Assigning a Specific MAC Address to a Virtual Machine
Assign a specific Media Access Control (MAC) address to a virtual machine (VM) if you need to override its default MAC address.
Warnings:
- By default, the everRun software automatically assigns MAC addresses to the VMs. Do not override the default settings unless you have specific requirements (for example, to support software applications that are licensed on a MAC-address basis).
- If you change the Static System IP address, any MAC addresses automatically assigned to the VMs will change when the VMs reboot, because the everRun software generates MAC addresses for the VMs based on the system IP address. To prevent changes to the MAC address for a VM, set a persistent MAC address as described in the following procedure. Contact your network administrator to generate a valid MAC address for your environment, and remember to update any firewall rules based on the new MAC address.
Prerequisite: Before modifying the MAC address for a virtual machine, you must shut down the VM.
To assign a specific MAC address to a VM
- Open the Virtual Machines page (see The Virtual Machines Page).
- Select a VM and click Shutdown.
- When the VM has stopped, click Config to display the Reprovision Virtual Machine wizard.
- Click Next on each wizard page until the Networks page is displayed. (If applicable, see Reprovisioning Virtual Machine Resources to configure additional VM resources.)
- On the Networks page, locate the network to modify and make a note of the current MAC address in case you need to restore it.
- Type the new address in the MAC address column, or leave the text area blank to allow the everRun software to automatically assign the MAC address.
- Click Finish.
