I have changed number of cpu cores with following command:

VBoxManage modifyvm "Ubuntu_16_04" --cpus 4

When I check with

vboxmanage showvminfo Ubuntu_16_04 --details

I get:

Number of CPUs:  4

But when I login onto guest machine:

cat /proc/cpuinfo

Result is:

cpu cores   : 1

Host and guest machines are ubuntu server 16.04. What could be a problem? Thank you
