Destroyed VM blocking hosts/filling logs
by davidk＠riavera.com 08 Apr '21

08 Apr '21

Hello, I've somehow gotten one of my VMs stuck in a state that ovirt seems to be rather confused about its existence of now. I'm running oVirt 4.3.10 and using oVirt Node on all the hosts. My engine and host event logs are now filling up very rapidly with this error: VDSM node217 command DestroyVDS failed: General Exception: ("'1048576'",) I was playing with hugetable support, and that error number or string looks suspiciously like the "hugetable size" custom property I set on the VM. This VM was migrated to another host at one point as well, and now that host is also generating the same error as well. When I try to move these hosts to maintenance mode, they get stuck in "Preparing for Maintenance" while it tries to migrate/deal with the VM that's not there any more. Forcibly rebooting the hosts does not change anything. The VM state/host seems to be captured somewhere persistent in this case. The VM in question is not running, and I can start it up on another host successfully, but ovirt still thinks it exists on the other 2 hosts no matter what I do. Is there perhaps some way to delete it from the engine database directly to straighten things out? Here's a dump of the vdsm log on one of the hosts. I haven't been able to pinpoint what the exact issue is or how to fix it, but hopefully someone here will have seen this before? 2021-04-03 04:40:35,515+0000 INFO (jsonrpc/1) [api.virt] START

[ANN] oVirt 4.4.6 Third Release Candidate is now available for testing
by Lev Veyde 08 Apr '21

08 Apr '21

oVirt 4.4.6 Third Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.6 Third Release Candidate for testing, as of April 8th, 2021. This update is the sixth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.6 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.6 (redeploy in case of already being on 4.4.6). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer * oVirt Node 4.4 based on CentOS Linux 8.3 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available for CentOS Linux 8 - oVirt Node NG is already available for CentOS Linux 8 - We found a few issues while testing on CentOS Stream so we are still basing oVirt 4.4.6 Node and Appliance on CentOS Linux.

Q: Sparsify/fstrim don't reduce actual disk image size
by Andrei Verovski 08 Apr '21

08 Apr '21

Hi ! I have VM (under oVirt) with single disk thin provision (~600 GB) running NextCloud on Debian 9. Right now VM HD is almost empty. Unfortunately, it occupies 584 GB (virtual size = 600 GB) All partition (except swap and boot) are EXT4 with discard option. in oVirt “enable discard = on”. # fstrim -av runs successfully: /var: 477.6 GiB (512851144704 bytes) trimmed on /dev/mapper/vg--system-lv4--data /boot: 853.8 MiB (895229952 bytes) trimmed on /dev/mapper/vg--system-lv2--boot /: 88.4 GiB (94888611840 bytes) trimmed on /dev/mapper/vg--system-lv3—sys When fstrim runs again, it trims zero. I even run “Sparsify” in oVirt. Unfortunately, actual size is still 584 GB. Here is /etc/fstab /dev/mapper/vg--system-lv3--sys / ext4 discard,noatime,nodiratime,errors=remount-ro 0 1 /dev/mapper/vg--system-lv2--boot /boot ext2 defaults 0 2 /dev/mapper/vg--system-lv4--data /var ext4 discard,noatime,nodiratime 0 2 /dev/mapper/vg--system-lv1--swap none swap sw 0 0 When disk was partitioned/formatted, swap and boot were created first and positioned at the beginning. What is wrong here? Is it possible to fix all this ? Thanks in advance. Andrei

cannot export - "r.original_template is undefined"
by Diggy Mc 08 Apr '21

08 Apr '21

I cannot export a VM to a data domain. I receive the error: Export VM Failed r.original_template is undefined The VM originated as an OVA provided by a third party. After importing the OVA and customizing the VM, I wanted to export it for backup purposes, but cannot. I am running oVirt 4.4.4. You can download the OVA directly from ERPNext.org if that helps troubleshooting. Download the "Production Image" from here: https://erpnext.org/get-started Any help is appreciated and let me know if additional information is needed.

oVirt longevity after CentOS 8, RHV changes
by David White 08 Apr '21

08 Apr '21

I'm replying to Thomas's thread below, but am creating a new subject so as not to hijack the original thread. I'm sure that this topic has come up before. I first joined this list last fall, when I began planning and testing with oVirt, but as of the past few weeks, I'm paying closer attention to the mailing list now that I'm actually using oVirt and am getting ready to deploy to a production environment. I'll also try to jump in and help other people as time permits and as my experience grow. I echo Thomas's concerns here. While I'm thankful for Red Hat's gesture to allow people to use up to 16 Red Hat installs at no charge, I'm concerned about the longevity of oVirt, now that Red Hat is no longer going to support RHV going forward. What is the benefit to Red Hat / IBM of supporting this platform now that it is no longer being commercialized as a Red Hat product? What is to prevent Red Hat from pulling the plug on this project, similar to what happened to CentOS 8? As a user of oVirt (4.5, installed on Red Hat 8.3), how can I and others help to contribute to the project to ensure its longevity? Or should I really just go find an alternative in the future? (I had been planning to use oVirt for a while, and did some testing last fall, so the announcement of RHV's (commercial) demise was poor timing for me, because I don't have time to switch gears and change my plans to use something else, like Proxmox or something. From what I've seen, this is a great product, and I guess I can understand Red Hat's decision to pull the plug on the commercial project, now that OpenShift supports full VMs. But my understanding is that OpenShift is a lot more complicated and requires more resources. I really don't need a full kubernetes environment. I just need a stable virtualization platform.

