Gluster Volume Type Distributed
by Dominique Deschênes
Hi Everyone,
I would like to use Distrbuted Volume type but the volume type is Gray out. I can only use the replicate type.
It's normal ?
3 ovirt Servers 4.4.1-2020080418
Can I configure a replicate volume for the engine domain and Distributed for the data domain?
Thank you

Failed to connect to the hypervisor
by Eugène Ngontang
Hi,
I'm facing a strange issue with ovirt host.
I can't list nodes status running virsh, vdsdm seems bad.
I can't even delete the hosted engine, nor ping it, but I can still access
my infra vm inside it[image: 😉]

Have you guys ever faced this issue?
How can I access VM inside my virtual data center while the VM Manager is
broken?
Any solution to work around this please?

Compatibilty issue
by carl langlois
Hi,
I have upgraded ovirt to 4.3 and now I have some vm that I can start

state but if i try to run it I get this message.
Cannot run VM. The Custom Compatibility Version of VM vmfpgatest (4.2) is
not supported in Data Center compatibility version 4.3.
any suggestions?

TroubleshootingoVirt Node deploy FQDN not reachable
by David White
In a recent thread, Roberto mentioned seeing the error message "FQDN Not Reachable" when trying to deploy oVirt Node 4.4.1, but was able to get past that error when using ovirt-node-ng-installer-4.4.2-2020080612.el8.iso.
I experienced the same problems on oVirt Node install 4.4.1, so I tried the latest release of 4.4.2. When that failed, I went back and installed from the exact same image as Roberto said worked on the 4.4.2 branch: ovirt-node-ng-installer-4.4.2-2020080612.el8.iso
Unfortunately, that's still not working for me - so that tells me I'm probably doing something wrong.
Given the following facts:
[root@dev1-centos ~]# hostname
dev1-centos.office.barredowlweb.com
[root@dev1-centos ~]# host dev1-centos.office.barredowlweb.com
dev1-centos.office.barredowlweb.com has address 192.168.2.96
I am trying to install oVirt using the Hyperconverged Gluster Wizard for a Single Node.
In the "Host1" box, I enter the full hostname: dev1-centos.office.barredowlweb.com
And that's when I get the FQDN error message.
Am I missing something here?

Is the Hosted Engine setup finished + Can't connect vdsm storage
by Bielej SRE
Hi,
We have 6 node oVirt setup with Compatibility version 4.3 running on CentOS 7.6.1810
Recently We have found out some very interesting log entries on a few of our nodes.
/var/log/ovirt-hosted-engine-ha/broker.log:

/var/log/messages

We have inherited that setup from the previous team but I'm fairly certain the the Hosted Engine setup is finished.
Also, this line is not present on all hosts.
Should We worry about ovirt-ha-broker service not running on some hosts?

Currently the hosted engine VM is running on host26.
I'd be very grateful for any help.

Host has no default route
by Wesley Stewart
I am trying to add a host to a single host cluster. Everything has gone
pretty well so far, except when the host gets to the end of the
installation process, I see an exclamation mark indicating "Host has no
default route".
The installation "finishes" and the host goes into a non-responsive state.
I am not really sure where to check. I get a:
host *name* installation has failed. Network error during communication
with host.
Running 4.3.6
Thanks!

LDAP/AD issue
by kim.kargaard＠noroff.no
Hi all,
We have had our ovirt instance connected to our internal AD for users to log into the VM portal for the last year, linked to studentdomene.noroff.no. This has been working without any problems. We had it set up and the DNS server had a forward record to the DC's. All good.
Then, of course, the institution decided to introduce student emails and they decided to add the domain stud.noroff.no for student emails and made this the primary domain in the AD. The problem is that when this is changed, students can no longer log into the engine. I have of course changed the ldap settings and added a forward record on the DNS to the new domain. However, it seems that the domain is studentdomene.noroff.no, but with an added UPN suffix with stud.noroff.no
When students try to log in, with the config changes, they get this error in the browser:
server_error: An error occurred while attempting to query DNS in order to retrieve SRV records with name '_ldap._tcp.stud.noroff.no': NameNotFoundException(DNS name not found [response code 3]), ldapSDKVersion=4.0.7, revision=b28fb50058dfe2864171df2448ad2ad2b4c2ad58
Any ideas on how to solve this issue?
My config looks like this:
sudo cat /etc/ovirt-engine/aaa/Students.properties
[sudo] password for noroffadmin:
include = <ad.properties>
vars.domain = studentdomene.noroff.no
vars.user = CN=ovirt auth,CN=Users,DC=stud,DC=noroff,DC=no
vars.password = PASSWORD
pool.default.auth.simple.bindDN = ${global:vars.user}
pool.default.auth.simple.password = ${global:vars.password}
pool.default.serverset.type = srvrecord
pool.default.serverset.srvrecord.domain = ${global:vars.domain}
my forward on the DNS server looks like this:
sudo cat /etc/named/named.conf.local
[sudo] password for noroffadmin:
zone "platform.noroff.no"{
type master;
file "/etc/named/zones/db.platform.noroff.no"; # zone file path
};
zone "stud.noroff.no" {
type forward;
forward only;
forwarders { 172.24.111.20; 172.27.111.20; 172.21.111.20; 172.16.111.20; };
};
zone "studentdomene.noroff.no" {
type forward;
forward only;
forwarders { 172.24.111.20; 172.27.111.20; 172.21.111.20; 172.16.111.20; };
};
zone "122.16.172.in-addr.arpa" {
type master;
file "/etc/named/zones/db.122.16.172"; # 172.16.122.0/24 subnet
};
Any pointers would be greatly appreciated :)

oVirt SHE smart-automated backup
by Vrgotic, Marko
Dear oVirt,
For a while now I have been running backup of oVirt engine via ansible. And that works just fine.
However, its still recommended, in SHE HA environment, especially for Restore purpose to have one of HA nodes in Maintenance mode, clean from Virtual load.
Has anyone so far been able to automate oVirt engine backup in following or similar way:
1. Register on which HA node is SHE atm
2. Pick the other HA node to go into maintenance mode – in order to have one of HA nodes without virtual load
3. Verify it’s in maintenance mode
4. Execute engine-backup
5. Remove the maintenance mode of the node from step 2
Even if you are half way through, I would be happy to get involved and contribute.
Kindly awaiting your reply.
