Change MAC address of SR-IOV Virtual Function inside VM

Hi.

Is any way to change MAC address on VF inside VM without touching host?

Is it possible to add additional MAC addresses which NIC's driver pass through VF

When MAC inside VM is changed via

$ sudo ip link set eth0 address fa:16:55:55:55:55

Log message appears in host system:

Dec 24 15:08:29 localhost kernel: [685436.750320] ixgbe 0000:01:00.0 p5p1: VF 3 attempted to override administratively set MAC address

Dec 24 15:08:29 localhost kernel: [685436.750320] Reload the VF driver to resume operations

and traffic stops flow through eth0. Then I should change MAC on VF in host to fix this

$ sudo ip link set p5p1 vf 3 mac fa:16:55:55:55:55

Log message appears in host system:

Dec 25 15:12:14 localhost kernel: [685661.582284] ixgbe 0000:01:00.0: setting MAC fa:16:55:55:55:55 on VF 3

Dec 25 15:12:14 localhost kernel: [685661.582291] ixgbe 0000:01:00.0: Reload the VF driver to make this change effective.

and traffic starts flow again.

I have same bonding use case and issues as described in GUEST with bonding and VLAN support on CentOS 6.5 with Intel SR-IOV

We use Intel 10G NICs
