Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Ignoring the model name, it appears this cloud server has 4 single core processors without hyperthreading.

However the model name indicates that it's quad core. I'm not the system admin so I didn't buy this instance of a cloud server, nor have I been configuring it. Doesn't this look a little off though?

The physical CPU is a quad-core processor. The virtual CPU is four single-core processors. The physical and virtual CPU layouts do not have to be identical.

This is normal for vCPUs. Nothing to worry about.

Does vCPU mean virtual CPU? Is it 4 single core CPUs with no hyperthreading or is it a quad core? Why is it normal for a vCPU to have the specs be different than what the manufacturer's specs? –  user784637 Oct 30 '11 at 1:53
    
@LedZeppelin I think that you need to read about how virtual CPUs work in virtual environments. Also, if you gave the downvote, I think it's mildly inappropriate. –  MDMarra Oct 30 '11 at 2:04
    
I didn't give a downvote... –  user784637 Oct 30 '11 at 2:17
    
@LedZeppelin Ok. No prob, it just happened at the same time that you added your comment. :) –  MDMarra Oct 30 '11 at 2:38
