Shutting be down kvm host does what to VMs
by Louis Bohm 18 Jun '20

18 Jun '20

I have a single ovirt host running 2 VMs. If I do a shutdown -h now on the kvm host will ovirt do a similar shutdown command on the VMs? And wait for them to shutdown before finishing it's shutdown? Please do not tell me I should have 2 physical hosts. I know but it's not in the clients budget. Thanks, Louis

cant edit ISO domain in any way
by Philip Brown 18 Jun '20

18 Jun '20

oVirt 4.3: Okay, I found documentation that I cant have more than one "ISO" type storage domain. I can kinda understand that. But, I cant even edit or delete the existing one? Even when logged in to the oVirt GUI as admin@internal? Is this some kind of bug or something?

Information requested on oVirt + RDO/OpenStack
by Glenn Marcy 18 Jun '20

18 Jun '20

I am hoping to try out adding RDO to oVirt after things with CentOS 8.2 settle down. I've done deployments of RDO on KVM before without any issues (TripleO Quickstart), but this would be my first time trying it on oVirt. Since oVirt recently updated to the openstack-java 3.2.9 packages, is there a specific version of OpenStack (Train or Ussuri) that runs on CentOS 8.x that I need? Are there any issues with the fact that oVirt already uses and/or provides some OpenStack services? Does the fact that OpenStack deployments are now more "containerized" present any issues I should be aware of? Are there initiatives for further convergence between oVirt, RDO/OpenStack and OKD/OCP that are changing this space where it would make sense to follow and/or participate in those efforts? I'm starting out with oVirt to get an understanding of the capabilities that it brings to the table, but interested in the convergence of the other technologies that would benefit from having oVirt as, or a part of, the foundation. Best Regards, Glenn

Ansible ovirt_disk module: how to attach disk without activation
by Gianluca Cecchi 17 Jun '20

17 Jun '20

Hello, root problem in a 4.3.8 environment is that sometimes when I hot add a floating disk to a VM in web admin gui, it attaches and also activates it by default (the flag is checked by default, but you can uncheck it) and this two-phases action fails as a single step. What I get is: VDSM ovhost command HotPlugDiskVDS failed: Requested operation is not valid: Domain already contains a disk with that address And then the VM event regarding hot add disk failure. I'm going to investigate more: it should be a past bug already solved in theory by my libvirt sw version (I've to crosscheck its id)... but I still get the error sometimes. What programmatically works is to attach the disk without activating it (this step always completes with success) and then activate the disk as a separate operation (this one typically fails the first time when I have the "problematic" situation, but then the second time succeeds). So I would like to use it as a workaround in the mean time. The problem reflects using the ansible module ovirt_disk, that by default activates the disk. So I have tried to specify "activate: no" (introduced in 2.8, readings the docs) when I attach it, but it seems not to work as expected. I'm testing using awx and its info says: AWX 9.0.1.0 Ansible 2.8.5 I tried this on a VM that (as usual when you want to reproduce... ;-) doesn't show the problem: ovirt_disk: auth: "{{ ovirt_auth }}" state: attached activate: no name: "{{ tobe_sw_disk_name }}" vm_name: "{{ ansible_hostname }}" size: "{{ current_sw_disk_size }}" interface: virtio_scsi delegate_to: localhost register: disk_attach_info But going to see registered variable it contains "active: true": "disk_activate_info": { "changed": false, "id": "6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827", "diskattachment": { "href": "/ovirt-engine/api/vms/b5c67c93-bd5d-42b6-a873-05f69cece2f1/diskattachments/6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827", "id": "6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827", "active": true, "bootable": false, "disk": { .... In fact I followed with the step to activate the disk: ovirt_disk: auth: "{{ ovirt_auth }}" state: present activate: yes name: "{{ tobe_sw_disk_name }}" vm_name: "{{ ansible_hostname }}" size: "{{ current_sw_disk_size }}" interface: virtio_scsi delegate_to: localhost register: disk_activate_info But in playbook run I got: ok: [target_vm -> localhost] And inside registered variable "changed: false": "disk_activate_info": { "changed": false, "id": "6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827", "diskattachment": { "href": "/ovirt-engine/api/vms/b5c67c93-bd5d-42b6-a873-05f69cece2f1/diskattachments/6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827", "id": "6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827", "active": true, ... Any tip to realize what needed: task to only attach disk without activating it and then task to activate the disk? Thanks in advance, Gianluca

help: renamed master volume
by Philip Brown 16 Jun '20

16 Jun '20

Im pretty new to ovirt. Trying to upgrade an old install from 4.1 to 4.3 on the way, I browsed into the Storage area, in one of the nodes. Noticed under the "Volume groups", area that the volumes were named after some loong ID string. Saw there was a "rename" button. figured it would be just like renaming a VM. thigns would just get auto adjusted. but after I renamed to something in english, the cluster is freaking out, "cant find master domain: u'spUUID=xxxxxxx, msdUUID=xxxxxxx' " and under Storage: Storage DOmains, the Data(Master) is down. How can I recover from this ASAP? :-(

