To check if your Mac supports VT-X, issue the following command: % sysctl -a | grep
#How to enable virtualization on mac pro#
I've checked a 2012 iMac, a 2017 MacBook Pro and a 2014 Mac mini and all had VT-x supported and enabled.

This includes any software that requires hardware virtualization extensions.It's not mentioned which MacBook Pro is being used, but it's a safe bet that the CPU is capable of VT-x but it may be disabled. Virtualization applications other than Hyper-V are not supported in Hyper-V virtual machines, and are likely to fail.

With nesting enabled, a guest virtual machine can install its own hypervisor and run its own guest VMs. In this case, Hyper-V exposes the hardware virtualization extensions to its virtual machines. In contrast, the diagram below shows Hyper-V with nested virtualization enabled.

The Hyper-V hypervisor takes full control of the hardware virtualization capabilities (orange arrow), and does not expose them to the guest operating system. The diagram below shows Hyper-V without nesting. Nested virtualization makes this hardware support available to guest virtual machines. This prevents guest virtual machines from running Hyper-V. Typically, once Hyper-V starts, it prevents other software from using these processor capabilities. Hyper-V relies on these processor extensions to run virtual machines (e.g. Modern processors include hardware features that make virtualization faster and more secure. Netsh interface ip add dnsserver “vEthernet (VmNat)” address= You may also want to assign a DNS server: Get-NetAdapter "vEthernet (VmNat)" | New-NetIPAddress -IPAddress 192.168.100.2 -DefaultGateway 192.168.100.1 -AddressFamily IPv4 -PrefixLength 24 Note that the gateway IP must point to the NAT adapter from the previous step. Next, assign an IP address to the net adapter: Get-NetAdapter "vEthernet (VmNat)" | New-NetIPAddress -IPAddress 192.168.100.1 -AddressFamily IPv4 -PrefixLength 24Įach nested virtual machine must have an IP address and gateway assigned to it. New-NetNat –Name LocalNAT –InternalIPInterfaceAddressPrefix “192.168.100.0/24” Note that the IP addresses are just an example, and will vary across environments: New-VMSwitch -Name VmNAT -SwitchType Internal

This approach is best suited for cases where MAC address spoofing is not possible, like in a public cloud environment.įirst, a virtual NAT switch must be created in the host virtual machine (the "middle" VM). The second option relies on network address translation (NAT). Get-VMNetworkAdapter -VMName | Set-VMNetworkAdapter -MacAddressSpoofing On This is completed with the following PowerShell command. In order for network packets to be routed through two virtual switches, MAC address spoofing must be enabled on the first (L1) level of virtual switch. There are two options for networking with nested virtual machines: The incompatibility only occurs while Hyper-V is running in the VM. Note that simply enabling nested virtualization will have no effect on dynamic memory or runtime memory resize. For virtual machines without dynamic memory enabled, any attempt to adjust the amount of memory while it's on will fail. This means that even if dynamic memory is enabled, the amount of memory will not fluctuate. When Hyper-V is running inside a virtual machine, the virtual machine must be turned off to adjust its memory. You can disable nested virtualization for a stopped virtual machine using the following PowerShell command: Set-VMProcessor -VMName -ExposeVirtualizationExtensions $false For more information on installing Hyper-V see, Install Hyper-V. Install Hyper-V within the virtual machine, just like you would for a physical server.Set-VMProcessor -VMName -ExposeVirtualizationExtensions $true This enables nested virtualization for the virtual machine.

While the virtual machine is in the OFF state, run the following command on the physical Hyper-V host.See the prerequisites above for the required OS and VM versions. Newer Windows operating systems may support enlightenments that improve performance. The guest can be any Windows supported guest operating system.
