Importing Storage Domain's Export from one Data Center to Another Data Center
by calebmibaker＠outlook.com 09 Oct '24

09 Oct '24

Is it possible to perform disaster recovery importing a Storage Domain's Export from one Data Center to another in a manually fashion without Ansible? I'm trying to import Data Center 1's Storage Domain Export by cloning the storage domain export and importing it into Data Center 2's environment through IP address & NFS name within the oVirt's web portal. However, I receive this error message: there is no storage domain under the specified path. Below is what I have done to tried to troubleshoot the issue. After looking into the documentation, I haven't seen information for this method. Should I consider another option? Is there a preferred way of testing DR within an environment? Thank you. -I have detach both of the export storage domains from both data centers before importing the cloned export. -Changing import settings -I have adjusted the metadata information within the cloned export after mounting it and reviewing the logs.

iSCSI Storage Issue - move Hosts!?
by steve-pa＠hotmail.com 09 Oct '24

09 Oct '24

Hello everyone, I am currently trying to set up my VM environment again. Status now: Host1 + iSCSI storage connection Plan: Host2 + same iSCSI storage as above Now i want to move all VMs to Host2, Host2 is already included and I can start all VMs on Host2. Problem: Storage -> Manage Domain: Host1 is connected to the storage here. I have no possibility to switch to Host2. What happens if I now put Host1 into maintenance mode or delete it completely? Will all my systems then crash because the storage connection has been lost?

Installing on iSCSI boot node
by rtartar＠gmail.com 30 Sep '24

30 Sep '24

I've installed the oVirt node on iSCSI boot server (Cisco UCS chassis) But when I go to add to the manager it fails and the Node loses contact with it's ibft interface. Anyway I can leave the interface alone when adding to the manager? I have 5 physical interfaces attached to the node. Any help would be greatly appreciated. Using the node 4.5 installer. I add the ip=ibft to the installation startup and seems to work mostly... Thanks in advance

Hello Marcos, I followed the guide and the suggestions provided by Ovirt Documentation. I didn't do any customisations, and it is a clean installation. How I can solve this? It seems there is a problem in normal installation process. Can you support? Thanks, Devis

Hi, I followed guide to install the oVirt Engine. I also used the suggestion to use oVirt master snapshot repositories. But during the installation I obtain the following error: "The host has been set in non_operational status, deployment errors: code 154: Host ********* is compatible with versions (4.2,4.3,4.4,4.5,4.6,4.7) and cannot join Cluster Default which is set to version 4.8., code 9000: Failed to verify Power Management configuration for Host *******., fix accordingly and re-deploy."} How I can solve this problem? I cannot find any suggestion on internet.

oVirt Node 4.5.5 no virtualization tab
by arkansascontrols＠icloud.com 26 Sep '24

26 Sep '24

I have installed 4.5.5 and can get to the Web Interface at :9090 on all 3. I have been able to add the SSH keys and from any of the 3 hosts web interface I can get to the others from the drop down. But there is no Virtualization Tab on any of the 3, so no way to create VM's. I have followed a few instructions from some threads I've found on here https://www.ovirt.org/dropped/gluster-hyperconverged/chap-Deploying_Hyperco… I subscribed all 3 hosts to the repo, and installed the engine, but the cockpit-ovirt-dashboard doesn't exist to install, and I'm guessing that's where I will find what I need to make this usable. Any help would be appreciated.
