Instead, you can bind virtio devices to vfio-pci (no-iommu mode). You can enable it like: $ modprobe vfio enable_unsafe_noiommu_mode=1 $ modprobe vfio-pci Thanks, Jianfeng > > *Error: bind failed for 0000:00:04.0 - Cannot bind to driver vfio-pci > Error: unbind failed for 0000:00:04.0 - Cannot open > /sys/bus/pci/drivers//unbind* > > *Any input?* > > *Regards,* > *Ranjith* > > > > Regards, > Ranjith > > > On Tue, Sep 12, 2017 at 2:31 PM, Pragash Vijayaragavan <pxv3620@rit.edu> > wrote: > > > Hi, > > > > try modprobe igb_uio/ vfio-pci /uio_pci_generic > > > > > > > > Thanks, > > > > Pragash Vijayaragavan > > Grad Student at Rochester Institute of Technology > > email : pxv3620@rit.edu > > ph : 585 764 4662 <(585)%20764-4662> > > > > > > On Tue, Sep 12, 2017 at 4:54 AM, RanjithKumar <ranjithdvk@gmail.com> > > wrote: > > > >> Hi All, > >> > >> I have installed DPDK in open stack lunched virtual machine and Modrobe > is > >> failing with below error > >> > >> modprobe: FATAL: Module uio not found > >> > >> Any input? > >> > >> Regards, > >> Ranjith > >> > > > > ^ permalink raw reply [flat|nested] 3+ messages in thread
