Re: Error during deployment of ovirt-engine
by Peter H
Hi Jonas,
I get the same error when I try to install. Last weekend I managed to do it
(but with a lot of other problems) so something has changed during the week.
After the VM is up I logged in through ssh and saw that the oVirt appliance
comes with Python-3.6 and Python-3.8 which both have netaddr installed.
Part of the log:
...
[ INFO ] TASK [ovirt.ovirt.engine_setup : Update setup packages]
[ INFO ] skipping: [localhost]
[ INFO ] TASK [ovirt.ovirt.engine_setup : Copy yum configuration file]
[ INFO ] changed: [localhost -> 192.168.222.35]
[ INFO ] TASK [ovirt.ovirt.engine_setup : Set 'best' to false]
[ INFO ] changed: [localhost -> 192.168.222.35]
[ INFO ] TASK [ovirt.ovirt.engine_setup : Update all packages]
[ INFO ] changed: [localhost -> 192.168.222.35]
[ INFO ] TASK [ovirt.ovirt.engine_setup : Remove temporary yum
configuration file]
[ INFO ] changed: [localhost -> 192.168.222.35]
[ INFO ] TASK [ovirt.ovirt.engine_setup : Set offline parameter if
variable is set]
...
I noticed that after the task "Update all packages" Python-3.9 gets
installed and that version does not have netaddr installed. My theory is
that the playbook somehow uses the newest version of Python which is
installed.
pip3.9 list
Package Version
------------ -------
ansible-core 2.13.3
cffi 1.14.3
cryptography 3.3.1
idna 2.10
pip 20.2.4
ply 3.11
pycparser 2.20
PyYAML 5.4.1
setuptools 50.3.2
six 1.15.0
I have tried another run where I installed the netaddr module as soon as
Python-3.9 got installed and that installation went further but then it had
another error.
When I log into my hosted engine VM from last week there is no Python-3.9.
My dnf(1) skills are not good enough to figure out which dependency is
causing Python-3.9 to be installed.
There are probably a lot of other modules missing that can explain the
other error(s) I see.
I will see if I can find out how to file a proper bug report.

Re: Should I migrate existing oVirt Engine, or deploy new?
by David White
Hi Paul,
Thanks for the response.
I think you're suggesting that I take a hybrid approach, and do a restore of the current Engine onto the new VM. I hadn't thought about this option.
Essentially what I was considering was either:
- Export to OVA or something
OR
- Build a completely new oVirt engine with a completely new domain, etc... and try to live migrate the VMs from the old engine to the new engine.
Do I understand you correctly that you're suggesting I install the OS onto a new VM, and try to do a restore of the oVirt settings onto the new VM (after I put the cluster into Global maintenance mode and shutdown the old oVirt)?

Or would it be better for me to install a completely new Engine, and then somehow migrate all of the VMs from the old engine into the new engine?

Migrating VM from old ovirt to a new one
by Facundo Badaracco
Hi everyone
I would like to ask you a question
I have an ovirt 4.4 which got corrupted certs and I can't access the gui.
It gives me error 500 internal when I want to access.
I have a new ovirt 4.5 on glusterfs which I would like to migrate all my
vm's to.
Is this possible? Can it be done by cli? It would save me from having to
reinstall all the vm's.

Gluster setup for oVirt
by Jonas
Hello all
I tried to setup Gluster volumes in cockpit using the wizard. Based on
Red Hat's recommendations I wanted to put the Volume for the oVirt
Engine on a thick provisioned logical volume [1] and therefore removed
the line thinpoolname and corresponding configuration from the yml file
(see below). Unfortunately, this approach was not successful. My
solution is now to only create a data volume and manually create a thick
provisioned gluster volume manually. What would you recommend doing?
Thanks your any input :)
Regards,
Jonas

static IP with OVN subnet
by ravi k
Hello,
Hope you are all doing well. We have an interesting thing going on and so wanted to share with you all for some ideas and feedback.
We configured a cluster with OVS switch and added an external network with subnet. So OVN started managing the subnet using DHCP. But here's the problem. When we add a nic with this network, an ip is assigned by DHCP. But we want an IP of our choice to be assigned. Here's what we tried.
1. We tried using the ovn-nbctl lsp-set-address like ovn-nbctl lsp-set-addresses 7840c97b-73c2-4246-a2a8-0e9e5b7f420a "56:6f:6b:54:00:ec 10.19.3.8" to update the static IP. But this does not persist a NIC unplug or a VM reboot.
So you might ask why not just try assigning a static IP and not add the external subnet. We want to use security groups. For security groups to work, the ip assigned to the NIC and the IP in the value for fixed_ips in `openstack port show` should be the same. So the same thing repeats here as well. If we use the `openstack port set` to update the fixed_ips, a NIC unplug or a VM reboot will remove the IP.
We have an internal IPAM that provides us IPs during our automated provisioning. Did anyone try this or have any ideas how to work around this? The only option seems to be just use DHCP and then update that IP in our internal IPAM tool.
Please let me know if I'm unclear and any more info is required.
Regards,
rav

Resize hosted-engine disk
by Jorge Visentini
Hi all.
Is it possible to resize the disk of the HostedEngine VM?
I resized the LUN on Storage, but I can't resize the disk/LVM.
How is it possible to resize the disk?
All the best!
