A possible workaround would be to spoof the GuestOS MAC address via Windows registry key change. There is no simple way to retain or determine MAC addresses for a VM with VMware View if the VM is not yet assigned to a user. In this situation VMs that have not been assigned to users yet or belong to floating pools would need to retain their MAC addresses. One of the possible reasons to retain MAC addresses could be applications that have their licensing model tied to MAC addresses. Now, you are probably asking why you would want to retain MAC addresses for non-persistent desktop pools.

If recompose is selected for the entire pool, whether the default image was changed.

If VM is not assigned to a user, whether the desktop pool is persistent and whether the recompose is on the entire pool or on a list of VMs.

If the VM is assigned to a user, always use recompose to ensure MAC address is preserved.

The choice between recompose and delete-then-recreate is made by View Manager based on following conditions: In VMware View 4.5 and later if a VM is assigned to a user their MAC address is retained after recompose operations.įor non-persistent pools and for VMs that haven’t yet been assigned to a user, a recompose operation will be performed as delete-then-recreate resulting in MAC address change.įor VMware View brokers as long as a VM is scheduled for recompose, it will only do recompose. The article does not discuss the retention of MAC addresses. I have previously written about how Linked Cloning operations work under the hood, read on Part 1 and Part 2 of my article “ VMware View 4.5 Linked Cloning Operations Explained”. Because of the high number of recourses utilized during these operations VMware decided to change the basics of those operations for VMware View 4.5. In VMware View 4.0 and earlier linked cloning operations were a little more CPU and IO intensive. vmx file.A common question from VMware View administrators is if the MAC addresses in each VM are retained after a recompose or refresh operation. Now you should be able to launch a VM with the static MAC address you defined in. Replace the MAC address field with your own.

vmx file with a text editor, and add the following fields. vmx file is located: # cd vmfs/volumes/datastore1/ vmx file of your VM directly, after logging in to the ESXi host.įirst, turn off the VM to which you want to assign a static MAC address.Įnable SSH access to your ESXi host if you haven't done it already. The solution is, instead of using vSphere GUI client, editing.

Then what if I want to assign any arbitrary MAC address to a VM?įortunately, there is a workaround to this limitation. If you attempt to set any arbitrary MAC address outside this MAC range, you will fail to launch the VM, and get the following error. However, this GUI-based method only allows you to choose a static MAC address from 00:50:56:xx:xx:xx, which is VMware-reserved MAC address range. If you want to change this default behavior and assign a static MAC address to your VM, here is how to do it.Īs you can see above, VMware's vSphere GUI client already has a menu for setting a static MAC address for a VM. When you create a VM on VMware ESXi, each network interface of the VM is assigned a dynamically generated MAC address. How can I set a static MAC address on VMware ESXi VMs?

However, when I attempt to start a VM with a static MAC address, the VM fails to start and throws an error '00:0c:29:1f:4a:ab is not an allowed static Ethernet address.

Question: I want to assign a static MAC address to a virtual machine (VM) on VMware ESXi.
