mac address change issue

[cosminf]

Hello All,

I am trying to change the mac address of a linux vm with a mac address that is outside the "00:50:56:XX:YY:ZZ" rage by following these steps:

-remove from the vmx config:

                       ethernet0.generatedAddress    

                       ethernet0.addressType    

                       ethernet0.generatedAddressOffset

-add to the vmx config: 

    ethernet0.addressType = "static"

    ethernet0.address = "new_mac_address"

I successfully changed the mac address, but now I can't access the vm from outside the network.

I was wandering if this is the correct way to change the mac address, if not, please advice.

I also tried running the following commands on the vm, but ended up with the same result.

  ifconfig eth0 down

  ifconfig eth0 hw ether new_mac_address

  ifconfig eth0 up

  ifconfig eth0 |grep HWaddr

Looking forward to seeing your toughs on this issue. Thanks,

Hi...

kindly, chck the following guide.. page 154-155-156

http://pubs.vmware.com/vsphere-51/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-511-networking-guide.pdf

It talks about that the static MAC address must be in certain range and the .vmx file will be edited in different way..
I hope it helps u.. :smileyhappy:

is the security policy "MAC Address change" of your virtual switch portgroup set to accept?

Yes it is.

After extensive troubleshooting I fixed the issue by commenting out the SUBSYSTEM line from /etc/udev/rules.d/70-persistent-net.rules corresponding to eth0.

Thank you for your assistance.
