data storage domain iso upload problem
by csabany＠freemail.hu
Hi,
I managed a ovirt 4.4.7 for production systems.
Last week i removed the Master storage domain (moved tamplates, vm-s well, unattached, etc), but i forgot to move isos.
Now, when i upload a new iso to a data storage domain, the system show it, but it's unbootable:
"could not read from cdrom code 0005"
thanks

Change Cluster CPU type
by Andrey Rusakov
We are using oVirt for several years.
And we start with Xeon v2 CPUs.
At this moment of time we got all v3 aтв we will chnage them to v4 in a month.
So i would like to change Cluster default CPU to Haswell, But got error with custom cpu on HostedEngine.
HostedEngine config is locked.
Is there a solution to chnage HostedEngine cpu type?
P.S. some problem with Cluster compability version (4.5 4.6)

NFS storage was locked for 45 minutes after I attempted a clone operation
by David White
I have an HCI cluster running on Gluster storage. I exposed an NFS share into oVirt as a storage domain so that I could clone all of my VMs (I'm preparing to move physically to a new datacenter). I got 3-4 VMs cloned perfectly fine yesterday. But then this evening, I tried to clone a big VM, and it caused the disk to lock up. The VM went totally unresponsive, and I didn't see a way to cancel the clone. Nagios NRPE (on the client VM) was reporting server load over 65+, but I was never able to establish an SSH connection.
Eventually, I tried restarting the ovirt-engine, per https://access.redhat.com/solutions/396753. When that didn't work, I powered down the VM completely. But the disks were still locked. So I then tried to put the storage domain into maintenance mode, but that wound up putting the entire domain into a "locked" state. Finally, eventually, the disks unlocked, and I was able to power the VM back online.
From start to finish, my VM was down for about 45 minutes, including the time when NRPE was still sending data to Nagios.
What logs should I look at, and how can I troubleshoot what went wrong here, and hopefully avoid this from happening again?

Template for Ubuntu 18.04 Server Issues
by jeremy_tourville＠hotmail.com
I have built a system as a template on oVirt. Specifically, Ubuntu 18.04 server.
I am noticing an issue when creating new vms from that template. I used the check box for "seal template" when creating the template.
When I create a new Ubuntu VM I am getting duplicate IP addresses for all the machines created from the template.
It seems like the checkbox doesn't fully function as intended. I would need to do further manual steps to clear up this issue.
Has anyone else noticed this behavior? Is this expected or have I missed something?
Thanks for your input!

Hi Dominique,
Hope you are doing well
In order to investigate this, we need to check the log files
Can you please try to do import again and provide the following log files after the import:
- engine.log, from location: <deployment_location>/var/log/ovirt-engine/engine.log
- ansible log file (depending on the time of the import), from location: <deployment_location>/var/log/ovirt-engine/ova
Thanks,
Saif

Re: [External] : Re: about the hugepage setting of the KVM server
by Tommy Sway
I use the ovirt-node, and I configured HUGEPAGE on the VM, and does not
configure the HUGEPAGE on the KVM host.
The THP I don't configure anything about it, and after configure the
HUGEPAGE on the vm, there is no report.
I don't know which method is the best.

Hi Tommy,
I have no simple answer to your question since I did not need this before,
but some questions may help us understand how it is currently working.
1st- Are you using an ovirt-node or an OS+vdsm as a hypervisor?
2nd- Did you enabled huge pages on the VM OS?
3rd- Did you check on the hypervisor OS if transparent hugepages (THP) is
enabled? And if, after enabling/configuring hugepages in the VM, it is
reporting hugepages are in use in the host?

Subject: [ovirt-users] about the hugepage setting of the KVM server
Hi:
I am running virtual machines on the KVM servers of oVirt env. The virtual
machine is running database, which needs to set the memory huge page on the
OPERATING system of the virtual machine.
If I need to set the huge page on the VIRTUAL machine, do I also need to set
huge page on the KVM physical machine? Or just on the virtual machine?
What best practices do you recommend?
Thank you very much!

Unable to export VM from data storage domain.
by Diggy Mc
I'm running oVirt 4.4.4 with two data storage domains. One domain is where the production VMs run. The second domain is where I make backup copies of the VMs in the event of problems with the main production VMs. I make backups using the export option from the GUI's dropdown list.
I just now tried to "restore" a backup copy via the export function and get an error. In fact, I get errors trying to export (import to my original data domain) any of the VMs that were exported to my backup data domain. My backup domain is a DATA domain and not an EXPORT domain.
The exact error is:
Export VM Failed
[Cannot add VM. Cannot find a disk profile defined on storage domain 246c69e9-6f16-489f-8022-8613f6c1c22a.]
Is this a bug or am I doing something wrong? Help is needed urgently. In advance, thank you.
