The homepage welcome-screen on a 8.1.0 server point to download of XCP-ng Center 8.0.1.26.
That xcp-ng-center version cannot connect to a 8.1 server.

Is OpenWRT's wan assigned to xcp-ng's NIC1/Lan ?

Do you have more than 2 physical NIC's or is OpenWRT's lan assigned to NIC0?

The tree-view in Center is far better than any overview I can find in XO.
Starting, stopping, restarting a VM is fast and natural to do in that tree view.

That makes Center useful for occasional users, that have to find a way to solve a problem, where XO is targetted at the pro user, who knows how to solve his problem before he starts.
Just to join a new server I get confused every time, and end at a place, where I have to enter its password permanently, which seems wrong.

With Windows on the workstation you have the chicken/egg problem. I run XOce in Virtualbox on my laptop. Not simple compared to Center.

XO is not cheap, and if that forces you into XOce there is confusion between the 3 versions XO, XOA and XOce, dubbed up with different ways to install XOce.

XOlite embedded in the Xcp-ng-host might change things.

So is your question about how to create a SR and how to destroy one? What about @Biggen's link shared above?

The link is not telling, how to change the Local Storage.
As far as I can see, Local Storage is not a partition like SR's on other physical disks.

I'm not sure that your test for the file type is valid.

You are right. Running your test on my server gives same answer
Linux rev 1.0 ext4 filesystem data

Fresh install of RC1 on a test-machine.
Not part of a pool and no SAN. Just local storage on same nvme-ssd, XCP-ng is installed on.
I choose EXT in the install-process.
After install
file -sL /dev/nvme*
says, that the storage is ext3.

Is EXT4 a possibility on Local Storage, or what is the right choise for Local Storage?
