MAC Adress mismatch after Cloning

[huhibu]

Hi,

we have a Problem with mac-address allocation to the corrosponding interfaces after cloning a VM.

It always occures if there are more than 6 Interfaces pre configured on VM side.

for example

on OS Level MAC address F1234 = ETH3

on VM Level MAC address F1234 = Interface 6

It only occures with Oracle 7.3. At the OS the Interface renaming to the old Method ETHx is configured.

Any one can help?

Check if the information in VMware Knowledge Base is of help

Hi,

the article do not help.

If I set the Interface to e1000 in VM Ware the cloning works fine, Interface allocation in vSphere match to the underlying Linux, e.g. Interface1 <> ETH0, Interface2 <> ETH1.

If I use VMXNET 3 Interfaces the allocation do not match to the underlying Linux (RedHat&RedHat7), e.g. Interface1 <> ETH1, Interface2 <> ETH0.

I also already delete the 70-persistent-net (RedHat6) rules file  and did a reboot.

My ifcfg-eth1 for e.g

DEVICE=eth0

TYPE=Ethernet

ONBOOT=yes

NM_CONTROLLED=no

BOOTPROTO=none

IP address are not set yet.

On RedHat 6 you can create an customer udev file as attached.

For RedHat 7 it do not work, do some one has an idea to overcome the issue?
