If Linux VIFO driver acts as VI, as per spec SR-PCIM is "Software responsible for the configuration of the SR-IOV capability, management of Physical Functions and Virtual Functions" So if we use kvm who does above work of SR-PCIM ? Does VIFO driver provide any methods for PF & VF communication. Thanks & Regards, Bharat ��.n��������+%������w��{.n�����o�^n�r������&��z�ޗ�zf���h���~����������_��+v���)ߣ�
