After minor upgrade oVirt Node to 4.2.3 can't start Virtual machine
by stefan.palecek＠x112.cz 10 Jun '18

10 Jun '18

Dear all, after upgrade oVirt Node to latest 4.2.3 I can't start any virtual machine with network interface. VM machine without network interface starts normally. Exactly the same situation is on freshly installed oVirt node machine with different hardware. I use openvswitch on both machines. After some searching I found out that there are the same version of openvswitch(2.9.0-3) on old and new version of oVirt node but different versions of libvirt(3.9.0-14 vs 3.2.0-14) Error message of libvirtd when the VM machine fail to start: VM OPNsense is down with error. Exit message: Unable to add bridge ovirtmgmt port vnet0: Operation not supported. Any suggestions? Thank you. Stefan

Upgrading ovirt 4.1 -> ovirt 4.2
by Alex K 10 Jun '18

10 Jun '18

Hi all, If one cannot perform a minor upgrade of ovirt 4.1 (due to surprisingly missing repos...) is it ok to ignore this and proceed directly to major upgrade to ovirt 4.2? I don't like very much the idea as I don't know to what surprises I will have considering that this is production. What is your experience/suggestions? Alex

ovirt and gluster network config
by william.dossett＠gmail.com 10 Jun '18

10 Jun '18

Hi, I have my 5 ovirt nodes up and running and starting to move forward with actual ovirt and gluster setup. I am using gdeploy for deployment. the play book fails saying /dev/sdb is blacklisted by filter? I am following the blog up and running on the ovirt site. It mentioned adding # disable multipath [script2] action=execute file=/usr/share/ansible/gdeploy/scripts/disable-multipath.sh to get it to work, but it does not work. The script 3 section after this does have the file=/usr/share/gdeploy/scripts/blacklist_all_disks.sh in it. What can I do to get past this? Also not sure if I should be modifying the script/play as I don't really want an arbitrator host - if I have 5 real hosts all with the same storage in them? (10TB in each) and it only account for 3 hosts, can I add the other two later or should I try to modify the playbook to include these initially? I am sure I will be setting this up several times before I get it right, but at the moment I can't get past this error. Any help would really be appreciated! Thanks

ansible role for setting up ovirt-engine development environment
by Greg Sheremeta 09 Jun '18

09 Jun '18

Hi all, I created an ansible role for setting up ovirt-engine development environment. If you are not familiar with ansible, it's a tool for getting a machine into a specific 'state'. A role is a 'type' of machine, like 'db server' or 'web server' or 'dev rig.' Roles are 'applied' to machines. So you can apply the ovirt-engine-devel role to setup a working development environment instantly. It works over ssh or locally. You can see it in action here: https://imgur.com/a/FwEkmy5? Known issues: - not tested on fc28 yet - not tested on EL yet - name -- in EL/Fedora -devel package names are a convention for something - idempotency needs fixing when code edited Improvements - gerrit setup - changing database name (multiple engine environments, etc.) code: https://github.com/gregsheremeta/ovirt-engine-devel-example https://github.com/gregsheremeta/ovirt-engine-devel Feedback welcome, and if you find it interesting, I'd love assistance :) Best wishes, Greg -- GREG SHEREMETA SENIOR SOFTWARE ENGINEER - TEAM LEAD - RHV UX Red Hat NA <https://www.redhat.com/> gshereme(a)redhat.com IRC: gshereme <https://red.ht/sig>

Unable to start VM on host with OVS networking
by Jonathan Dieter 08 Jun '18

08 Jun '18

I have a production ovirt setup that's gone through multiple updates over the years. At some point when 4.0 or 4.1 came out, I switched from legacy networking to OVS, and everything worked perfectly until I upgraded to 4.2. Since I upgraded to 4.2, I've been getting messages that the networks were all out of sync, but everything continued working properly. Today I tracked down the network sync problem, fixed it on one of my three hosts, and then attempted to start a VM on the host. It refused to start with the error message: "Unable to add bridge ovirtmgmt port vnet0: Operation not supported". From what I can tell, the xml being generated is still for the old legacy network. I completely reinstalled the node, using the latest 4.2.3 node ISO image, and it still doesn't work. In the cluster, the switch type is "OVS (Experimental)" (and this option can't be changed, apparently), the compatibility version is 4.2, the firewall type is firewalld and there's no "Default Network Provider". I suspect that my upgrades have somehow left my system in half OVS/half legacy mode, but I'm not sure how to move it all the way to OVS mode and I don't want to mess with the other two hosts until I'm sure I've got it figured out. My (compressed) vdsm.log is at https://www.lesbg.com/jdieter/vdsm.log.xz and my (compressed) supervdsm.log is at https://www.lesbg.com/jdieter/supervdsm.log.xz. If anyone could point me in the right direction to get this fixed, I'd sure appreciate it. Jonathan

oVirt web console for VM
by Hari Prasanth Loganathan 08 Jun '18

08 Jun '18

Hi Team, I am able to 1) Create a VM 2) Create and Attach DISK and NIC 3) I powered on the VM but I am yet to provide the network configuration for it. So there is no IP assigned, It is in Green color with UP arrow. Now I need to connect to this virtual machine and login using Guest console, I saw a documentation : https://www.ovirt.org/documentation/how-to/guest-console/connect-to-guest-d… But it is not clear. *Use Case needed : * 1) oVirt is running in centOS say running in 172.1.1.1 2) I have a Ubuntu machine say 192.2.2.2, I used the Firefox browser to login to oVirt engine (172.1.1.1) 3) Since my VM is powered ON, I need to use the console to login from my browser. Please let me know the steps. If you need anymore information, please let me know. Thanks, Hari
