Vm Server For Mac

In most network deployments, generated MAC addresses are a good approach. However, you might need to set a static MAC address for a virtual machine adapter with unique value.

Maintaining and Changing the MAC Address of a Virtual Machine When a virtual machine is powered on, VMware Workstation automatically assigns each of its virtual network adapters an Ethernet MAC address. MAC stands for media access control. A MAC address is the unique address assigned to each Ethernet network device.

The following cases show when you might set a static MAC address:

  1. VMware Organizationally Unique Identifier (OUI) allocation assigns MAC addresses based on the default VMware OUI 00:50:56 and the vCenter Server ID. Prefix-Based MAC Address Allocation You can use prefix-based allocation to specify an OUI other than the default one 00:50:56 by VMware, or to introduce Locally Administered MAC Addresses (LAA) for.
  2. Oct 23, 2017 macOS, the operating system previously known as Mac OS X, is beautiful, stable, and typically attached to a $1000+ MacBook / iMac. If we want to run macOS on a Windows PC, without the very particular hardware required for Hackintosh, a Mac OS X virtual machine is the next best thing.
  • Virtual machine adapters on different physical hosts share the same subnet and are assigned the same MAC address, causing a conflict.
  • Ensure that a virtual machine adapter always has the same MAC address.

By default, VMware uses the Organizationally Unique Identifier (OUI) 00:50:56 for manually generated addresses, but all unique manually generated addresses are supported.

Note: Make sure that no other non-VMware devices use addresses assigned to VMware components. For example, you might have physical servers in the same subnet, which use 11:11:11:11:11:11, 22:22:22:22:22:22 as static MAC addresses. The physical servers do not belong to the vCenter Server inventory, and vCenter Server is not able to check for address collision.

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.

Note: If you use invalid prefix- or range-based allocation values, an error is logged in the vpxd.log file. vCenter Server does not allocate MAC addresses when provisioning a 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 Server resolves MAC address conflicts before the adapter reconfiguration takes effect.
