Hello.
i'm considering upgrading my linux box that i use for virtualization
(i5-3470, Z77 mb).
at the moment i have a successfully working setup where i pass thru a
gtx970 to a windows vm.
i also have an aging 4 port network card, see below:
------
04:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit
Ethernet Controller (Copper) (rev 06)
04:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit
Ethernet Controller (Copper) (rev 06)
05:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit
Ethernet Controller (Copper) (rev 06)
05:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit
Ethernet Controller (Copper) (rev 06)

i was thinking of replacing this card since i at the moment can't
assign this in a good way, my only option now is to assign all 4 ports
to same vm which doesn't really help.
so, i was thinking of getting a x99 based mb, a xeon e5 v4 cpu and a
I350-T2 network card that supports sr-iov.
A consumer board will probably not support it.
question is, how do i know that the main board also have the necessary
bits for sr-iov support?
as i understand it, the bios have to do something too to make it work.
You would have to ask the OEM.
main boards i was considering was MSI X99A gaming 7 and also ASUS
X99-E WS.
the msi board have a nice block diagram that says how things is
connected and manual looks abit better
Consumer boards probably won't support SR-IOV, ARI, ACS etc anything you
need to do real virtualization besides just HVM they probably won't have
and the vendor won't care :[ sad as gaming in a VM is common these days.
my thinking was that maybe a workstation mb have higher probability of
better support for more advanced features like this.
but this might be an incorrect assumption.
Yes it would, but as always you need to make sure.
any advice would be welcomed.
If you want to do this for cheap I would pick up a used server from a
few generations ago off ebay that supports it from one of the major
vendors such as dell/hpe, there are many forums that will help you with
this.
