function Get-VMSpeculativeExecution { <# .SYNOPSIS Get VM compliance on VMSA-2018-0004 Security Advisory .DESCRIPTION Will validate VM for Spectre/Hypervisor-Assisted Guest Mitigation https://www.vmware.com/security/advisories/VMSA-2018-0004.html https://www.vmware.com/security/advisories/VMSA-2018-0012.1.html .NOTES File Name : Get-VMSpeculativeExecution.ps1 Author : Edgar Sanchez - @edmsanchez13 Contributor : Ariel Sanchez - @arielsanchezmor Version : 2.4.4 .Link https://github.com/arielsanchezmora/vDocumentation .PARAMETER VM Specifies the virtual machine(s) which you want to validate compliance on. .EXAMPLE C:\PS> Get-VM -Server $VCServer | Get-VMSpeculativeExecution Retrieves the compliance status on Spectre of all virtual machines which run in the $VCServer vCenter Server. .EXAMPLE C:\PS> Get-VM -Name "labvm001" | Get-VMSpeculativeExecution Name : labvm001 Power state : PoweredOn VM Guest OS : Microsoft Windows Server 2008 (32-bit) ESXi Host : aluvm014.emea.convergys.com Cluster EVC mode : Disabled Hardware version : v13 ESXi MCU CPUID : IBPB,IBRS,SSBD,STIBP ESXi PCID/INVPCID : True VM MCU CPUID : STIBP,SSBD,IBRS,IBPB VM PCID/INVPCID : PCID,INVPCID Last PoweredOn : 7/31/2018 5:36:47 AM Hypervisor-Assisted Guest mitigation : Supported/Enabled PCID optimization : Supported/Enabled .EXAMPLE C:\PS> Get-VM -Location "MyClusterName" | Get-VMSpeculativeExecution Retrieves the compliance status on Spectre of all virtual machines which run in the "MyClusterName" cluster. .EXAMPLE C:\PS> Get-VMHost "MyESXiHostName" | Get-VM | Get-VMSpeculativeExecution Retrieves the compliance status on Spectre of all virtual machines which run on the "MyESXiHostName" ESXi host. .EXAMPLE C:\PS> Get-VMHost "MyESXiHostName" | Get-VM | Get-VMSpeculativeExecution | Export-Excel "VMValidation.xlsx" -WorkSheetname "VMresults" Retrieves the compliance status on Spectre of all virtual machines which run on the "MyESXiHostName" ESXi host and exports to Excel .NOTES This advanced function assumes that you are connected to at least one vCenter Server system. #> <#
