Use with the FibreChannelWwpnMinimum parameter to establish a range of WWPNs that the specified Hyper-V host can assign to virtual Fibre Channel adapters. .PARAMETER FibreChannelWwpnMinimum Specifies the minimum value that can be used to generate the World Wide Port Names on the Hyper-V host. Use with the FibreChannelWwpnMaximum parameter to establish a range of WWPNs that the specified Hyper-V host can assign to virtual Fibre Channel adapters. .PARAMETER MacAddressMaximum Specifies the maximum MAC address using a valid hexadecimal value. Use with the MacAddressMinimum parameter to establish a range of MAC addresses that the specified Hyper-V host can assign to virtual machines configured to receive dynamic MAC addresses. .PARAMETER MacAddressMinimum Specifies the minimum MAC address using a valid hexadecimal value. Use with the MacAddressMaximum parameter to establish a range of MAC addresses that the specified Hyper-V host can assign to virtual machines configured to receive dynamic MAC addresses. .PARAMETER MaximumStorageMigrations Specifies the maximum number of storage migrations that can be performed at the same time on the Hyper-V host. .PARAMETER MaximumVirtualMachineMigrations Specifies the maximum number of live migrations that can be performed at the same time on the Hyper-V host. .PARAMETER NumaSpanningEnabled Specifies whether virtual machines on the Hyper-V host can use resources from more than one NUMA node. .PARAMETER ResourceMeteringSaveIntervalMinute Specifies how often the Hyper-V host saves the data that tracks resource usage. The range is a minimum of 60 minutes to a maximum 1440 minutes (24 hours). .PARAMETER UseAnyNetworkForMigration Specifies how networks are selected for incoming live migration traffic. If set to $True, any available network on the host can be used for this traffic. If set to $False, incoming live migration traffic is transmitted only on the networks specified in the MigrationNetworks property of the host. .PARAMETER VirtualHardDiskPath Specifies the default folder to store virtual hard disks on the Hyper-V host. .PARAMETER VirtualMachineMigrationAuthenticationType Specifies the type of authentication to be used for live migrations. The acceptable values for this parameter are 'Kerberos' and 'CredSSP'. .PARAMETER VirtualMachineMigrationPerformanceOption Specifies the performance option to use for live migration.
