Adding a Ubuntu Host's NFS share to oVirt
by David White
Hello,
Is it possible to use Ubuntu to share an NFS export with oVirt?I'm trying to setup a Backup Domain for my environment.
I got to the point of actually adding the new Storage Domain.
When I click OK, I see the storage domain appear momentarily before disappearing, at which point I get a message about oVirt not being able to obtain a lock.
It appears I'm running into the issue described in this thread: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/BNVX.... Although the actual export is ext4, not xfs.
From what I'm reading on that thread and elsewhere, it sounds like this problem is a result of SELinux not being present, is that correct?
Is my only option here to install an OS that supports SELinux?

I think you can download and install the ovirt-engine-appliance rpm (the big one) from https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/x86_64/
in advance.

Hello,
I am trying to test oVirt node 4.4.6 inside my company’s network which needs proxy setting for internet access.
Is there any possibility to deploy host engine without any internet access? i.e. Is offline deployment of hosted engine possible?
I have added the following line at the end of the file /usr/share/ovirt-hosted-engine-setup/ansible/trigger_role.yml
environment:
https_proxy: "http://<proxy_host>:<proxy_port>"
http_proxy: "http://<proxy_host>:<proxy_port>"
But it gives error in the process of “hosted-engine --deploy”. I am not sure if this a typical issue in my company’s network but, it would be great if there is any offline installation method (without accessing internet repository).
I have also tried to use “hosted-engine --deploy --ansible-extra-vars=he_offline_deployment=true” but, it is not helping me at all.
With regards

Can't remove snapshot
by David Johnson
Hi all,
I patched one of my Windows VM's yesterday. I started by snapshotting the
VM, then applied the Windows update. Now that the patch has been tested, I
want to remove the snapshot. I get this message:
Error while executing action:
win-sql-2019:
- Cannot remove Snapshot. The following attached disks are in ILLEGAL
status: win-2019-tmpl_Disk1 - please remove them and try again.
Does anyone have any thoughts how to recover from this? I really don't want
to keep this snapshot hanging around.
Thanks in advance,
*David Johnson*

Thanks, I'll check it out.
Since my business is replatforming and transforming databases, digging
around the DB is something I will be very comfortable with.
I won't be able to do anything until Friday. I'll let you know how it goes.

Hi Strahil,
Can you respond to the thread? Luckily for me, I don't deal with
glusterFS so much :)

Cannot add new host to Ovirt
by pablo＠miami.edu
I have an Ovirt installation with a hosted engine and three hosts. Using Gluster as the storage for the VMs.
Ovirt: 4.4.6.7
Hosts: CentOS Stream release 8 (updated to latest)
So far so good.
I am trying to add a new host to the cluster with the same OS and hardware as the others and I cannot get it to install, it gives me all kind of errors and it will not install.
I reinstalled the OS and I am getting the same results.
DNS is configured properly and working ok for all hosts.
I can see this error in this log file ansible-runner-service.log:
2021-05-30 15:46:38,319 - runner_service.services.hosts - ERROR - SSH - NOAUTH:SSH auth error - passwordless ssh not configured for 'ovirt4'
(sshd is configured exactly the same as all other hosts and I can login to this host without a password from the ovirt hosted engine)
I see these errors in the log engine.log:
2021-05-30 16:22:35,166Z ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.Reactor] (SSL Stomp Reactor) [] Unable to process messages PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I tried reinstalling, rebooting, put it in maintenance, enroll the certificate, check for Upgrades, rebooted multiple times both the hosts and the ovirt engine:
nothing works.
What am I doing wrong?
Thank you in advance for your help.
