Where did you install Debian 9 onto?
I rephrase my question, did you install debian 9 on a physical machine or inside a virtual machine?
Do you see any error/warning messages in Proxmox under /var/log/syslog or in journalctl -xb, when you reset a VM?

A reboot of the VM works without issues? When you reset the VM then it should show task entries like this.

It doesn't look like, I could reproduce your issue, nor finding the reason.
I only have two other suggestions in my head:
- try a different VM
- do a new installation of PVE
correct, KSM has nothing to do with the issue, I just assumed from his description that the installation might be bust.that said, KSM missing would NEVER be the issue for a VM failing to RESTART
Good point, but then you would see some log entries. Still worth to investigate further on this matter, in my opinion.As for your reboot issues, when you try to reboot or reset a VM, does your cpu, ram, disk access, or IO Delay, max out or go beyond max?
if your bottle-necking on any of those, it can easily cause the VM to time out, and KVM/Proxmox to give up on it.

You did state you had 100s of VMs on each node.
if CPU or IO delay is the issue, then you will want to uninstall KSM again, it greatly adds to CPU usage.
if your CPU usage is fine, then KSM will help you in saving RAM both for virtual machines, and other processes on the node.
@mada would it still be possible to do a installation directly from Proxmox ISO?Could you do a test installation with the Proxmox ISO, to check if the problem then still exists?

At the moment, we only know that there is a difference, not that something would be broken, that would need fixing.did this will ever fixed ?
Are your installations according to the instructions on our wiki?

Proxmox is on top of Debian even when you install from ISO, you can install all the packages from Debian. Which extra stuff do you need?

If you may post, what customization you did on a Debian installation. Then we could follow it a little deeper into the rabbit hole.
