How to Virtualize OS X Lion on Windows

Update: Sorry about the delay guys, this page has been updated so that Xcode 4.1 does not crash anymore. (August 17, 2011).

If you've tried to virtualize previous versions of OS X, you know that it is a very tedious and time consuming process. This new guide works by giving you a simple VMWare Image. This means that the OS has already been pre-configured on a hard drive. For the most part, there is no need to mess around with boot flags or installation settings

This guide will show how to setup a fully working OS X Lion 10.7 on a Windows machine. This process will take about an hour but most of the time is spent downloading files. This was done on Windows 7 but should work on any OS as long as it meets the requirements.

Requirements
A laptop or desktop computer that supports virtualization (most newer computers do).
At least 1 GB of RAM (the more, the better).
VMWare Workstation (this is a paid program but a little research will get you it for free).
VMWare Hard Drive (vmx files, it is in a self-extracting .exe file) Here is a mirror in case that one isn't working anymore.
OS X Lion (VMDK File)

Instructions
Before you start, make sure that you have enabled Virtualization in the BIOS of your computer. This is usually disabled by default by computer manufacturers.

An updated video has been made of all the new steps:



1. From the file downloaded, double click on Mac OS X Lion VMware Files.exe. Click Run thenYes. This will decompress the files.

2. Once done, a folder named Mac OS X Lion VMware Files will appear, double click it.


3. You will need to follow the instructions in this video to unlock VMWare. Instead of using the files from the video, use the files from Step 2.



4. From Step 1, you should have also gotten a folder named Mac OS X Lion. Open that up and open the file named Mac OS X Lion.vmx. Double-click this file. It will open in VMWare Workstation.

5. On the left column, click on Edit Virtual Machine Settings. In the Memory tab, you can edit how much RAM OS X will get. In the Sound tab, change to Specify host sound card, change it to your sound card. After the machine has started and sound doesn't work, change to Use default host sound card.

6. At the bottom of the box is an Add button, click it. Select Hard Disk from the left, click Next. Choose Use and existing virtual disk.

7. Browse for the Mac OS X Lion Installer.vmdk that was downloaded from the torrent. ClickFinish. Click OK to close the box.

8. On the left column, click Power on this virtual machine.

9. If a box asks to repair the image, click Repair. Once the box comes up, click I copied it, clickOK. A message about the CD Drive may come up, just click OK.

10. The machine should power up in a few moments, ready to go. For ease of use, click in VMWare Workstation, click File > Add to Favorites.

11. You should now have a Install Mac OS X screen. At the top, click Utilities then Disk Utility. Select the 42.45 GB Hard Disk. Click on the Erase tab. Now you can name your hard drive what you want. Then click on Erase. Click Erase again.

12. Once the process is done, close out of the Disk Utility box, the Install screen will come back up. Click Continue, Agree. Select the 40GB Hard Disk to install Lion. Click Install. The process will take about 30 minutes. Once it's done, the account setup will start. Once that's done, Lion will start.

13. To be able to use the machine in full screen, in OS X open Preferences, click on Displays. Now select the resolution of your monitor. Now in VMWare, click on the Full Screen button on the toolbar (10th button from the left).

14. Now you're done, you can use this OS as a normal to install programs.

Creating a New VMWare Workstation Virtual Machine

VMware – Virtual Networking

Let’s talk something about virtual networking today. In VMware everything is virtualized. Even the networks also. Before proceeding to our discussion, lets see how a common physical network looks like.

If you see in this image, the two systems are connected to a router/switch (in this case, the router is also acting as switch) to enable networking between them. All these three devices are physical, and those are connected using the cables. So when you configure this type of networking A Switch, Cables and Network cards are mandatory. But is it possible to enable the same type of networking between two machines without any cables, physical switches or physical nics in between them ?

Yes, absolutely using the Grand Grand Virtualization Master VMware.

Using VMware Virtualization software we can create virtual machines, we can add virtual nics to those virtual machines, we can also create virtual switches and finally we can connect those virtual machines using these virtual devices. But one thing is absolutely not needed in this type of networking that is Cables. Everything is virtualized here. Now lets see how a simple virtual network looks like.

In the image beside, VM1 and VM2 are examples of Pure Virtual Networking. That means, there is no physical device at all between VM1 and VM2. They can communicate each other in all aspects using the Virtual Networking. But if you take VM0, VM1(it has two nics), VM3 are connected to respective Virtual Switches using the Virtual Nics added to them . The communication between these VM’s also takes place using the Virtual Switches which they are connected. But aprat from the internal communication, they are also able to communicate with external networks i.e Prod LAN1, Prod LAN2 and Mgmt LAN. That means they are able to communicate with the other physical machines in their external network or on the internet.

How this external communication happens?

Let me explain this in detail, we are creating virtual machines on ESX servers right, so these ESX servers contains Physical nics attached to them. And these physical nics again connected to Physical Switches using the cables. So we are using One Port on Physical Switch for this ESX server, and the other ports on the same switch are used for other ESX servers or other Physical Machines. So when you create a virtual machine on this ESX server, we will add virtual nics to it. Those virtual nics are connected to Virtual Switch on the same ESX server. So what we are doing here is, we are creating a Virtual Switch using the Physical Nics which are attached to the ESX server. When we initiate a request on the virtual machine, it goes to virtual switch (means physical nics of ESX server), from there it forwarded to physical switch. And as you switch is an intelligent device, it can transmit the same request to the target machine if the target is in same network. Other wise, it will forward it to another switch or router. In this way a Virtual machine communicates with the Physical network.

What is a VNIC and vSwitch?

A VNIC is a virtual nic which is added when we create a virtual machine. Its a software based nic (virtualized nic) which enables the communication between vm’s or between a vm or vSwitch.

A vSwitch is nothing but the physical nic which is installed on the ESX server. The same physical nic shared to all the virtual machines hosted on that particular ESX server. So it is acting as a Switch in this scenario. We can connect/configure 1016 virtual machines to use a physical nic, in other words we can create a virtual switch that contain 1016 ports. No physical switch provides these many ports in real time. And in other case, we can create the vSwitch with out any physical nic also. Its purely software based vSwitch (the same is used between VM1 and VM2).

Here you go, a virtual networking looks like below when you manage it through Virtual Center. In the below image, Help,Exchange1, Mandarin, DC2, SIF, Kurzweil are the virtual machines which are connected to vSwitch0 (2 physical nics on ESX server). In the same way iSCSI and Exchange1 are connected to vSwitch1. Here vSwitch0 and vSwitch1 are different networks (assume them as Production network and management network respectively). This the networking belong to one ESX server only, if we are configuring a Cluster using multiple ESX servers, we need to configure them in the same way. All must have identical configuration, otherwise vMotion, HA and DRS will not work properly.

I hope this is informative for you. Thanks for visiting my blog.

Train signal CBT, CBT Nuggets are some of the video tutorials available in the current market. You can see the demo videos in Youtube also for real-time configurations i suggest you to watch them.
