RHEL6: Cannot configure VLANs from a guest using an ixgbe SR-IOV Virtual Function
Issue
- A KVM guest uses an SR-IOV Virtual Function from an Intel 10Gb NIC (82599 or similar) via PCI passthrough
- Configuring a VLAN id for the guest from the host, via
ip link set vf vlan
or the libvirt XML works correctly - Configuring one or more VLANs for the guest using
vconfig
orip link add
does not work
Environment
- Red Hat Enterprise Linux 6
- KVM virtualization
- Intel NIC SR-IOV Virtual Functions (
ixgbevf
driver) used as guest NIC via PCI passthrough
