[dpdk-dev] SR-IOV with vfio-pci

[Deepak Gowda]

Hi,

I'm trying to run test-pmd application with virtual functions bound to
vfio-pci.
I'm able to bind and unbind the virtual functions from ixgbevf to vfio-pci
and vice-versa
And i'm seeing the below VF Initialization failure error, i can't seem to
figure out what's going wrong here,

EAL:   using IOMMU type 1 (Type 1)
PMD: eth_ixgbevf_dev_init(): VF Initialization Failure: -15
EAL: Releasing pci mapped resource for 0000:04:10.0

Here's some more information:
I'm using dpdk-17.11.
Created Virtual functions on Intel 82599ES 10G cards.
Bound these vfs to vfio-pci.
And tried to run the test-pmd.


Any advise is appreciated.
Thanks,
