Now it has also RPM persistence designed as a mechanism by which packages
installed through yum/dnf can be saved and automatically re-applied when
the OS is updated.

And also the different guides on how to install them.

Re: [ovirt-users] Q: oVirt Node Update Wiped my Updates

[Johan Bernhardsson]

ovirt node is a small minimal os and will wipe your manually installed
packages on an upgrade.

If you want local packages that are critical for you you should install
full centos/rhev server and use that as a virtualization node. (This is
what i did since i wanted more control of the virtulization nodes)

[ovirt-users] Q: oVirt Node Update Wiped my Updates

[Andrei V]

Hi !

I have updated today oVirt node 4.1 via yum, installed from oVirt DVD.
Update was a minor version change.
Now all software I had installed, including mc, Samba, etc. have been
lost. Looks like oVirt node is being updated with whole system 600MB
image, not just with rpms (please correct if I'm wrong here).

Keeping my manually installed software is crucial, since it has UPS and
hardware RAID monitor.

Can anyone suggest if this is normal behavior or a single glitch ?

So far I found only this instruction for node installation:
https://www.ovirt.org/documentation/install-guide/chap-oVirt_Nodes/

And it uses pre-made DVD ISO, not manual install with RHEL/CentOS DVD
and RPMs from yum repository.

Thanks in advance for any suggestion(s).
Andrei

Hello all,

That document mainly refers to vintage node.
In Next Generation Node now we have rpm persistence; please check
https://www.ovirt.org/develop/release-management/features/node/node-next-persistence/





I'm sure glad we tested!

On one Node image we had images locally stored in /exports and shared 
out via NFS. After an upgrade & reboot, images are gone.


If we "Convert to local storage" will the data persist?  I am planning 
to test, but want to be sure how this is designed.


I assume during a Gluster installation something is also updated in 
oVirt Node to allow for the Gluster partition to persist?


At this point I'm thinking I should manually install via CentOS7 to 
ensure folders and partitions are persistent. Is there any downside to 
installing over CentOS7?

 Ciao Matteo,

 No need to do custom configuration to expose your VMs.

 Are you trying on bare metal or on VMs with the engine VM as a nested

Get netdata to query libvirt for the IO parameters directly. It should be
configured with authentication against libvirt (the same password VDSM
uses).

Hi,

would it be possible for future releases to add an option to the add new host 
tab to put the host in maintenance after installation instead of activating it.
The same would be for reinstall.

I have the problem now, that all hosts after installation will be activated, 
but network is not configured yet. Therefore host will be in non operational

Hi Luca,

In my case (bond-vlans-bridges), the problem turned out to be missing
interface parameter:
- name: setup host networks:
  ovirt_host_networks:
interface: bond0   # I missed this one
bond:
  name: bond0
  interfaces
  - slave1
  - slave2
networks:
- name: rhevm# untagged, vm_network: no
  boot_protocol: dhcp
- name: vms  # vlan_tag: TAG, vm_network: yes
  boot_protocol: none

If the ansible + ovirt network setup doesn't work for for you (it did
for me), I'd suggest to move the interfaces configuration to a separate
playbook that you have to keep anyway for repositories, NTP or engine
ssh key.

 Hi everyone, my name’s Matteo and I’m a new oVirt user.

 I’m trying to install the gluster hyperconverged solution in a lab
 environment following the How-To wrote by Jason Brooks:

 https://ovirt.org/blog/2017/04/up-and-running-with-ovirt-4.1
 -and-gluster-storage/

 Sadly, I cannot understand how to configure the network on the
 self-hosted engine and I’m unable to make it available from outside the
 host.

 As written in the HowTo I created three hosts (ovirt-note 4.1.7) each
 one with two nics, one for gluster and one for management, the network is a
 static LAN with FQDN resolvable (also reverse) by a local DNS. Here the
 details:

 Gateway: 172.16.1.1

 DNS: 172.16.1.12

 Host1: 172.16.1.210 (management) – 172.16.2.210 (gluster)

 Host2: 172.16.1.220 (management) – 172.16.2.220 (gluster)

 Host3: 172.16.1.230 (management) – 172.16.2.230 (gluster)

 Engine: 172.16.1.200

 When installing the engine I choose to brigde the management’s nic
 (172.16.1.210) of host1 but, once the installation is completed, I'm unable
 to reach the engine from the LAN where the hosts are connected. The engine
 (172.16.1.200) can ping only host1 (172.16.1.210) and only host1 can ping
 the engine.

 As far as my network knowledge goes, to make the engine available from
 the outside of host1 I would need to use a third nic or to use some device
 to associate the ip and MAC address of the engine’s nic.

Thank you for the explanation, I'm going to try it in the evening. I'll
keep you posted.

 Anyone could help me to solve this issue?

OK, your issue is caused by vdsm-no-mac-spoofing filter on your L1 VMs.
Please create a custom vNic profile on your external oVirt engine setting
the "network filter" field to "no network filter".
Now you can edit your ovirt-node VMs setting the network profile of the
nics you are going to use for the management bridge to the profile with "no
network filter".
You have to shutdown and restart your ovirt-node VMs and then you could
retry the deployment.

Ciao Simone,

thank you for your answer.

My lab is a nested environmet. I installed ovirt on bare metal with the
engine on another machine. On this setup i have 6 VMs:

- 172.16.1.1  pfSense as firewall/gateway
- 172.16.1.10  a windows 2016 used as network guest
- 172.16.1.12  a nethserver installation as DNS server ( also on
172.16.2.12 )
- the three ovirt-nodes as i described on my e-mail

All the machines are pingable, only the engine inside host 1 is unreachable
and can ping only host1.


Cheers

Matteo