New VM from Template and Storage size
by Erez Zarum 16 Jun '20

16 Jun '20

Hey, I have created a template that the disk is a thick (raw) with a size of 15GB. I am trying to create a VM from that template but having the disk with a much larger size, both template and the VM are set to use thick and I create the new VM with the clone option, so there’s no link between the new VM and the template. So far the only solution I managed to find is to adjust the size after creating the VM. For example, this situation causes a problematic step when using Foreman/Satelite as trying to provision a VM based on a template but with different size for the OS disk. I assume that one of the ways to solve it is to convert the template somehow into an “image”? like using OpenStack Glance as a place to store “templates” as images? Any other way besides using Glance? Thanks!

oVirt 4.4 Self-hosted Engine and Intel Skylake CPUs
by Erez Zarum 16 Jun '20

16 Jun '20

Hey, I was trying to install oVirt with SE on a node that has Intel Skylake CPU (Intel Xeon Gold 6238R CPU to be precise) which by Intel supports TSX. When the SE was provisioned as a local VM all was working well, it was using a different CPU type for local provisioning. After the local SE VM was migrated to the shared Storage (iSCSI) and was configured, it failed to start. When checking the XML (and vm.conf) that was created and provided to libvirt I noticed it uses the "Secure Intel Skylake" type CPU with +tsx-ctrl as a required flag. My assumption as this is a fresh install of oVirt with SE is that the newly created Cluster was set to this CPU compatibility. This specific CPU by Intel does not expose any tsx flags, while it does indeed support TSX libvirt has no way of knowing it, more strange, some other CPUs from that same range/models do expose the tsx flag. I have tried to set the kernel cmdline to tsx=yes|auto|off and none of those helped. The quick solution was to start the engine manually by editing the XML file (hosted-engine --vm-shutdown and then start it with libvirt) and change the Cluster CPU type and the HostedEngine CPU type as well to "Intel Skylake" and then start it (hosted-engine --vm-start) Another solution which i haven't tried is to get the correct string from the oVirt-Engine API of the non-secure Intel Skylake CPU and hardcode it into the cpu_model fact in the SE ansible role (task). At the end i opted not to try any workaround and decided to go on with oVirt 4.3 which went smooth, it chose "Intel Skylake Server IBRS SSBD MDS Family" as the Cluster CPU compatibility and installation went without any errors/issues. 1) What will happen if i decide to upgrade to 4.4? I will first have to reinstall a node with CentOS 8 and then migrate the HostedEngine to there as well, will it keep the current cluster CPU type or will it try to upgrade and these fail the upgrade? 2) Are you aware of this situation? I understand this is a new solution because you had to update everytime the CPU databases but on the other hand, Intel is not helping here by not being strict about exposing the tsx flags, perhaps the best will be to let the user chose which CPU type use on the first Cluster created by the SE ansible role? (As far as i remember, this was available in the previous versions of oVirt) Thanks!

Continuing HE install from lost connection
by Glenn Marcy 16 Jun '20

16 Jun '20

I ran the Prepare VM stage of the GUI HostedEngine install and when I came back it had disconnected. Looking at the logs and the current status everything appears to be just fine, but there doesn't seem to be any way in the GUI to continue where it left off. I was wondering if there was some way to provide the hosted_storage information requested in the next panel and complete the installation, perhaps with the command line, instead of redoing all of the work that has already been completed successfully?

Advise Needed - Hosted Engine Minor Update
by jrbdeguzman05＠gmail.com 16 Jun '20

16 Jun '20

Hi Guys! How do you usually backup your hosted engine prior minor updates? I’ve tried to perform a minor update from 4.3.8 to 4.3.9 recently. I’ve used engine-backup before updating and for restore. However, the problem I’m encountering now is that, it looks like the hosted-engine settings are only being restored. The version is still 4.3.9 when I’m trying to revert it to 4.3.8. Am I missing some steps aside from engine-backup —restore? I saw on old posts that snapshots of hosted engine is not a recommended step before upgrade/update. Appreciate your help in advance!

