You do understand that the critical bit there (though it affects the user bus, does that still work for you?) is unsetting XDG_RUNTIME_DIR ?

You re-executed the user bus, not the system one. And you're using sudo, so you'll have to make sure that environment isn't compromised (try a root shell)
Can you btw. still access the session bus?

systemctl --user status dbus

So the session bus is gone and the (recently re/started system bus) looks weird.

kvm guest are running, so i donnot want reboot server

How much of a problem would the reboot be in comparism to the defunct status quo?

I didn't plan it before, and a lot of data was directly placed in the img/qcow 2 corresponding to the virtual machine
I'm afraid that after rebooting, the machine won't be able to start at all (currently it's basically broken, unable to connect to SSH, connected to the physical monitor full screen CPU/RCU error, Ctrl+ALT+F2-F7 doesn't respond).

What I'm controlling is the SSH window that I've been logging in to yesterday

Reinstalling the system and starting these virtual machines may take some time, and they are not configured as "completely identical" virtual machines. Each restart may encounter different problems, so I hope to try to fix the system as much as possible“

So "systemd --system" is gone? You have no init process?

ps -p1

If you've lost PID1, you'll have to reboot.

The installation (packages, kernel, initramfs) looks ok, also

I do not exepect the reboot to fail (kernel/update regressions aside)

You didn't update in 6 months?
systemctl immediately fails, this wasn't caused by an alpm hook during the update.

The journal is 122MB, you're under constant RAM pressure - maybe add some swap… also your sshd is under permanent attack… from within the LAN. Since the journals inception.

The systemd problems indeed start w/ the posted segment, ie. the daemons re-execution.
Do you rely on nfs as system partition (or is this just an outfall of networkd/resolved no longer responding)?

If you've lost PID1, you'll have to reboot.

You didn't update in 6 months?
systemctl immediately fails, this wasn't caused by an alpm hook during the update.

Thank you very much for your reply and help.

It's true that I haven't updated for six months. My main machine is Debian, which has brought me some bad habits.

My total memory is 128G, so the issue of large logs is not that serious.

NFS is mainly used for storing some data. I just deployed it based on FreeBSD recently. Originally, I planned to migrate the data on Arch to it recently, but then I encountered this problem.

After I back up the remaining data, I will reboot this machine.

PID1 is still running?
Why was that not in the output in #15

ps aux -p1

It's listed as idle kernel thread, so probably hangs somewhere in the re-execution and therefore doesn't respond.
No idea whether that could be because it was invoked via the symlink (the reason it didn't show up previously) or rather caused because the system is under memory pressure, but idk whether or how this is salvageable w/o a reboot. Sorry.
