Hi all,

 

My motherboard has 2 NICs.

Currently I am just using the one NIC for UNRAID - no bond etc

 

Is there a way for me to directly map a VM I have running on this box to the second nic vs it going through that one nic using br0?

 

I apologize if I am not describing the problem well.

 

I would like to dedicate one of the NIC's to the VM only.

 

Thank you

This is what you need:

Hardware that supports VT-d or AMD-Vi (looks good from sig)

(if yes)

The NIC to be in its own IOMMU group

(if no you can try the ACS override patch, supposedly doesn't work on Skylake)

(if we have a yes for both)

Follow this sticky http://lime-technology.com/forum/index.php?topic=39638.0

Thank you bungee91.

 

Looks like I need to readup and understand this a bit better.

 

My system supports VT-d.

I do not know enough about IOMMU - reading up on this now.

 

Shall read through the sticky - its a bit more complicated than I anticipated. Figured it would be like mapping a USB device... guess not.

No worries, it's not too bad to get it once you read.

The main thing (easy way) is to see if the under the about button (or whatever it's called, top right corner) says IOMMU:enabled.

If so, you should be all set, if not, it is likely just a BIOS setting that needs to be changed to have this show up correctly.

Find device ID, stub it (add line to syslinux.cfg), add that section to your XML (from that thread), boot up, all is well.

There are many more details in that thread, and if you have specific questions, just ask, we're a friendly bunch. 

 

Edit: If you're feeling adventurous you could also update to 6.2 Beta 21 (as of writing this), stub the device (same as other method), and then you can use the Edit for your VM and just select the NIC from the available devices listed at the bottom of the page. This removes the having to manually edit your XML to add the NIC to the VM.
