Error during migration to higher version of VMware

Asked By 0 points N/A Posted on -


I’m doing a migration from VMware 2.5x to VI3. After the server is moved to VI3, I have problem in starting VMware.

I received the above error.

Please note: Before the migration, I preserved the MAC address of 2.5 and modified the VMX file by changing the following:

EthernetN.addressType= from vpx to static and changing ethernetN.generatedAddress="xxxxx" to ethernetN.address="xxxxxx"  

Please help me on this!

Error: “Please specify a static Ethernet address for ethernet0. Failed to configure ethernet0.

Error during migration to higher version of VMware


For getting relax from this error one of the vm’s is running as license server and the registration key was registered by using the MAC of the network interface. So  you had to keep the MAC address of this VM.

If you  tried to manually set the MAC address from VMWare client and still  go to the following message:

“The MAC address entered is not in the valid range. Valid values are between xx:xx:xx:xx:xx” 

Then please  removed the vm from ESX inventory and download the vmx file and changed the ethernet0.addressType to static. For this used Notepad+ to change ethernet0.Address = “01:0C:29:B0:27:E1″ value.

It must be notice that delete the original file from the Data store and upload the vmx file back. If you still have something than.

Without an additional setting in the vmx config file you won’t be able to assign a static MAC address in the range your require. To disable mac address checking before boot add the following line in the vmx file. ethernetX.checkMACAddress = “false”
