failed: command '/usr/bin/kvm -id 102 -name HrmTServer

Hi,

VM-102 suddenly shut down and failed to start.
Constantly following error appeared.
Why do you think it's closed?
I could not understand why the device suddenly shut down.

vm: cannot set up guest memory 'pc.ram': Cannot allocate memory

Hardware picture

Looks like you don't have enough RAM available for the VM to start.

 

[mehmethanifi]

you will see two pictures. One of them is the amount of ram of PVE.
The other one is the ram quantity of VM 102.
It's impossible for Ram to be inadequate.
What do you think caused the error to occur?
