Hi,
Just to let you know that the invalid instruction error above went away
when AVX was enabled using host model cpu mode in the VM.
Thanks,

I haven't added it yet, because as of the moment I do not have an access to
the built DPDK library I was using. I was just linking it with my DPDK
application.
I tried to debug it with GDB and disassembled it, the invalid instruction
was "vzeroupper" which occurs at rte_eal_init, somewhere when i
Hi Thomas,
I thought I was clear enough, sorry for the confusion.
I am running a DPDK application in a guest VM which uses one VF. This VM
runs on top of the host that has an x540-at2 NIC and uses the ixgbe driver.
The issue was that every time I run the DPDK application in the VM it
errors an
Thanks again. So there is a possibility that vf will fail with DPDK due to
not fully supported pf. Please correct me if I'm wrong.
Cheers,
Pepe

I see thanks.
I'm actually running my DPDK application on a guest OS but I'm always

Pepe ,
Was the DPDK library compiled on a different machine and the used in the VM? It
looks like it has been compiled for native AVX (hence the vzeroupper). Could
you dump cpuinfo in the VM and see what instruction set the VM supports?

Please Jose, better describe your use case in order to have the right answer.
The standard SR-IOV use case is to use a rec

Yes
But probably that
hw->mac.type = ixgbe_mac_X540
apply also to x540-at2.
Please to try to add it and send the patch if it works.

Hi,
I can't find a MACRO for this nic in rte_pci_dev_ids.h, does this mean this
isn't supported as of this moment ?
I only saw MACROS for x540t and x540t1.
Cheers
