Hello,

we have the problem, that the host is restarting, when we start a server with to much ram. For example, if we have 32GB free ram, and we start a server with 80GB Ram, the host is crashing.

On another host it doesnt crash, we recieve there the following error:

kvm: cannot set up guest memory 'pc.ram': Cannot allocate memory
TASK ERROR: start failed: command [...] '' failed: exit code 1

How can we set our new host up, that we get also this error and no crash?

Host1: Version with that errormessage and no crash: 3.4.-11
Host2: Version with the crash: 3.4-6

Host 1 has 2GB Swap
Host 2 has 64GB Swap

Regards
