I've initiated this mail communication for the very first time. Recently,
I've started using *oVirt-Engine* & *oVirt-Node* in my lab as I want to
host a openstack kind of infrastructure hosting environment for my company.
Prior to that, I'd like to get information on the below listed statement.
I've created data domain, iso domain & export domain over the NFS.
Now, my VM is created by loading CentOS 7.9 ISO from "iso domain" & storing
"VM" data on "data domain".
Here, I'm just curious to know about the NFS efficiency to manage VMs
because the OS boots/loads from remote "NFS Data Domain", not from the
local storage (i.e. oVirt-Node)
Which is more efficient? NFS or iSCSI for VM Hosting?

I have 2 oVirt 3 node Clusters in 2 Datacenters - effectively 2 independent environements with stretched VLANs for DR purposes.
Each volume is geo replicated to the other datacenter. Each volume is a separate Storage Domain.
In a DR event the geo-replicated volumes/Storage Domains are imported in the other Datacenter and the VMs imported once it's attached.
The issue I am seeing is that some of the VMs are not listed when I click 'VM Import' from the imported Storage Domain. The disks for those missing VMs however, do exist in 'Disk Import' Tab of the imported Storage Domain.
Prior to importing the Storage Domain in Site B, all VM disks were migrated to a single Storage Domain in Site A and geo-replication allowed to sync.
I have a fresh Ovirt installation (220.127.116.11-1.el8 engine and oVirt Node
4.4.10) on a Dell VRTX chassis. There are 3 blades, two of them are
identical hardware (PowerEdge M630) and the third is a little newer
(PowerEdge M640). The third has different CPUs, more RAM, and slower
NICs. I also have a bunch of data domains some on the shared PERC
internal storage and others on an external iSCSI storage, all seems
configured correctly and all the hosts are operational.
I can migrate a VM back and forth from the first two blades without any
problem, I can migrate a VM to the third blade but when I migrate a VM
from the third blade to any of the other two the task terminate
successfully, the VM is marked as up on the target host but the VM
hangs, the console is frozen and the VM stops to respond to ping.
I have no clues about why this is happening and I'm looking for
suggestions about how to debug and hopefully fix this issue.
Thanks in advance

I tried to upload .iso files but the status was "Paused by the system" and was waiting 15 hours for the status to change but still no changes, i tried to delete the .ISO file but i can't remove at all, its status was "Finalizing cleaning up" i waited 20 hours for the status to change but with no success. Kindly guard me through the process to fix this errors, so I can upload .ISO files to the Disk to launch the VM successfully. Please see below picture for the error.
When the system pauses an upload, you can cancel the upload from the
Storage > Disks > Upload > Cancel
This will delete the new disk and end the image transfer.
To understand why the system paused the transfer, please share more info:
- Which oVirt version are you running?
- Did you add the engine CA certificate to the browser?
You can check if the browser is configured correctly by opening an
Storage > Disks > Upload > Start
and clicking the "Test Connection" button. If this fails, you need to
add the engine
CA to the browser. When "Test Connection" is successful, try to upload again.
If the upload fails again, please share logs showing the timeframe of
- engine log from /var/log/ovirt-engine/engine.log
- vdsm log from the host performing the upload (see the events tag in
engine UI) from /var/log/vdsm/vdsm.log
- ovirt-imageio log from the host performing the upload from

Hi ovirt list,
I need help.
I ran “dnf update” on my engine and reboot it. Then I lost connection of the engine.
When I access one of my host web management https://ovirthost1:9090, I saw engine status is “Hosted Engine is up!”, but another host of the cluster is in down status.
How can I bring up my engine since it is “UP” now.

Thanks David, I didn't see your e-mail while I was writing my answer.
I confirm I went a similar way (but passing anyway from OVA and then
extracting the disk...)
