Macs are the only computers that allow you to run Mac OS X Lion Server (or any OS X flavor) along with Windows and Linux. Virtual machines on non-Apple PCs can’t run Mac OS X. Apple doesn’t permit running Mac OS X on non-Apple hardware in its user license agreement, so the virtualization software makers don’t enable it.
Vm Server For Mac Os
Imagine a Mac running two virtual machines — Lion Server and Windows 7. Both are running on a Mac OS X host. In each virtual machine window, you can control that operating system as you normally would run applications, configure settings, and access the Internet.
When the virtual machine is a server, users on the network access it as they would any other server. If multiple virtual machines run on a server Mac, the users see each as a separate server.

With virtualization, there’s a host operating system (OS) and one or more guest OSes. The host OS (for instance, Mac OS X or Mac OS X Server) boots the real computer. On a Mac, a guest OS can be Mac OS X, Windows, Linux, or Unix.
Each guest OS runs in a virtual machine, which is a kind of a virtual reality for the guest OS. The guest OS thinks it’s running on a real computer. Although real hardware’s behind the scenes, the guest OS doesn’t have direct control over the hard drive, graphics, and other hardware: These pieces of hardware are virtualized in the virtual machine.

VMware Desktop Hypervisors: VMware Workstation and VMware Fusion: Local Mac, Windows and Linux Virtualization Desktop Hypervisor products from VMware provide IT pros, developers and businesses alike with a powerful local virtualization sandbox to build, run or support apps of any kind. Virtualization on your Mac. Parallels Desktop uses a special type of virtualization: a hardware-assisted full hardware virtualization that relies on Intel VT-x technology and allows for simulation of the whole computer with its hardware and software. This simulated environment is called a virtual machine (VM) and enables a Virtual PC on your Mac. A virtual machine server (VM server) hosts or runs virtual machines that run various operating systems and act as full computing platforms on their own through emulation and virtualization. Software developers use VM servers for testing software in different environments without actually getting the hardware for those environments, thus saving. How to Find a MAC Address in VMware and Hyper-V. There might be a time when your network team asks you to check on a MAC address coming from your virtualization infrastructure this could be for a number of reasons. Or you have the MAC address of a virtual machine and have no idea which virtual machine the MAC address belongs to. If your environment is small it shouldn’t be too hard to do.
For example, a virtual machine’s hard drive (the boot drive) is actually a file on the host Mac. This file can be dozens of gigabytes, containing the complete guest operating system and its applications, settings, and documents.
The virtual hard drive file is stored on the Mac’s real hard drive, but the guest OS doesn’t control the entire drive. The virtualization software creates the virtual machine and keeps the guest OS believing that it’s living in a real computer — kind of like The Matrix, but without Keanu Reeves.
Another type of virtualization software runs directly on “bare metal,” which means it doesn’t use a host OS. To picture it, remove the Mac OS X host and the Mac applications. Eliminating the host OS decreases the complexity and uses less RAM and processing power.
vSphere provides several schemes for automatic allocation of MAC addresses in vCenter Server. You can select the scheme that best suits your requirements for MAC address duplication, OUI requirements for locally administered or universally administered addresses, and so on.
The following schemes of MAC address generation are available in vCenter Server:
- VMware OUI allocation, default allocation
- Prefix-based allocation
- Range-based allocation
After the MAC address is generated, it does not change unless the virtual machine's MAC address conflicts with that of another registered virtual machine. The MAC address is saved in the configuration file of the virtual machine.
Preventing MAC Address Conflicts
The MAC address of a powered off virtual machine is not checked against the addresses of running or suspended virtual machines.
When a virtual machine is powered on again, it might acquire a different MAC address. The change might be caused by an address conflict with another virtual machine. While this virtual machine has been powered off, its MAC address has been assigned to another virtual machine that has been powered on.
If you reconfigure the network adapter of a powered off virtual machine, for example, by changing the automatic MAC address allocation type or setting a static MAC address, vCenter ServerAcrobat pro for mac serial number. resolves MAC address conflicts before the adapter reconfiguration takes effect.
For information about resolving MAC address conflicts, see the vSphere Troubleshooting documentation.
