how to assign second nic for KVM VM

[mkeil77]

Hi,

 

i'm still quite new to unRAID and just setup my first system.

among some docker applications i also setup a Windows 7 VM which works all perfectly fine.

The only thing i need to setup, where i could not find the right answers is how i could setup the second on board NIC in the VM.

The first one is already working but i like to setup the second one in the VM to be used only for the internet connection.

 

my setup is:

unRaid Version: v6 rc2

Mainboard: ASRock - C2750D4I

 

please find also attached the config of my VM

 

thanks a lot in advance for all the replies

Did you see this:  http://lime-technology.com/forum/index.php?topic=39638.0

hi,

 

no i have not seen this particular post. the problem is if i follow that one, after changing the syslinux.cfg my system is not longer reachable over the network.

the both NICs have also the same vendor ID, not sure if that has anything to do with that.

How many total NICs are on your system?  It only two, you can only pass through 1.

[mkeil77]

Yes only two. My idea was to have this first one as now for unRAID and all docker apps and the second NIC for the Windows VM to connect to the Internet.

but what do I need to change to pass through then only one?

[mkeil77]

unfortunately i got this still not up and running.

as mentioned in my previous post, as soon as i update the syslinux.cfg I'm not able to reach my unRAID system any longer over the network.

assuming thats because both network cards have the same vendor ID.

my question is now how can i pass through only one of the NICs or setup the second one for unRAID as br1 so i can assign it maybe to the VM?

please find below my lspci output.

 

both NICs are already showing in the dashboard of unRAID but not below the network settings.

 

i appreciate any help in this matter

OK after a couple of more research it seems that my MB does not support direct passthrough.

 

So i decided to create a second bridge for ethic and assign that to my KVM VM.

lets see hot this will go
