Very strange all this. It looks like several files got lost:

# xe pbd-plug uuid=f7bde4ab-7d90-c1d2-eb29-43eba29b9d04
The SR could not be connected because the driver was not recognised.
driver: xfs

This SR was running fine for several month. Now suddenly the driver for it is missing.
Do you maybe know which package I have to reinstall to get this driver?

@olivierlambert We are using XCP-ng 8.2.1.

I think I am now one step further. I uninstalled xapi-core and then reinstalled it. Now at least all the "xe" commands work again.

We did a yum update on our XCP-ng server and then a reboot. Afterwards Xen does not work anymore. On the console I always get this error message:

Failed to log in via xapi's Unix domain socket in 300.000000 seconds

After investigating I found out that the xapi.service file is missing.

systemctl --all
...
xapi.service                      not-found inactive   dead         xapi.service
...

How can I get this file back?

@ckargitest You need to run:

fs0:
cd \efi\boot

and then run the program which is in this folder.

It took me a while as well to figure it out.

Is there a web page with a list of features which are already implemented in XO Lite and with a list of features that are planned next?
