Unable to deploy to new host
by David White 19 Sep '22

19 Sep '22

I currently have a self-hosted engine that was restored from a backup of an engine that was originally in a hyperconverged state. (See https://lists.ovirt.org/archives/list/users@ovirt.org/message/APQ3XBUM34TG7…) This was also an upgrade from ovirt 4.4 to ovirt 4.5. There were 4 hosts in this cluster. Unfortunately, 2 of them are completely in an "Unassigned" state right now, and I don't know why. The VMs on those hosts are working fine, but I have no way to move the VMs or manage them. More to the point of this email: I'm trying to re-deploy onto a 3rd host. I did a fresh install of Rocky Linux 8, and followed the instructions at https://ovirt.org/download/ and at https://ovirt.org/download/install_on_rhel.html, including the part there that is specific to Rocky. After installing the centos-release-ovirt45 package, I then logged into the oVirt engine web UI, and went to Compute -> Hosts -> New, and have tried (and failed) many times to install / deploy to this new host. The last error in the host deploy log is the following: 2022-09-18 21:29:39 EDT - { "uuid" : "94b93e6a-5410-4d26-b058-d7d1db0a151e", "counter" : 404, "stdout" : "fatal: [cha2-storage.mgt.example.com] FAILED! => {\"msg\": \"The conditional check 'cluster_switch == \\\"ovs\\\" or (ovn_central is defined and ovn_central | ipaddr)' failed.

oVirt 4.5 on Rocky 9
by Bjorn M 19 Sep '22

19 Sep '22

Hi, I'm moving all my infra nodes to Rocky 9 and my oVirt cluster is next on the list. I'm deploying a standalone oVirt VM on a KVM box and will set up the hosts afterwards. All are to run on Rocky 9 x86_64. I followed https://www.ovirt.org/download/install_on_rhel.html and created an Ansible playbook to set up the customisations. I now have all repos set up correctly, or at least that is my understanding. When I run yum search ovirt-engine I get a number of packages available from the repos, but not the ovirt-engine package. I do see the ovirt-hosted-engine, but I prefer the standalone option. This makes sense as I don't find the package at http://mirror.stream.centos.org/SIGs/9-stream/virt/x86_64/ovirt-45/Packages… , which I where all ovirt- packages are, except this one. Yum whatprovides engine-setup also turns out negative. I then decided to install ovirt-engine-appliance 4.5-20220419160254.1.el9 from ovirt-45-upstream, but that package produces an error on the GPG key import. It's unclear whether the issue is on my specific stack or wider. The missing ovirt-engine package is confusing though. Any help is appreciated, Cheers, Bjorn OUTPUT : (0)[root@ovirt ~]# yum repolist Updating Subscription Management repositories.

Re: Error during deployment of ovirt-engine
by Peter H 19 Sep '22

19 Sep '22

Hi Jonas, I get the same error when I try to install. Last weekend I managed to do it (but with a lot of other problems) so something has changed during the week. After the VM is up I logged in through ssh and saw that the oVirt appliance comes with Python-3.6 and Python-3.8 which both have netaddr installed. Part of the log: ... [ INFO ] TASK [ovirt.ovirt.engine_setup : Update setup packages] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.engine_setup : Copy yum configuration file] [ INFO ] changed: [localhost -> 192.168.222.35] [ INFO ] TASK [ovirt.ovirt.engine_setup : Set 'best' to false] [ INFO ] changed: [localhost -> 192.168.222.35] [ INFO ] TASK [ovirt.ovirt.engine_setup : Update all packages] [ INFO ] changed: [localhost -> 192.168.222.35] [ INFO ] TASK [ovirt.ovirt.engine_setup : Remove temporary yum configuration file] [ INFO ] changed: [localhost -> 192.168.222.35] [ INFO ] TASK [ovirt.ovirt.engine_setup : Set offline parameter if variable is set] ... I noticed that after the task "Update all packages" Python-3.9 gets installed and that version does not have netaddr installed. My theory is that the playbook somehow uses the newest version of Python which is installed. pip3.9 list Package Version ------------ ------- ansible-core 2.13.3 cffi 1.14.3 cryptography 3.3.1 idna 2.10 pip 20.2.4 ply 3.11 pycparser 2.20 PyYAML 5.4.1 setuptools 50.3.2 six 1.15.0 I have tried another run where I installed the netaddr module as soon as Python-3.9 got installed and that installation went further but then it had another error. When I log into my hosted engine VM from last week there is no Python-3.9. My dnf(1) skills are not good enough to figure out which dependency is causing Python-3.9 to be installed. There are probably a lot of other modules missing that can explain the other error(s) I see. I will see if I can find out how to file a proper bug report. BR Peter

Re: Should I migrate existing oVirt Engine, or deploy new?
by David White 19 Sep '22

19 Sep '22

Hi Paul, Thanks for the response. I think you're suggesting that I take a hybrid approach, and do a restore of the current Engine onto the new VM. I hadn't thought about this option. Essentially what I was considering was either: - Export to OVA or something OR - Build a completely new oVirt engine with a completely new domain, etc... and try to live migrate the VMs from the old engine to the new engine. Do I understand you correctly that you're suggesting I install the OS onto a new VM, and try to do a restore of the oVirt settings onto the new VM (after I put the cluster into Global maintenance mode and shutdown the old oVirt)?

Migrating VM from old ovirt to a new one
by Facundo Badaracco 18 Sep '22

18 Sep '22

Hi everyone I would like to ask you a question I have an ovirt 4.4 which got corrupted certs and I can't access the gui. It gives me error 500 internal when I want to access. I have a new ovirt 4.5 on glusterfs which I would like to migrate all my vm's to. Is this possible? Can it be done by cli? It would save me from having to reinstall all the vm's.

Gluster setup for oVirt
by Jonas 18 Sep '22

18 Sep '22

Hello all I tried to setup Gluster volumes in cockpit using the wizard. Based on Red Hat's recommendations I wanted to put the Volume for the oVirt Engine on a thick provisioned logical volume [1] and therefore removed the line thinpoolname and corresponding configuration from the yml file (see below). Unfortunately, this approach was not successful. My solution is now to only create a data volume and manually create a thick provisioned gluster volume manually. What would you recommend doing?

static IP with OVN subnet
by ravi k 16 Sep '22

16 Sep '22

Hello, Hope you are all doing well. We have an interesting thing going on and so wanted to share with you all for some ideas and feedback. We configured a cluster with OVS switch and added an external network with subnet. So OVN started managing the subnet using DHCP. But here's the problem. When we add a nic with this network, an ip is assigned by DHCP. But we want an IP of our choice to be assigned. Here's what we tried. 1. We tried using the ovn-nbctl lsp-set-address like ovn-nbctl lsp-set-addresses 7840c97b-73c2-4246-a2a8-0e9e5b7f420a "56:6f:6b:54:00:ec 10.19.3.8" to update the static IP. But this does not persist a NIC unplug or a VM reboot. So you might ask why not just try assigning a static IP and not add the external subnet. We want to use security groups. For security groups to work, the ip assigned to the NIC and the IP in the value for fixed_ips in `openstack port show` should be the same. So the same thing repeats here as well. If we use the `openstack port set` to update the fixed_ips, a NIC unplug or a VM reboot will remove the IP. We have an internal IPAM that provides us IPs during our automated provisioning. Did anyone try this or have any ideas how to work around this? The only option seems to be just use DHCP and then update that IP in our internal IPAM tool. Please let me know if I'm unclear and any more info is required. Regards, rav
