I'm using the vSphere client. When I create a new Virtual Machine I have a selection drop-down to choose the OS version. Except 32bit and 64bit version which I understand (because it's hardware related), I am wondering what difference does it make for VMware if I choose a specific version rather than another.


What difference does VMware if I choose RedHat 5 or RedHat 6? Does hardware look different? Is it just for information purpose? Why vmWare even has to know what operating system the guests are running on?

VMWare chooses sane defaults for what abstracted hardware it presents to the OS.

It chooses those hardware abstractions that have good drivers available in the OS you selected.

Sounds reasonable. – SamK Sep 28 '11 at 12:16