New Management VLAN for hyperconverged cluster
by David White 08 Apr '21

08 Apr '21

I'm working on setting up my environment prior to production, and have run into an issue. I got most things configured, but due to a limitation on one of my switches, I decided to change the management vlan that the hosts communicate on. Over the course of changing that vlan, I wound up resetting my router to default settings. I have the router operational again, and I also have 1 of my switches operational. Now, I'm trying to bring the oVirt cluster back online.This is oVirt 4.5 running on RHEL 8.3. The old vlan is 1, and the new vlan is 10. Currently, hosts 2 & 3 are accessible over the new vlan, and can ping each other. I'm able to ssh to both hosts, and when I run "gluster peer status", I see that they are connected to each other. However, host 1 is not accessible from anything. I can't ping it, and it cannot get out. As part of my troubleshooting, I've done the following: From the host console, I ran `nmcli connection delete` to delete the old vlan (VLAN 1). I moved the /etc/sysconfig/network-scripts/interface.1 file to interface.10, and edited the file accordingly to make sure the vlan and device settings are set to 10 instead of 1, and I rebooted the host. The engine seems to be running, but I don't understand why. From each of the hosts that are working (host 2 and host 3), I ran "hosted-engine --check-liveliness" and both hosts indicate that the engine is NOT running. Yet the engine loads in a web browser, and I'm able to log into /ovirt-engine/webadmin/. The engine thinks that all 3 hosts is nonresponsive. See screenshot below: [Screenshot from 2021-04-07 17-33-48.png] What I'm really looking for help with is to get the first host back online. Once it is healthy and gluster is healthy, I feel confident I can get the engine operational again. What else should I look for on this host? Sent with ProtonMail Secure Email.

How to restore Storage Domain from disaster recovery
by miguel.garcia＠toshibagcs.com 07 Apr '21

07 Apr '21

My engine drop dead so had to create a new one and I'm trying to recover virtual drives from previous engine. I'm using next instructions to import storage domain https://www.ovirt.org/develop/release-management/features/storage/importsto… but in order to do it well need to unattach storage domain from previous engine which that is not possible right now since the engine has died. Anyway discarting requirements I got the following warning message: This operation might be unrecoverable and destructive! Storage Domain(s) are already attached to a Data Center. Aproving this operation might cause data corruption if both Data Centers are Active. Do you have an idea how to deactivate a Storage domain without ovirt-engine? Is there any chance to export virtual drives as backups without engine? Thanks in advance.

oVirt 4.4.4 not dislaying Sign-on Screen
by louisb＠ameritech.net 07 Apr '21

07 Apr '21

I recently installed oVirt 4.4.4, everything appeared to run successfully, however, I’m unable to get the sign-on screen to display on my RHEL 8.3 machine. I did do an install using the remote database installation. I encountered no issue with the install, I can see the “engine” and “ovirt_engine_history” in PostgreSQL 13.3. The tables and table spaces have all been created as designed by the installation process. When I enter the URL that was displayed once the installation completed I get the following information displayed on the screen: Internal Error I’ve tried using the port 443 and port 80 URL and get the same results. The URL are as follows: http://WorkstationName:80/ovirt-engine https://WorkstationName:443/ovirt-engine For three days I’ve been trying to locate logs that will help me located and resolve the problem, but so far I’ve had no luck. Can anyone tell where I should start looking to resolve my issue? I’ve checked several system logs and logs for Apache with luck. What should I be looking for within the logs? What logs should I be looking at? I don’t believe my issue is with the back-end database, I thinks its something with Apache not being able to find the web pages to display. How can I start to investigate my problem an develop a solution? My Linux/RHEL 8.3 OS has all of the latest patches and fixes applied. Thanks

Experience on using HCI with geo-replication for DR
by wodel youchi 07 Apr '21

07 Apr '21

Hi, Does anyone use ovirt HCI with geo-replication for DR? if yes, could you share your experience? We recently did a setup of 2 HCI platforms, and we configured geo-replication between them. The two platforms were configured with encryption and VDO. When testing the DR, we had some surprises : - Sometimes VMs are not imported - Sometimes some VMs are imported others not - Sometimes VMs are imported without their disks - Sometimes deleted items from the source are imported!!! - And sometimes the imported VMs are corrupted.
