My motherboard (Supermicro X8SIL-F) has 3 ethernet ports, 1 for IPMI and another 2.

 

Is it possible to have Unraid running on 1 of them and the VMs running off the other?

sure thing,

create 2 bridges

1. br0(xenbr0) linked to eth0  use for unraid, I think it is a default config when booting eith xen kenrel

2. create br1(xenbr1) l linked to eth1 and use that to connect your VMs to.

 

the best config IMHO is to create new bridge linked to eth1 for every VM

this way you can have a unique static IP for each VM

not sure if you can have static IP when single bridge is used.

I've got 2x Windows VMs connected to xenbr0 and each has a distinct static IP so it does work OK.

 

Thanks both.

 

The next question that springs to mind is... how do I create a br1 bridge that links to eth1? lol

 

I see in the cfg you specify: vif = [ 'mac=00:16:3e:a1:bc:a4,bridge=br0' ] but I imagine there's more to it than just specifying it in there?  Or is the mac the real physical mac of eth0 and eth1 and so using the correct values there will just work?  and if that is the case would it just be something along the lines of

 

VM1: vif = [ 'mac=00:16:3e:a1:bc:a4,bridge=br1' ]

VM2: vif = [ 'mac=00:16:3e:a1:bc:a4,bridge=br2' ]

VM3: vif = [ 'mac=00:16:3e:a1:bc:a4,bridge=br3' ]

I am not sure how to do this in UnRaid v6

 

check out the posts in virtualization section for unraid v6 bridge config

i think you do this in unraid network.config file

or maybe using the WebGui

I had the same question. Running a x9scm board with three Ethernet ports.

Bear in mind if you choose to do it that way all network traffic will have to go through your external switch rather than the internal br0 vSwitch xen creates.

Question are:

* Will it be faster if it went through the internal vSwitch?

* Can the internal vSwitch handle parallel 1GBit connection at full speed?

 

Typically vSwitches are insanely fast. In fact in ESX land you can set the vNIC to be 10Gbit for this reason. I wonder if this is a trcik we are missing here.

This is something I have been trying to figure out since I set up my Xenserver setup, and asked about previously in looking at moving to unRaid as dom0. My thought is could I set up two brX's, as described above [br1 - eth0, br2- eth1] and then use some linux-jujitsu to route some or all internal traffic (since I will be mostly targeting file transfers to the array) to br1 and all external-to-the-box traffic to br2?

 

Or, is there an easier way to accomplish this? Someone had mentioned vSwitch, and that it wasn't what Tom was using, but I guess we could install it ourselves?

 

I really want to make the networking work just right. My Xenserver has four VM's running, and for reasons I have given up trying to understand, two of them write to the array at blistering speeds (75-100MB/sec) and two of them at 10-20MB/sec. I checked which NIC they were using, etc., but the only thing I can think, and not sure how to check is that the two fast ones are using a virtual connection (which might be written to the datastore-SSD in the process of the transfer) and the others are bouncing up to the router and back in to the box. In any case, I have given up trying to get it right in that setup, and vowed to get it right when I move to 6.x.
