affinity/pool/fencing ?
by Nardus Geldenhuys
Hi oVirt land
Hope you are well. Don't even know what to call this. But let me describe
what I want to achieve.
We have a cluster with say 100 vm's. But we want two use two hosts in the
cluster two run only certain VM's. I think you can do that with affinity
rules. But how can I restrict those two hosts to only run the VM's, meaning
that no other VM's will run on them.
I don't want to go and edit the 100 other VM's to not run on 2 hosts. Is
there an easy way for doing this?
Oracle VM uses pools, I dont know what vmware uses.
Any advice will help.

Management Engine IP change
by Anton Louw
Hi All,
Does somebody perhaps know the process of changing the Hosted Engine IP address? I see that it is possible, I am just not sure if it is a straight forward process using 'nmtui' or editing the network config file. I have also ensured that everything was configured using the FQDN.
Thanks

Re: Failed to execute stage 'Environment customization': IPAddress() does not support netmasks or subnet prefixes! See documentation for details.
by James Loker-Steele
Hi Anton,
I tried without the /24 it threw an error saying it wasn’t a correct cidr address 10.93.130.50/64 (it added the /64)
Interesting though, I have manually created the ovirtmgmt bridge interface and assigned an IP address to it (as per another post) and it has gone past this step now without the /24.
The part I am crashing out on is being unable to resolve the address. I can post the error shortly.
This is strange behaviour as the host can resolve, but I will be adding dns addresses to the ovirtmgmt interface and trying again(post didn’t show to add them)
When I installed <4.2 I didn’t get these issues it went smoothly.
The problems seem related to ansible.
Best regards
James

Hi All,
Trying to install a self-hosted engine but cannot get past this step.

Adding hypervisor fails, yum links deprecated (Centos 7.7/ oVirt 4.3)
by wjb2130＠cumc.columbia.edu
Greetings. In a multi-hypervisor environment, we are running Centos 7.7.1908, with ovirt-4.3. There are problems adding a new hypervisor, because all the yum resources have switched in favor of newer versions.
Is there a proceedure to add a hypervisor under the oVirt Virtualization manager while retaining an older, known working OS version like Centos 7.7.1908 ? Upgrading everything across the board isn't an immediate option. There are many VMs and hypervisors in production, and can't be disturbed.
In sum: is it still possible to install known working 4.30.33-1.el7? All that is presented now is 4.30.46-1.el7
I ran: yum install vdsm-4.30.33-1.el7.x86_64. This completed. However, when I tried to add the resulting hypservisor using the oVirt web UI, that fails. Logs on that management server showed that the install process insists on using 4.30.46-1.el7. Any way to avoid this?
2020-07-22 20:30:58,621-04 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (VdsDeploy) [45782a5f] EVENT_ID: VDS_INSTALL_IN_PROGRESS_ERROR(511), An error has occurred during installation of Host hypervisor7: Failed to execute stage 'Package installation': [u'vdsm-4.30.46-1.el7.x86_64 requires lvm2 >= 7:2.02.186-7.el7_8.1'].

change lun for hosted_engine use?
by Philip Brown
I currently have a self-hosted engine, running in a dedicated ISCSI storage domain.
I'd like to change the backend hardware for the storage.
i think there's some longwinded and complicated method of shutting down the engine, backup, creating a NEW one, restore, and whoknowswhat.
I was wondering though, if maybe there's a way to just add an iscsi lun to the storage domain, and tell ovirt, "Hey, move the stuff over to that other lun"
?
Ive added the new lun already :) havent found a reference to move the files' residence though.
If it helps, my end goal is to remove that lun completely.

Deploying new Ovirt Node on new 4.4 cluster. ansible code incorrect
by erin.sims＠bookit.com
Hi Guys we attempted to deploy a new ovirt cluster two weeks ago. 4.4.1 and 4.4.0 Once we got the engine up we tried to add a new node and Ansible began to fail on the deploy scripts. I search the logs and discovered the Ansible script was not evaluating the right versions of python, python3. Also the yum module should of been dnf. Once i change those in many places it worked great. I am just trying to figure out what went wrong with our deploy so this doesn't happen again. we are using a hosted engine on a centos 8 vm. please let me know what logs i can grab or apps to run for more details.

Centos based Ovirt 4.3.10.4-1.el7, VMs cannot communicate over VM networks
by Konstantinos B
Hi all
Can anyone point into the right direction on how to troubleshoot VM connectivity between VM networks?
The nodes have been double-installed from the engine.
The external ovn-provider is reachable through HTTP.
ovs-vsctl shows the interfaces once a VM is booted.
However, no traffic is passed between VMs.
Any help is greatly appreciated.
