Hello everyone,
I have two s740 Futro that I previously ran in a Proxmox cluster with ZFS. But since there were always problems with reboot, I wanted to let the two run as separate nodes.

So now to my problem, previously they ran without any problems. But not anymore after reinstalling pve 7.4 and 8.0.

The BIOS is currently v1.13.0 VT-d is active, 16GB RAM has already been replaced by 4GB as a test, m.2 480GB has been replaced by a 240GB, no other drives are connected.
As a test, I also controlled the server separately with just one client in an isolated network, so to speak.

However, everything comes out the same.

As soon as I start an LXC container or a VM, the web interface loads very slowly or fails, there are connection interruptions via ssh, and access works very slowly.

After starting an empty and new LXC container on Ubuntu 22.04, the load goes up to 1.00 0.95 0.62, the following appears in the log under Proxmox.

The really strange thing is that I have two s740s and the same problem occurs on both.
