Hi,

This is regarding SRIOV in Rhel7. I have added intel_iommu=on in grub.cfg file. When I attach Virtual Function to VM and I try to poweron the VM, I get the below error:

[root@Dell-Rhel7 ~]# virsh start rhel64x64GA

error: Failed to start domain rhel64x64GA

error: internal error: early end of file from monitor: possible problem:

qemu-kvm: -device vfio-pci,host=42:10.2,id=hostdev0,bus=pci.0,addr=0x8: vfio: failed to open /dev/vfio/vfio: Permission denied

qemu-kvm: -device vfio-pci,host=42:10.2,id=hostdev0,bus=pci.0,addr=0x8: Device 'vfio-pci' could not be initialized

We are facing this problem with both Emulex and Intel adapters. Please help me to resolve this issue.

Thanks,

Murali.
