Hi,
I am struggling to get an oVirt cluster setup (for a PoC with some workstations) for the
past more than one week and am getting nowhere. Following is my environment:
Machine: Dell Workstation with i7, 16G RAM, 256G (I have got couple of more of this
machine but could not getr beyond the first one)
OS: oVirt minimal
(https://resources.ovirt.org/pub/ovirt-4.5/iso/ovirt-node-ng-installer/4.5...)
Documentation followed:
https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng...
Cluster name chosen: my.cluster
First node host name: node1-ovirt.my.cluster
Engine VM name: ovirt-engine.my.cluster
The documentation states that there should be resolvable DNS entries for both the oVirt
hosts *as well as* for the oVirt engine VM. I am a bit confused on this as the VM will get
a DHCP address only after running the 'hosted-engine' script. What ip address
should I have for the engine VM (say if I have my engine host name as
ovirt-engine.my.cluster)? If I have no entry for the engine in the DNS I get the following
error:
[ ERROR ] Host name is not valid: ovirt-engine.my.cluster did not resolve into an IP
address
Please provide the FQDN you would like to use for the engine.
Note: This will be the FQDN of the engine VM you are now going to launch,
it should not point to the base host or to any other existing machine.
Engine VM FQDN:
So I simply added an entry for 'ovirt-engine.my.cluster' with a dummy value
192.168.0.222 (this is an ip address on the host subnet; but the engine gets a DHCP
address from a different subnet from a virtual network from the host; I dont understand
this) which moves away from the above problem and goes all the way (after providing the
values for a few other questions) to hang at
'Wait for the host to be up'
for a while and eventually fail with an error message:
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg":
"Host is not up, please check logs, perhaps also on the engine machine"}
At this point a vm is running in the host. I logged on to the VM and searched the logs and
found the following line in the /var/log/ovirt-engine/engine.log:
ERROR [org.ovirt.engine.core.common.utils.ansible.AnsibleExecutor]

and in the file

I found the following error:
"msg" : "The conditional check 'cluster_switch == \"ovs\" or
(ovn_central is defined and ovn_central | ipaddr)' failed. The error was: The ipaddr
filter requires python's netaddr be installed on the ansible controller\n\nThe error
appears to be in

line 3, column 5, but may\nbe elsewhere in the file depending on the exact syntax
problem.\n\nThe offending line appears to be:\n\n- block:\n - name: Install ovs\n ^

At the moment I ran out of ideas. Am I not following something in the document correctly?
Please let me know if you need more information in this regard
Thanks