LDAP setup fails on 4.4 reading PEM file
by Stack Korora 15 Jun '20

15 Jun '20

Greetings, I'm having some issues getting LDAP working on CentOS 8 with oVirt 4.4. I would appreciate some help please. When I run ovirt-engine-extension-aaa-ldap-setup I choose "11 - RFC-2307 Schema (Generic)" because that's what my LDAP guy said I should do. :-) Next I select the default Yes for "Use DNS". I select 4 for "Failover between multiple hosts". I put in my two hosts "svr1.my.domain srv2.my.domain". To select the protocol I type "ldaps". To select the method to obtain the PEM I type "File".

When testing the snapshot function of oVirt 4.4, we created snapshot 1 and then snapshot 2, but after clicking the delete button of snapshot 1, snapshot 1 failed to be deleted and the state of corresponding disk became illegal. Removing the snapshot in this state requires a lot of risky work in the background, leading to the inability to free up snapshot space. Long-term backups will cause the target VM to create a large number of unrecoverable snapshots, thus taking up a large amount of production storage.

Ansible ovirt.hosts has no port setting
by Paul-Erik Törrönen 15 Jun '20

15 Jun '20

Running oVirt 4.4. While setting up ovirt with ansible, I noticed that there is no parameter for setting the ssh port of the hosts (which is present if one adds an host on the GUI). I tried adding the port as a part of the address, but that field is apparently evaluated as FQDN only. I did circumvent this by adding FQDN-labeled sections with Port-definition ~/.ssh/config for ovirt-user on the engine-machine (not hosted), but this only got me a step further since the configuration in the engine still is without a port definition and falls back to 22 as a result.

Problem with oVirt 4.4
by minnie.du＠vinchin.com 15 Jun '20

15 Jun '20

We have met a problem when testing oVirt 4.4. Our VM is on NFS storage. When testing the snapshot function of oVirt 4.4, we created snapshot 1 and then snapshot 2, but after clicking the delete button of snapshot 1, snapshot 1 failed to be deleted and the state of corresponding disk became illegal. Removing the snapshot in this state requires a lot of risky work in the background, leading to the inability to free up snapshot space. Long-term backups will cause the target VM to create a large number of unrecoverable snapshots, thus taking up a large amount of production storage. So we need your help.

Engine is one month ahead
by Strahil Nikolov 14 Jun '20

14 Jun '20

Hello All, I have a problem which started after the latest patching 4.3.9 to 4.3.10 . Symptoms so far: 1. Engine reports that Hypervisours are drifting too much 2. ETL service stopped working 3. Web UI constantly notifies me that the nodes are again active (fills the screen till the bottom) So far I have found an issue with one of the Hypervisours and after removing chrony's drift file and reboot - no more issues are observed. I found in the DB that DWH last update was one month (yes, that's July) ahead , so updating it to June has fixed the ETL issue. The problem with the constant "Host has been activated" was fixed by updating the Engine database , table Job (July was changed with June). The only problem I have now is that every event in the Web (and in the DB of course) is pointing to July. Any ideas how the engine is taking the time ,cause a restart doesn't fix the issue? As you can see both Hypervisours and HE VM are OK: [root@engine ~]# ntpdate -q time.cloudflare.com server 162.159.200.1, stratum 3, offset 0.000816, delay 0.02812 server 162.159.200.123, stratum 3, offset 0.000939, delay 0.02834 14 Jun 11:40:05 ntpdate[30135]: adjust time server 162.159.200.1 offset 0.000816 sec [root@engine ~]# logout Connection to engine closed.

ovirt 4.3.10 Web UI constantly "finished activating host"
by Strahil Nikolov 14 Jun '20

14 Jun '20

I'm not sure if this one is related to "time shift" in the DB (as I found that dwh_history_timekeeping had some entries 1 month ahead/ETL service issues also/, but I keep getting spammed that the host has been activated. Any hint ? Best Regards, Strahil Nikolov

oVirt 4.4.0 HE deployment on GlusterFS fails during health check
by Oliver Leinfelder 13 Jun '20

