Questions tagged [vmware-esxi]

VMWare ESXi is an installable/embeddable virtualization platform based around the ESXi Hypervisor.

VMWare ESXi is a type 1 hypervisor based virtualization platform that installs on bare hardware (no host OS required) that allows running multiple guest virtual machines simultaneously.

ESXi is available freely with basic single-server functionality, but more advanced functionality requires licensing commercial versions of VMWare vSphere (formerly known as VMWare Infrastructure prior to version 4.0). ESXi lacks the linux-based service console included with VMWare ESX, further reducing install footprint and attack surface.

In VMware ESXi 5.x, does it make a difference if I select 2 CPU cores vs. 2 CPU sockets?

Title pretty much says it all. I'm just wondering if this makes a difference in the way VMs will process things and if one method is preferable vs. another.
