The final eight bits of the MAC address are set to a hash value based on the name of the virtual machine’s configuration file.įor example, if a machine's IP address was 192.34.14.81 (or in hex, 0xc0220e51) and the configuration file was hashed to the value of 95, the MAC address would have the following value: 00:05:69:0e:51:95 References:.

4) On the right panel there is mac address, select the manual radio button and then enter the new mac address there. 3) Select the network adapter in question. As a solution to this problem you might want to specify a resolving event for this alarm, so once MAC address is changed, you no longer see this alarm in an opened state. This approach eliminates the conflict between MAC addresses created manually and those automatically generated by vCenter or assigned to VMkernel adapters. The alert gets triggered on the initial run, after the collision is detected, vCenter Server changes the MAC address of the VM that's why it doesn't match with the original one. 1) Right click on the VM then select Edit Settings. When you manually set a MAC address in VM settings, the prefix (first three octets) is preserved while the second half of the address can be customized. The first 16 bits are set to the same values as the last 16 bits of the console operating system’s primary IP address. You can change the mac address via the vSphere client if you stop the VM and then do.vSphere 5.5, 6.5, VMware Workstation 15Īffects products: Outdated VMWare solutions: VMware ESX, VMware GSX ServerĪccording to the VMware OUI allocation scheme, the hypervisor generates MAC addresses that consists of the VMware OUI 00:05:69 and the last three octets generated by the following algorithm:.

Switch to the Performance tab and start the 'Resource Monitor'. Signature: MAC address belongs to the range ConditionsĪccording to the VMware OUI allocation scheme, a MAC address has the format of 00:50:56:XX:YY:ZZ, where 00:50:56 represents the VMware OUI, XX is calculated as (80 + vCenter Server ID), and YY and ZZ are random two-digit hexadecimal numbers.īased on this scheme, we can determine the vCenter Server Unique ID, from the servers' MAC address: On Windows 7 - Open Task Manager - Look for processes with the name, 'vmware-vmx.exe', note the PIDs.
