Proxmox 7 on contabo I can only start container . All linux and windows VMs hang on startup

[Meridion SRL]

I bought a new VDS with Proxmox 7 on contabo.com. I already have another one with Proxmox 6 where everything works fine. On the new one with Proxmox 7 I have a problem that I believe is hardware, but I would like confirmation from you, I can create containers but not VMs. All Linux and Windows VMs crash on first boot without even showing me the operating system installation masks

Hi,

are there any related errors/warnings in the syslog (journalctl -p4 -b)?

Also the VMs crash instantly after starting? Could you provide the config (qm config <vmid>) of such a VM?

I'm more and more convinced that it's a hardware problem or in any case of the machine's bios setting, is there any expert who can at least suggest me the tests to do to understand the problem?

Dear, did you find a solution? I have the same problema. Thank you
