Hello,

Looks like you are checking this directory in the engine. You will get this in the host. 
Also check vdsm service is running or not using systemctl status vdsmd

Hello Ritesh

I can see the NIC attached to the host in the UI.
However, I don’t have a directory /var/log/vdsm.
I am sharing the filetree of my /var/log in the separately attached text file:

Thanks, Toni

Hello,

Can you share vdsm logs you can find at /var/log/vdsm/vdsm.log.

I guess this might be a vdsm issue between an engine and host.
also check in ui whether a nic is attached to the host after upgrade.

 Hi

I am looking for help after my oVirt upgrade failed.


I have upgraded from ovirt 4.3 to 4.4 following the instructions here:


It's a single-host (standalone engine) test environment.
I wiped CentOS 7 and reinstalled a fresh CentOS 8.
I installed the oVirt 4.4 repo and all the necessary software packets.

I used `engine-backup --mode=restore --file=/tmp/ovirt-engine-pre-upgrade.backup --provision-all-databases` from a backup file I created before I started the upgrade.
After the restore, I ran `engine-setup`.

I did not get any errors during any of these steps on the console.
So the upgrade could be considered successful from that perspective.

After the upgrade, I login to the ovirt admin portal, and I try to "Activate" my host (was set to "Maintenance" mode before upgrade).
The Activation fails with error "NonResponsive" in the GUI.
Under the "bell" icon, I find the Event "Host nuc1.feric.ch is non responsive.”

In /var/log/ovirt-engine/engine.log, I find the following error:
```
2020-11-09 23:12:21,080+01 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-47) [] Command 'GetCapabilitiesAsyncVDSCommand(HostName = nuc1.feric.ch, VdsIdAndVdsVDSCommandParametersBase:{hostId='d7c30cc0-ac59-4cf3-a1e7-b9fae9db83fb', vds=‘Host[nuc1.feric.h,d7c30cc0-ac59-4cf3-a1e7-b9fae9db83fb]'})' execution failed: java.net.ConnectException: Connection refused
```

`systemctl status ovirt-engine` shows that the engine is running.
I am able to reboot the host from the oVirt GUI directly.

Does anyone have an idea how to proceed?

Many thanks
Toni
