VM Processors
A physical core is what it sounds like – an actual physical processor core in your CPU. Each physical core has its own circuitry and its own L1 (and usually L2) cache can read and execute instructions separately (for the most part) from the other physical cores on the chip.
A logical core is more of a programming abstraction than an actual physical entity. A simple definition of a logical core is that it is a processing unit that is capable of executing its own thread in parallel with other logical cores. In fact you could say that a logical core is the same as a thread.
You can have multiple logical cores per physical core. However logical cores share resources with other logical cores operating on the same physical core, so having more logical cores will not necessarily get you the same performance increase as having more physical cores.
Hyper-V VM Integration Services
Hyper-V integration services, are a bundled set of software which, when installed in the virtual machine improves integration between the host server and the virtual machine. Integration services (often called integration components), are services that allow the virtual machine to communicate with the Hyper-V host. Hyper-V Integration Services is a suite of utilities in Microsoft Hyper-V, designed to enhance the performance of a virtual machine’s guest operating system.