13 Jun '20

Hi, I have the following two components: 1.) A freshly installed VM host (oVirt Node 4.4.0 release ISO) 2.) 3 storage hosts, also freshly installed from oVirt Node 4.4.0 release ISO The storage hosts have been successfully installed with Gluster (through Cockpit). They have two volumes, both of which I can mount and read/write from a client. On the VM host, I ran "hosted-engine --deploy" (no backups imported). When prompted for storage, I answered "glusterfs" and specified "storagehost1:/engine" as storage for the HE deployment. For mount options, I specified "backup-volfile-servers=storagehost2:/engine:storagehost3:/engine" (Not the real hostnames, but all of them are resolvable via internal DNS) Everything seems to works fine, I also see the "engine" volume become populated with data. At some point I could ping and SSH login to the HE. When the setup proceed to health check, it failed and the whole process was aborted :-( "hosted-engine --vm-status" reported "failed liveliness check" when it was reachable via SSH. At some point the engine went down and, to my surprise, shows a grub prompt after the restart when doing a "hosted-engine --console".

Re: oVirt noVNC

Hi Paul, Double checked the permissions as well. All seems to be fine. The only thing that does look different between the environments are the below: ENV1 (Not working) [cid:image001.png@01D640B1.B1BEAA20] ENV2 (Working) [cid:image007.png@01D640B1.E97498D0] It seems that on the working environment, there is a shortcut file (apached-ca.pem) which points to the ca.pem file, but on the environment that is not working, the apache-ca.pem file is not a shortcut. Could this perhaps be an issue?

Hi Anton, Don´t worry, it had me tearing out hair for a while. But, Paul managed to save my remaining hair, so hopefully he has a suggestion that will sort things out for you too 😊 By the way, is Vox using ovirt as their cloud system for customers? Just curious of course.

I double checked the permissions on the cert files now, and they are exactly the same as my other environment. But, the other environment does not have a CA, these are the default certs from ovirt. The other environment is working as expected though. I have checked the websocket service and config, and it seems to be correct. The port is also open on the firewall. I can telnet to my FQDN on port 6100.

Hi Paul, Thanks for the reply. Apologies, I should have added that I have installed our own certificates. The main problem I am facing is that the noVNC console just refuses to open, I get the attached error with any VM I try and access. I should have perhaps started with this issue in my first mail, apologies 😊 Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za From: Staniforth, Paul <P.Staniforth(a)leedsbeckett.ac.uk> Sent: 12 June 2020 10:29 To: users(a)ovirt.org; Anton Louw <Anton.Louw(a)voxtelecom.co.za> Subject: Re: oVirt noVNC Hello Anton, if your organisation has it's own CA you can install your own certificates or get certificates from a trusted CA. https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL.html<https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL.html> Paul S. ________________________________ From: Anton Louw via Users <users(a)ovirt.org<mailto:users@ovirt.org>> Sent: 12 June 2020 08:56 To: users(a)ovirt.org<mailto:users@ovirt.org> <users(a)ovirt.org<mailto:users@ovirt.org>> Subject: [ovirt-users] oVirt noVNC Caution External Mail: Do not click any links or open any attachments unless you trust the sender and know that the content is safe.

PKIX path error
by Stack Korora 11 Jun '20

11 Jun '20

Greetings, I have a running oVirt install that's been working for almost 2 years. I'm building a _completely_ new install. I mention it because it is useful for me to compare configurations when I run into issues like this one. Right now there are three physical hosts: 1x management where I run the engine and db 2x hypervisor nodes. I had it up and installed and running smooth this morning on 4.3.9.4-1.el7 on Scientific Linux 7.8 (fully patched). I copied over our 3rd party certs from the running system and restarted httpd. Perfect. SSL is running! /etc/pki/ovirt-engine/apache-ca.pem /etc/pki/ovirt-engine/certs/apache.cer /etc/pki/ovirt-engine/keys/apache.key.nopass Next I used ovirt-engine-extension-aaa-ldap-setup to point to our ldap server. I did the login and search test and both passed on the command line! Horray! Then I went to the web interface... sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I'm digging through logs and I don't see anything close to this error except nearly the identical message in engine.log. ERROR [org.ovirt.engine.core.aaa.servlet.SslPostLoginServlet] (default task-2) [] server_error: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I can't log in via the web at all, I only get that message (so I can't even test out the local admin). The aaa ldap configuration it generated is darn near perfectly identical (just a name change). The certs are the same. Even when I look in the keystore, the sha1 hashes are the same between the two environments! After over an hour poking at this, I'm completely stumped. Can someone please give me a pointer on what I should try next? Thanks! ~Stack~

