Verify that all .vmdk les are available to the ESXi host on a VMFS3, VMFS5, or NFS datastore.
n
Verify that the virtual machine is stored on VMFS3, VMFS5 or NFS datastores.
n
Verify that the compatibility seings for the virtual machines are not set to the latest supported version.

Determine the ESXi versions that you want the virtual machines to be compatible with. See vSphere
Virtual Machine Administration.
Procedure
1 Click Virtual Machines in the VMware Host Client inventory.
2 Right-click a virtual machine from the list and select Upgrade VM Compatibility from the pop-up
menu.
3 Select the latest supported version and click Upgrade.
Virtual CPU Configuration
You can add, change, or congure CPU resources to improve virtual machine performance. You can set most
of the CPU parameters when you create virtual machines or after the guest operating system is installed.
Some actions require that you power o the virtual machine before you change the seings.
VMware uses the following terminology. Understanding these terms can help you plan your strategy for
CPU resource allocation.
CPU
The CPU or processor is the component of a computer system that performs
the tasks required for computer programs to run, and is the primary element
that performs the computer functions. CPUs contain cores.
CPU Socket
A CPU socket is a physical connector on a computer motherboard that
connects to a single physical CPU. Some motherboards have multiple sockets
and can connect multiple multicore processors (CPUs).
Core
A core contains a unit containing an L1 cache and functional units needed to
run programs. Cores can independently run programs or threads. One or
more cores can exist on a single CPU.
Corelet
An AMD processor corelet is architecturally equivalent to a logical processor.
Certain future AMD processors contain a number of compute units, each of
which has a number of corelets. Unlike a traditional processor core, a corelet
lacks a complete set of private, dedicated execution resources and shares
some execution resources with other corelets such as an L1 instruction cache
or a oating-point execution unit. AMD refers to corelets as cores, but
because these are unlike traditional cores, are referred to as corelets in
VMware documentation to make resource sharing more apparent.
Thread
Some cores can run independent streams of instructions simultaneously. In
existing implementations, cores can run one or two software threads at one
time by multiplexing the functional units of the core between the software
threads, as necessary. Such cores are called dual or multithreaded.
Resource sharing
Shares specify the relative priority or importance of a virtual machine or
resource pool. If a virtual machine has twice as many shares of a resource as
another virtual machine, it is entitled to consume twice as much of that
resource when the two virtual machines are competing for resources.
