This hook has been obsoleted by the native support of SR-IOV.
The sriov vdsm hook enables SRIOV support in oVirt.
The hook works as follows:
- receives a VF via its os nic names, i.e.
- gets its pci address
- detaches it from the os
- creates an xml representation of the device for libvirt domain
- adds it to the guest xml
Will attach 2 sr-iov VFs to vm
RHEL6 sr-iov notes:
- Enable IOMME:
- Intel CPU, pass intel_iommu=on to the kernel command line
(dmesg grep “Intel-IOMMU: enabled” # make sure that iommu is enabled)
- AMD CPU
- Load sr-iov PF and VF
- Intel Corporation 82576 Gigabit Network Connection:
modprobe igb max_vfs=7
7 is max for 82576 card
