ovirt-engine certificate renewal
by bill.hong＠neurogine.com 03 Jan '24

03 Jan '24

Hi, I'm running ovirt Version 4.5.3.2-1.el8 with 1 + 3 nodes setup. Currently i'm encountering this issue of ovirt-engine portal certificate which has already expired. "PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed " I'm aware of the solution by running "engine-setup --offline" to renew the cert. (https://yaohuablog.com/zh/ovirt-engine-upgrade-web-certificate) However my host machine has this problem with the psql command issue whenever i run the engine-backup. [root@server1~]# engine-backup --mode=backup Start of engine-backup with mode 'backup' scope: all archive file: /var/lib/ovirt-engine-backup/ovirt-engine-backup-20240103163047.backup log file: /var/log/ovirt-engine-backup/ovirt-engine-backup-20240103163047.log psql: /lib64/libpq.so.5: no version information available (required by psql) psql: /lib64/libpq.so.5: no version information available (required by psql) psql: /lib64/libpq.so.5: no version information available (required by psql) Backing up: psql: /lib64/libpq.so.5: no version information available (required by psql) psql: /lib64/libpq.so.5: no version information available (required by psql) psql: /lib64/libpq.so.5: no version information available (required by psql) Notifying engine - Files - Engine database 'engine' Notifying engine FATAL: Database engine backup failed [root@server1~]# dnf module list postgresql Last metadata expiration check: 1:55:29 ago on Wed 03 Jan 2024 02:38:30 PM +08.

Should i fix the psql error first ? If i just want to renew my certificate , will the psql error cause me to fail to renew the cert in the "engine-setup --offline" command ? 2. What if after the "engine-setup --offline" failed to renew will my running VM be affected and down ? will there be any recovery method later ? will the reinstallation work on stand-alone machine ?

Hello All User At Ovrit, We are using a Ovrit 4.5 Stable version set of 3 physical server as cluster in to 3 setup. As we have migrated from Ovirt 4.2 to 4.5 version, our hardware are already got out warranty and our management don’t to refresh the hardware. Where they have ask us to migrated running VM’s on our infra to “MS Azure Cloud Migration” As Microsoft say in they KB (https://learn.microsoft.com/en-us/azure/site-recovery/migrate-tutorial-on-p… methods where Ovirt/RHV is not listed. We have try one test vm from out Ovirt infra to MS Azure Cloud Migration. Which get show migrated but after that server don’t boot up we have mostly mix of Linux(CentOS/Ubuntu)/Windows. Is any one has migrated Ovirt host vm’s to MS Azure Cloud Migration Regards Techieim.

DR plan
by 2707974＠gmail.com 28 Dec '23

28 Dec '23

Hi All, We wish to create some kind of DR plan for our OVM 4.4.10.7-1.0.22.el8 environment. Idea is to do storage replication of defined Storage Domains. steps: create LUN on storage present LUN to OVM create Storage Domain put VMs on Storage Domain on storage replicate LUN to another storage [or the same storage] Storage Domains contains OVF_STORE Now, recovery On live OVM present replica of LUN import Storage Domain But we cannot import replica LUN. Where to look for errors? Is this action possible it all? Facts OVM is the same version Storage is the same vendor LUN is browsable on SAN level and have differen WWIN, if we wish to add replicated LUN like new Storage Domain. Adding new Storage Domain mean that LUN will be formatted ... What I do wrong?

Re: How to restore VMs from shared storage domain when HE and VMs are not accessible?
by Jorge Visentini 27 Dec '23

I'm not sure, but... maybe: 1 - Import the Shared Domain Storage 2 - Export the data (VMs/Disks) to a mount point 3 - Create a Local Storage (the Cluster will changed) 4 - Import the data (VMs/Disks) to a Local Storage.

[ovirt4.4][rockylinux8.9][tg3] Communication down between engine and host after setting up network
by Cyril VINH-TUNG 27 Dec '23

27 Dec '23

Dear all I have an issue with ~same environment~ to make tg3 nic communicate between rocky linux 8.9 oVirt 4.4 engine and rocky linux 8.9 fresh installed host. Thanks to this post (https://forums.centos.org/viewtopic.php?t=65299) I had to make the ifcfg simplications to make engine communicate with the host and therefore be able to install the host via ovirt web UI. Then after setting up the network via ovirt and reboot the host, I lost the communicatiin between ovirt engine and the host (even ping does not work). Note that I have a virtualized pfsense between engine and host. All firewalls are opened. From anywhere else than the engine subnet I can communicate with the host and the engine can also communicate with any device on the same subnet than the host... so my thought is that there might be some incompatible parameter between pfsense and the host.... but then 'why did it work before the vdsm installation ? :-/ ). This last fact makes me think that it's a vdsm/nmstate/ethtool parameter that I have to tune... Any help would be much appreciated... (host is a hp proliant DL360 with tg3 3.137 module coming from base rocky linux) [code] filename: /lib/modules/4.18.0-513.9.1.el8_9.x86_64/kernel/drivers/net/ethernet/broadcom/tg3.ko.xz firmware: tigon/tg3_tso5.bin firmware: tigon/tg3_tso.bin firmware: tigon/tg3.bin version: 3.137 license: GPL description: Broadcom Tigon3 ethernet driver author: David S.

[oVirt 4.4][RockyLinux 8.9] Engine loses connectivity with freshly installed hosts after network setup

Re: How to restore VMs from shared storage domain when HE and VMs are not accessible?

Hi, First of all, recreate the engine VM using your backup or starting from scratch. Then, just import the domain storages and your VMs will be there. Cheers!

Creating snapshots of Windows VM result in Status Code: 500
by Jon Sattelberger 22 Dec '23

22 Dec '23

I receive a "Status Code: 500" popup whenever I attempt to create a snapshot for a Windows VM from the Administration Portal UI. It doesn't matter if the VM is powered on or off. Nor the OS designation set in the UI (setting Linux or Other...). The modal usually states: "Operation Canceled" followed by "Error while executing action: A Request to the Server failed with the following Status Code: 500" or "Error while executing query: null". There are at least a dozen popups, and will continue to repeat every few seconds. The snapshot tab in the Admin Portal UI will then have issues displaying the Active VM and the newly created snapshot entry. If you try to examine both entries, the disk, network, and installed applications might appear blank. The web inspector will usually contain the following: Fri Dec 22 09:43:07 GMT-500 2023 org.ovirt.engine.ui.frontend.Frontend SEVERE: Failed to execute runQuery: com.google.gwt.user.client.rpc.StatusCodeException: 500 Internal Server Error The call failed on the server; see server log for details com.google.gwt.user.client.rpc.StatusCodeException: 500 Internal Server Error The call failed on the server; see server log for details The engine logs will have: File: server.log 2023-12-22 09:43:04,387-05 ERROR [io.undertow.servlet] (default task-726) Exception while dispatching incoming RPC call: com.google.gwt.user.client.rpc.SerializationException: Can't find the serialization policy file. This probably means that the user has an old version of the application loaded in the browser. To solve the issue the user needs to close the browser and open it again, so that the application is reloaded. ... snip ... Caused by: com.google.gwt.user.client.rpc.SerializationException: Type 'org.ovirt.engine.core.common.utils.SecretValue' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized.: instance = *** The same snapshot will appear fine in the VM Portal. I am able to see the network interfaces, and disks. No issues creating a snapshot of a Linux-based VM from either UI interfaces. I've tried in both Firefox (115.5 ESR) and Google Chrome (latest-ish). Any thoughts on where to look next? Version 4.5.6-0 (git12af746179.el8) on RHEL 8. Thank you, Jon
