NAT interface is always eth0

[lp]

Im trying to run CentOS 7 as a guest with 2 host only adapter and 1 NAT interface.

I've set Host-only Adapter 1,2 as adapter #1 and #2 respectively and NAT adapter as adapter #3. Everything working fine but I see that NAT interface is always taking the first interface, i.e. eth0. Is there a way to change NAT interface to eth3?

[Perryg]

From the hosts terminal/command window type VBoxManage showvminfo <VM Name> --details and post here. Replace <VM Name> with the actual name of the VM. Use " " if the name has a space in it.

Note if the host is Windows you need to be in the directory that has VBoxManage.exe for the command to work.

Strange you posted in a Linux as host section but it looks like you are running Mac. Is this correct?

I also imagine that you were not root when you created guest, but I need you to confirm that as well.

[lp]

Sorry for that. I'm running a Linux guest on a Mac host. Could you please move this topic to Mac section if you don't mind.

BTW, below is what you have asked.

[lp]

i've posted this query in VirtualBox on Mac OSX. Please feel free to delete this thread.

Thanks,

[Perryg]

Well the logical place to place this is Linux Guest then.

Now the proper layout as far as VirtualBox is concerned looks fine so the issue of the eth* name must reside within the guest. It may be as simple as the way you configured the guest at the beginning. Actually the eth* really makes no difference to how the guest runs but if you want to change that you would need to do it within the guest. See the CentOS folks on how you would achieve that.

[lp]

that's right @Perryg. im trying to deploy one application which is specific on eth names.
I'm already searching how define/change device names from OS (centOS 7) side... opened this thread just to confirm it has nothing to do with VB.


Thanks very much for your quick responses.
