The host has 16GB but can be expanded.

Well your bottleneck is going to be memory at present<br />
<br />
Can you see that ?<br />
<br />
If you have three VMs all allocated 4GB and some left for host

I totally understand the RAM side it the VCPU that I am not understanding.

did you read the articles ?

I have an EE article that has a good explanation of the relationship between virtual CPUs and the physical CPU pipeline: <a href="https://www.experts-exchange.com/articles/13256/Some-Hyper-V-Hardware-and-Software-Best-Practices.html" rel="ugc">Some Hyper-V Hardware and Software Best Practices</a>.<br />

Still trying to get my head around this, I know that might seem lame but I am struggling. If I have Xeon E5-2620 V3 6-CORE how many VCPU would I have?

Dear All <br />

Please, can someone assist me? I am trying to wrap my head around how many VM machine I could run on the below CPU, I don't know how you calculate this and it's starting to annoy me somewhat that I don't understand.<br />

Hyper-V

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.
