Hi,

I have upgraded from Proxmox VE 4.3 to 4.4. via CD iso. After upgrade I have noticed that one VM which is ubuntu 16.04 LTS caused log printouts on host machine every time when it boots.

Hi,

this is harmless you can ignore it.
If you do not like this massage change the VM's CPU type from "host" to your current host physical CPU.
