In the docs, the proper order to update is: 1. update ovirt-setup packages on the engine yum update ovirt\*setup\* 2. update the engine engine-setup 3. update the OS on the engine yum update 4. reboot the engine if kernel/glibc/systemd got updated 5 upgrade hosts 1 by 1 Best Regards, Strahil NikolovOn Jun 13, 2019 16:27, sandeepkumar86k(a)gmail.com wrote: > > Thank you. > > I upgraded all three hosts one by one to oVirt-4.3 and then HE.

Re: Hosted Engine Abruptly Stopped Responding - Unexpected Shutdown
by Strahil 14 Jun '19

Hi Maria, I guess the memory usage is very specidic to the environment. My setup includes 2 VDOs, 8 gluster volumes , 2 clusters, 12 VMs and only 1 user - the built-in admin . In result my engine is using 4GB of RAM. How many users/storages/clusters/VMs do you have ? When you login on the engine, what is the process eating most of the RAM? My suspicion is the DB. If so, maybe someone else can advise if performing vacuum on DB during upgrade will be beneficial.

I try to find info about other ovirt virtualization set-ups and the amount of memory allocated so I can get an idea of what my set-up needs. The only thing that I found was that one admin had set ovirt up with 128GB and still needed more because of the growing needs of the system and its users and was about to upgrade its memory too. I'm just worried that ovirt is very memory consuming and no matter how much I will "feed" it, it will still ask for more.

oVirt engine/engine-setup with other port than default HTTPS 443 possible?
by Dirk Rydvan 13 Jun '19

13 Jun '19

Hello, in a home lab with only one puplic IPv4-Adress is the Port 443 a very precious one. The installation of oVirt 4.3 on a single node/host with bare metal installed CentOS works well. (oVirt Cockpit and local installed engine added after installation of Centos 7.6). But it is more difficult to change the port from 443 to maybe 4443 the save the port 443. The change in: - /etc/httpd/conf/conf.d/ssl.conf - /var/lib/ovirt-engine/jboss_runtime/config/ovirt-engine.xml and - disable selinux - add 4443 to public with firewall-cmd It does not work... now I see is more difficult than I think before... A port redirection at the edge route from <public-IPv4>:4443 to <private-IPv4>:443 does also not work, because the links points all to the standard https adress without a port number. Is there a way to change the default port 443 of oVirt engine to a other port? Many Thanks in advance!

The CPU type of the cluster is unknown. Its possible to change the cluster cpu or set a different one per VM.
by sandeepkumar86k＠gmail.com 13 Jun '19

13 Jun '19

Hi, I am having trouble in fixing the CPU type of my oVirt cluster. I have AMD EPYC 7551P 32-Core Processor hosts(x3) in a gluster cluster. The HE and cluster by default had the: AMD Opteron 23xx (Gen 3 Class Opteron). I tried changing it with this method(https://lists.ovirt.org/archives/list/users@ovirt.org/thread/XYY2WAG…, it didn't work as I can't move the Host to another cluster it complains (Error while executing action: *******: Cannot edit Host. Server having Gluster volume.) Then I tried updating the cpu_name manually in DB by following: https://www.mail-archive.com/users@ovirt.org/msg33177.html After the Update, the web UI shows it changed to AMD EPYC but if I click on Edit cluster it shows the "Intel Conroe Family" and again doesn't allow to modify. I am now stuck with unusable oVirt setup, my existing VMs won't start and throw: Error while executing action: ******: The CPU type of the cluster is unknown. Its possible to change the cluster cpu or set a different one per VM.) Please help or suggest to fix this issue.

Info about soft fencing mechanism
by Gianluca Cecchi 13 Jun '19

13 Jun '19

Hello, I would like to know in better detail how soft fencing works in 4.3. In particular, with "soft fencing" we "only" mean vdsmd restart attempt, correct? Who is responsible for issuing the command? Manager or host itself? Because in case of Manager, if the host has already lost connection, how could the manager be able to do it? Thanks in advance for clarifications and eventually documentation pointers Gianluca

If you run out of memory, you should take that serious.Droping the cache seems like a workaround and not a fix. Check if KSM is enabled - this will merge your VM's memory pages for an exchange for CPU cycles - still better than getting a VM killed.

I believe it was because the process qemu-kvm was killed after there was not enough memory for it but is this the real cause? I wasn't doing anything unusual before the shutdown to believe it was because of the new VM that was still in shutdown mode or anything of the sort.

Hi Alex, Did you migrate from gluster v3 to v5 ? If yes, then it could be the issue with v5.3 where permissions go wrong. If so, pick ovirt 4.3.4 as it uses a newer (fixed ) version of gluster -> v5.6 Best Regards, Strahil NikolovOn Jun 13, 2019 09:46, Alex McWhirter <alex(a)triadic.us> wrote: > > after upgrading from 4.2 to 4.3, after a vm live migrates it's disk > images are become owned by root:root.

High Performance VM: trouble using vNUMA and hugepages

Hi, I'm having trouble using vNUMA and hugepages at the same time: - hypervisor host hast 2 CPU and 768G RAM - hypervisor host is configured to allocate 512 1G hugepages - VM configuration * 2 virtual sockets, vCPUs are evenly pinned to 2 physical CPUs * 512G RAM * 2 vNUMA nodes that are pinned to the 2 host NUMA nodes * custom property "hugepages=1048576" - VM is the only VM on hypervisor host when I want to start the VM I'm getting the error message "The host foo did not satisfy internal filter NUMA because cannot accommodate memory of VM's pinned virtual NUMA nodes within host's physical NUMA nodes" VM start only works when VM memory is shrunk so that it fits in (host memory - allocated huge pages) I don't understand why this happens. Can someone explain to me how this is supposed to work? oVirt engine is 4.3.3 oVirt host is 4.3.4 thanks matthias
