Hi Nir,

Tried to do this but somehow the UI does not let me drag the network anywhere in the window.

Just in case I tried with both the host in maintenance mode and not in maintenance mode. Tried drag and drop on any area of the dialog box I could think off without success

Tried with 3 different browsers to rule out browser incompatibility
- Safari
- Chrome
- Firefox


So NO idea why no network interfaces are detected on this node. FYI my CPU model is a Broadwell one.

If engine does not detect any network interface "setup networks" is
not going to be
very useful.

I'm not sure how you got into this situation, maybe this is an upgrade issue.

I suggest to start clean:

1. Remove current vdsm install on the host

dnf remove vdsm\*

2. Upgrade you host to latest CentOS Stream 8

3. Add the ovirt repos:
https://copr.fedorainfracloud.org/coprs/ovirt/ovirt-master-snapshot/

dnf copr enable -y ovirt/ovirt-master-snapshot centos-stream-8
dnf install -y ovirt-release-master

4. Make sure your host network configuration is right

You should be able to connect from your engine machine to the host.

5. Add the host to your engine

Engine will install the host and reboot it. The host should be up when
this is done.

6. Add some storage so you have a master storage domain.

The easier way is to add NFS storage domain but you can use also iSCSI
or FC if you like.

At this point you should have working setup.

The next step is to update engine and vdsm with the Benny patches,
but don't try this before you have a working system.

If you need more help we can chat in #ovirt on oftc.net.

Nir

Best regards
JC
Initial window sees no network interface
Clicking on setup network does not have any interface to which I can assign the ovirtmgmt network

Hi Benny et all,

...

With 4.5 I can not bring the host up

Here is my cluster spec
In the UI I see the following when trying to add host client2


In the screenshot we see 2 issues:
- host does not default route
- host cpu missing some features

To resolve the default route issue, click on the host name in the
"Hosts" page, then
click on the "Network interfaces", and then "Setup networks" button,
and make sure
the ovirtmgmt network is assigned to the right network interface, and
edit it as needed.


Adding screenshot in case it was not clear enough.


To quickly avoid this issue, select an older cpu from the list. This
should be good
enough for development. Maybe Arik can help with using the actual CPU you have.

However when I check the nodes capabilities using Vdsm client I get this for each flag mentioned

So all the flags the UI claims as missing are actually present.