Gluster remount?
by Christoph Köhler 11 Jun '20

11 Jun '20

Hey, it happens in our ovirt 4.3.9 occasionally that after reboot one of the dedicated gluster nodes (replica3, arbiter 1) some client connections are missing on server side: # gluster volume status gluvol3 clients Client connections for volume gluvol3 ---------------------------------------------- Brick : glusrv01:/gluster/p1/brick1 Clients connected : 17 Hostname . . . -------------------------------------------- Brick : glusrv02:/gluster/p1/brick1 Clients connected : 15 <---- two connections missing Hostname . . . ---------------------------------------------- Brick : glusrv03:/gluster/p1/brick1 Clients connected : 17 Hostname . . . ---------------------------------------------- I don't know why it happes, the log files don't really help. Now: is there a possibility on the missing nodes to reinitiate the gluster mount like 'mount -o remount' or so? The only way I actually know is to set the concerned node to maintenance and reactivate it. But that is really long-moving with many VMs... Any ideas? Thanks Chris

What happens when shared storage is down?
by Vinícius Ferrão 10 Jun '20

10 Jun '20

Hello, This is a pretty vague and difficult question to answer. But what happens if the shared storage holding the VMs is down or unavailable for a period of time? I’m aware that a longer timeout may put the VMs on pause state, but how this is handled? Is it a time limit? Requests limit? Who manages this? In an event of self recovery of the storage backend what happens next? Manual intervention is required? The VMs may be down or they just continue to run? It depends on the guest OS running like in XenServer where different scenarios may happen? I’ve looked here: https://www.ovirt.org/documentation/admin-guide/chap-Storage.html but there’s nothing that goes about this question. Thanks, Sent from my iPhone

First ovirt 4.4 installation failing
by wart＠caltech.edu 09 Jun '20

09 Jun '20

I'm having some trouble setting up my first oVirt system. I have the CentOS 8 installation on the bare metal (ovirt1.ldas.ligo-la.caltech.edu) the ovirt4.4 packages installed, and then try running 'hosted-engine --deploy' to set up my engine (ovirt-engine1.ldas.ligo-la.caltech.edu) For this initial deployment, I accept almost all of the defaults (other than local network-specific settings). However, the hosted-engine deployment fails with: [ INFO ] TASK [ovirt.hosted_engine_setup : Obtain SSO token using username/pass word credentials] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Wait for the host to be up] [ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 120, "changed": false, "ov irt_hosts": []} [...cleanup...] [ INFO ] TASK [ovirt.hosted_engine_setup : Notify the user about a failure] [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The system may not be provisioned according to the playbook results: please check the logs for the issue, fix accordingly or re-deploy from scratch.\n"} However, when I run 'virsh list', I can still see a HostedEngine1 vm running.

Global Maintenance
by Anton Louw 09 Jun '20

09 Jun '20

Hi Everybody, Just a bit of background. A couple of weeks back I moved my self-hosted engine to a standalone manager. Everything went smooth, my environment is up and running without any issues. Just one thing, when I want to reconfigure settings on my self-hosted engine, it says: "It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode" When trying to enable global maintenance from my node, I also get the below: "Cannot connect to the HA daemon, please check the logs" Is there something I missed when I moved my self-hosted engine to a standalone manager?

Upgrade from 4.3.7 to 4.4 report (through scratch reinstall)
by Gianluca Cecchi 09 Jun '20

