6.0.1

Expose VMware Hardware Assisted Virtualization
You can expose full CPU virtualization to the guest operating system so that applications that require
hardware virtualization can run on virtual machines without binary translation or paravirtualization.
Prerequisites
n
Verify that the virtual machine compatibility is ESXi 5.1 and later.
n
Intel Nehalem Generation (Xeon Core i7) or later processors or AMD Opteron Generation 3
(Greyhound) or later processors.
n
Verify that Intel VT-x or AMD-V is enabled in the BIOS so that hardware assisted virtualization is
possible.
n
Required Privileges: Virtual machine.Configuration.Settings set on the vCenter Server system.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
2 On the Virtual Hardware tab, expand CPU, and select Expose hardware-assisted virtualization to
guest OS.
3 Click OK.
The Manage tab refreshes, and the Nested Hypervisor CPU option shows Enabled.
Enable Virtual CPU Performance Counters
You can use performance tuning tools in the guest operating system for software profiling. You can identify
and improve processor performance problems. This capability is useful for software developers who
optimize or debug software that runs in the virtual machine.
The following conditions apply:
n
If virtual CPU performance counters are enabled, you can migrate the virtual machine only to hosts that
have compatible CPU performance counters.
n
If an ESXi host's BIOS uses a performance counter or if Fault Tolerance is enabled, some virtual
performance counters might not be available for the virtual machine to use.
NOTE If a virtual machine resides on an ESXi host in an EVC cluster, CPU counters are not supported for
virtual machine creation or editing. You must disable CPU performance counters.
