possible to migrate ?

Best practice
by Fernando Fuentes 12 Oct '15

Is there a best practice when upgrading from ovirt 3.4 to 3.5? I upgraded my development server which is a self hosted server and I just did a regular update without putting anything under maintenance... Though my vm's where turned off. The migration from krb/ldap to AAA went smoothly and so far is running like a champ. I am about to do the same to our production cluster and was wondering if I must put all Hosts under maintenance before I do the upgrade? Thanks in advance for all/any tips from the mailing list!