09 Jun '20

Just to give a report of final success updating from 4.3.7 to 4.4 one of my home labs, composed by a single host. hw: Intel NUC6i5SY with 32G of ram and 2 SSD disks (250Gb and 500Gb) source sw: oVirt 4.3.7 single host with CentOS 7 OS and storage provided through the host itself via NFS (not officially supported, but working, apart when shutdown needed) Two main VMs to migrate to the new environment: Fedora 30 and Slackware Current (just to not forget the first love... ;-) Exported the VMs to an export storage domain offered through an external USB disk dest sw: oVirt node ng 4.4 configured with HCI single host wizard. Installed on the 250Gb disk. I pre-clean the disks (dd of the first 100Mb of the disks) before install, because during the beta/rc phase I noticed the installer was not so smart to cleanup pre-existing configurations. I had problems in the first run, but with engine cleanup and redeploying it went ok. See here for more details: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/6QODLB6J5Z74YC… I configured the gluster domains in the wizard on the whole second disk. I then imported the 2 VMs without problems. Before starting them up I changed their inherited "BIOS Type" from Legacy to "Default Cluster" and they both started without any problem. While in 4.4 I was able to update Fedora VM from 30 to 31 and then 32 and also refresh the slackware-current one that was about a month behind from latest current. With "Default Cluster" BIOS type the VMs start with the following options: " -machine pc-q35-rhel8.1.0,accel=kvm,usb=off,dump-guest-core=off -cpu Broadwell-noTSX" I was then able to download a CentOS 8 cloud image from the predefined ovirt-image-repository storage domain and convert it to template. Created a VM from this template and cloud-init was able to inject the ssh public key and set timezone. Changed cluster type of ths VM to Default as above with a warning from oVirt but without any problem inside the VM and also changed the disk type from virtio to virtio-scsi without problems. Now I enabled incremental backup at engine level and also at disk level of this CentOS 8 VM so that I can make some tests in this regard. Also, I was able to successfully test the ovirt-ansible-shutdown-env ansible role to make a clean overall shutdown of the environment, one of the things that in my previous unsupported setup was a little cumbersome. Right after install I noticed that in CentOS 8 ovirt-node-ng setup, intel_pstate was the default scaling driver setup, but my cpu was almost always crying with core at 2.6Ghz (and temp around 90 degrees) even if attempted to setup conservative profiles and without nothing running, apart engine VM. The NUC is under my working day table and I don't need always performance from it... So I modified (notice also the rhgb and quite omissions...) these files and reboot: - /etc/default/grub GRUB_CMDLINE_LINUX='crashkernel=auto resume=/dev/mapper/onn-swap rd.lvm.lv=onn/ovirt-node-ng-4.4.0-0.20200521.0+1 rd.lvm.lv=onn/swap intel_pstate=disable' - /boot/grub2/grub.cfg set default_kernelopts="root=UUID=85212719-8feb-43aa-9819-2820d4672795 ro crashkernel=auto ipv6.disable=1 intel_pstate=disable " - /boot/loader/entries/ovirt-node-ng-4.4.0-0.20200521.0+1-4.18.0-147.8.1.el8_1.x86_64.conf options intel_pstate=disable boot=UUID=b717ab4f-ca71-469a-8836-ff92cebc7650 crashkernel=auto rd.lvm.lv=onn/swap root=/dev/onn/ovirt-node-ng-4.4.0-0.20200521.0+1 resume=/dev/mapper/onn-swap rootflags=discard rd.lvm.lv=onn/ovirt-node-ng-4.4.0-0.20200521.0+1 img.bootid=ovirt-node-ng-4.4.0-0.20200521.0+1 null - /boot/efi/EFI/centos/grub.cfg set default_kernelopts="root=/dev/mapper/onn-root ro crashkernel=auto resume=/dev/mapper/onn-swap rd.lvm.lv=onn/root rd.lvm.lv=onn/swap intel_pstate=disable " And now with the default/old scaling driver all is quite silent and still working ok for my needs, with web admin quite usable. I updated my two VMs as described above after cpompleting these changes. Right now for example I have hosted engine running + slackware one + CentOS 8 one with [root@ovirt01 ~]# cat /proc/cpuinfo | grep Hz model name : Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz cpu MHz : 648.431 model name : Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz cpu MHz : 628.307 model name : Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz cpu MHz : 648.859 model name : Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz cpu MHz : 663.792 [root@ovirt01 ~]# and [root@ovirt01 ~# cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor powersave powersave powersave powersave [root@ovirt01 g.cecchi]# Thanks to all that helped throughout ... Cheers, Gianluca

oVirt 4.3 and cinderlib integration (for ceph) on CentOS 7 - centos-release-openstack-pike
by Mathias Schwenke 08 Jun '20

08 Jun '20

At https://www.ovirt.org/develop/release-management/features/storage/cinderlib… ist described the cinderlib integration into oVirt: Installation: - install centos-release-openstack-pike on engine and all hosts - install openstack-cinder and python-pip on engine - pip install cinderlib on engine - install python2-os-brick on all hosts - install ceph-common on engine and on all hosts Which software versions do you use on CentOS 7 whith oVirt 4.3.10? The package centos-release-openstack-pike, as described at the above-mentioned Managed Block Storage feature page, doesn't exist anymore in the CentOS repositories, so I have to switch to centos-release-openstack-queens or newer (rocky, stein, train). So I get (for using with ceph luminous 12): - openstack-cinder 12.0.10 - cinderlib 1.0.1 - ceph-common 12.2.11 - python2-os-brick 2.3.9
