ovirt 4.4 self-hosted deployment questions
by Michael Thomas
I have not been able to find answers to a couple of questions in the
self-hosted engine documentation[1].
* When installing a new Enterprise Linux host for ovirt, what are the
network requirements? Specifically, am I supposed to set up the
ovirtmgmt bridge myself on new hosts, or am I supposed to let that be
handled by the engine when I add the new host to the engine?
* In the 'New Host' dialog on the engine management page, does the
Hostname/IP that I enter have to be the host's name on the ovirtmgmt
LAN? If so, then it seems to me that I need to configure the ovirtmgmt
bridge myself on new hosts.
* Does the engine need to be able to route outside of the cluster (eg to
the WAN), or is it allowed to restrict the engine's routing to the local
cluster?
* In the 'New Host' dialog on the engine management page, what is the
meaning of 'Choose hosted engine deployment action'? From the way it is
phrased, it sounds like this will create a second engine in my cluster,
which doesn't make sense. Or does this mean that the new host will be
able to run the Engine VM in a HA manner?
In my current test deployment I have 3 subnets in my cluster. Network
WAN is the WAN. Network CLUSTER is for communication between cluster
compute nodes, storage servers, and management servers. Network OVIRT
is for ovirt management and VM migration between hosts.
My first self-hosted engine host is connected to networks CLUSTER and
OVIRT. The engine VM is only connected to network OVIRT through a
bridge on the host, but has a gateway that lets it route traffic to
network CLUSTER (but not network WAN).
Is this an appropriate network setup for ovirt, or should there be no
distinction between the CLUSTER and OVIRT networks?

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?

Eugène NG

Compatibilty issue
by carl langlois
Hi,
I have upgraded ovirt to 4.3 and now I have some vm that I can start
because of the cluster compatibility version. Those VM where in save state
when I updated the cluster compatibility version. Now they are in a down
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

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:

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.

Impossible to install Windows VMs on 4.4.1
by fgarat＠gmail.com
Hi,
I'm having problem after I upgraded to 4.4.1 with Windows machines.
The installation sees no disk. Even IDE disk doesn't get detected and installation won't move forward no matter what driver i use for the disk.
Any one else having this issue?.

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 :)
