Strange. Try starting the VM using the console (right click on VM and choose "Console" from the menu, then hit Start from the button on the top right of the console window). Can you see anything happening there?
Also, can you post the VM's config? Log in to the host machine over SSH and see the contents of /etc/pve/nodes/<hostname>/qemu-server/<id>.conf
I tried to and no respons. But, this mornng i first hit the start button for the vm and then hit console and i get this error new error :
