.SYNOPSIS This function is meant to be used in situations where Docker-For-Windows (Docker CE) is being installed on a Windows Guest VM (as opposed to Bare Metal). It gathers a lot of information about the Windows Guest VM, as well as its Hyper-V hypervisor (if appropriate credentials are provided). The function can be run from anywhere as long as it's pointed at a Guest VM (via the -TargetHostNameOrIP or -TargetVM parameters). If you do not have access to the Guest VM's hypervisor or if the hypervisor is not Hyper-V, make sure to use the -TryWithoutHypervisorInfo switch. .DESCRIPTION See .SYNOPSIS .PARAMETER TargetHostNameOrIP This parameter is OPTIONAL. This parameter takes a string that represents the IP Address, DNS-Resolvable HostName, or FQDN of the Guest VM that you would like to gather info from. If it is NOT used (and if the -TargetVMName parameter is not used), the function will assume that the localhost is the Guest VM that you would like to gather information about. .PARAMETER TargetVMName This parameter is MANDATORY (for its parameter set). This parameter takes a string that represents the name of the Hyper-V VM that you would like to gather info from. Using this parameter requires that you use the -HypervisorFQDNOrIP and -HypervisorCreds parameters, unless the localhost IS the Hyper-V hypervisor. .PARAMETER HypervisorFQDNOrIP This parameter is OPTIONAL. This parameter takes a string that represents the IP, DNS-Resolvable HostName, or FQDN of the Hyper-V hypervisor that is managing the Guest VM that you would like to gather info from. If the localhost is NOT the Hyper-V hypervisor and if you are NOT using the -TryWithoutHypervisorInfo switch, then this parameter becomes MANDATORY. .PARAMETER TargetHostNameCreds This parameter is OPTIONAL. This parameter takes a pscredential object that contains credentials with permission to access the Guest VM that you would like to gather info from. If the localhost is the Guest VM target, or if you are logged in as a user that already has access to the Guest VM, then you do NOT need to use this parameter. .PARAMETER HypervisorCreds This parameter is OPTIONAL. This parameter takes a pscredential object that contains credentials with permission to access the Hyper-V hypervisor that is managing the Guest VM that you would like to gather info from. If the localhost IS the Hyper-V hypervisor, or if you are logged in as a user that already has access to the Hyper-V hypervisor, then you do NOT need to use this parameter. .PARAMETER TryWithoutHypervisorInfo This parameter is OPTIONAL. This parameter is a switch. If used, this function will not attempt to gather any information about the hypervisor managing the target Guest VM. Be sure to use this switch if you do not have access to the hypervisor or if the hypervisor is not Hyper-V. .PARAMETER AllowRestarts This parameter is OPTIONAL. This parameter is a switch. By default, this function installs Hyper-V on the target Guest VM is it isn't already. This is part of a test that is used to determine if an External vSwitch attached to a Nested VM on the Guest VM can actually reach an outside network. If Hyper-V has not already been installed on the target Guest VM, then a restart will be required. You can use this switch to allow the Guest VM to restart. The function will remain in a holding pattern until the Guest VM comes back online, so you will NOT need to run this function twice. .PARAMETER NoMacAddressSpoofing This parameter is OPTIONAL. This parameter is a switch. If used, this function will NOT conduct the test to determine if an External vSwitch attached to a Nested VM on the Guest VM can reach an outside network. In other words, the assumption will be that all Nested VMs will be on a Hyper-V Internal network on the Guest VM. HOWEVER, since it is still possible to configure networking such that Nested VMs on an Internal Hyper-V network can reach an outside network, a test will still be conducted to determine if an Internal vSwitch attached to a Nested VM can reach an outside network via NAT. .PARAMETER SkipHyperVInstallCheck This parameter is OPTIONAL. This parameter is a switch. If used, this function will assume that Hyper-V is already installed on the target Guest VM and not attempt any verification or installation. .PARAMETER SkipExternalvSwitchCheck This parameter is OPTIONAL. This parameter is a switch. If used, this function will NOT conduct the test to determine if an External vSwitch attached to a Nested VM on the Guest VM can reach an outside network. In other words, the assumption will be that all Nested VMs will be on a Hyper-V Internal network on the Guest VM. .EXAMPLE # Open an elevated PowerShell Session, import the module, and - PS C:\Users\zeroadmin> Get-GuestVMAndHypervisorInfo #> function Get-GuestVMAndHypervisorInfo { [CmdletBinding(DefaultParameterSetName='Default')] Param( [Parameter( Mandatory = $False, ParameterSetName = 'Default' )] [string]$TargetHostNameOrIP, [Parameter( Mandatory=$True, ParameterSetName = 'UsingVMName' )] [string]$TargetVMName, [Parameter(Mandatory=$False)] [string]$HypervisorFQDNOrIP, [Parameter(Mandatory=$False)] $TargetHostNameCreds, [Parameter(Mandatory=$False)] $HypervisorCreds, [Parameter(Mandatory=$False)] [switch]$TryWithoutHypervisorInfo, [Parameter(Mandatory=$False)] [switch]$AllowRestarts, # -NoMacAddressSpoofing WILL result in creating a Local NAT with an Internal vSwitch on the # Target Machine (assuming it's a Guest VM).
