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

Upgrading ovirt 4.1 -> ovirt 4.2
by Alex K
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?

ovirt and gluster network config
by william.dossett＠gmail.com
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

Unable to start VM on host with OVS networking
by Jonathan Dieter
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.

oVirt web console for VM
by Hari Prasanth Loganathan
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...
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
