oVirt 4.4 and management network requirements
by Gianluca Cecchi
Hello,
does oVirt 4.4. support management network distributed between routed
networks and not bound to a single one?
In some environments I see situations where there are 2 different server
farms with networks not necessarily mapped to the same ranges and so it
could be useful to let oVirt hosts of the same cluster to be able to
communicate but not on the same physical network.
Eg vSphere can do it.
Thanks in advance,
Gianluca

Didn't test this, but you can try:
1. Keep a backup of /etc somewhere, just in case.
2. Stop ovirt-websocket-proxy.service
3. Edit /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf , remove
the line with: OVESETUP_CONFIG/websocketProxyConfig
4. Remove:
/etc/ovirt-engine/ovirt-websocket-proxy.conf.d/10-setup.conf
/etc/pki/ovirt-engine/requests/websocket-proxy.req
/etc/pki/ovirt-engine/keys/websocket-proxy.key.nopass
/etc/pki/ovirt-engine/keys/websocket-proxy.p12
/etc/pki/ovirt-engine/certs/websocket-proxy.cer
5. Run engine-setup (perhaps with '--offline', if you want to prevent it
from checking for updates)
Good luck and best regards,

Reconfigure Websocket Proxy
by Anton Louw
Hi Everybody,
I tried looking around, but I am stuck. I am trying to reconfigure my Websocket proxy in order to use noVNC. This is after the Hosted Engine name was changed and also after a new SSL cert was added to the Hosted Engine.
Most of the articles say that I should run “engine-cleanup”, but after learning the hard way, I would rather not do that again 😊 Any other way anybody knows of? I want to completely remove it and then reinstall it.
Thanks

Terraform - Ovirt - seting or get some parameters
by Michal Obeslo
Hi all, we need a help,
we have problem to set and get IP Address when we created virtual machine
when we use terraform.
step by step: what we created
1) we created virtual machine Debian 9
- installed the software ovirt-guest-agent) [systemctl status ovirt-guest
agent = OK
- we created private and public key to connectivity from another computer
by .ssh ) /Jenkins Slave/
2) we created template from virtual machine Debian 9
- set this parameter in template initial Run > user, set static IP in Ovirt
Managemet
3) downloaded project from GitHub - create virtual machine from template
- terraform main file = OK ?
- terraform init = OK
- terraform apply = OK
: yes
create new virtual machine = OK
start automatically virtual machine = OK
- when I check IP Address > IP address not set
- when I check settings in Ovirt management > network > NOT SET
- virtual machine not has IP addres > not working
- when I change settings in Ovirt management in template Debian from Static
IP dhcp > to DHCP
- when I check settings in Ovirt management > network >
IP in Ovit have DHCP, Virtual machine have dhcp OK
But wee need set static IP to Virtual machine and get this IP from
terraform.
Thank you all.
Best regard Michal

How to change IP range of node and hosted engine without break anything ?
by Stéphane Paillet
Hello,
I installed an ovirt node and its hosted engine in a lab. After several
difficulties to install the engine (I don't know why, I didn't have any
problem in the past), I would like to change IPs of both to put them on
another vlan.
How can I do that without break anything ? My main fear is that the data
domain used by the hosted engine use the IP of the node rather than its
FQDN. I change other data domains paths, but don't find how to change
this one, 'cause I can't modify it, and I can't detach / delete it to
recreate another one. I didn't find how to move the engine on another
data domain using the node's FQDN in its path. For now, I don't use DNS,
I just updated /etc/hosts defs on both servers.
If someone could help me, telling me step by step how to change IPs on
each element in good order, I would be grateful.
Thank you.
Cheers,
Stephane

ovirt node 4.4 and infiniband
by Giulio Casella
Hi all,
I have in production a 4.3.9 setup of ovirt, based on a standalone
engine, not HE.
I have 3 datacenters (an 3 clusters). One of these clusters is composed
of many tenth of HP blades, accessing storage via InfiniBand (used as
normal NICs, via ipoib). They're not the state of the art, but I cannot
renew the entire hardware.
After a setup of ovirt node 4.4 I cannot see ib0 nic.
I managed to see it installing CentOS 8, enabling Mellanox repo
(https://linux.mellanox.com/public/repo/mlnx_ofed/latest/rhel8.1/mellanox_...)
and installing package "mlnx-ofed-basic".
In Ovirt Node it's not possible, that package require dependencies from
CentOS 8 repos, not present in ovirt repo.
Is there any chances to have infiniband NICs working in ovirt?
TIA,
