Hi,

    I have a requirement to assign the transmit and receive queues of a NIC card to different guest operating systems so that the guests can directly submit transmit requests to controller and receive packets from NIC controller without going through a middle layer.  The NIC controller is not SRIOV capable and there are a few MSI-X vectors available.

 

What would be the best way to implement the requirement in Xen? I am new to Xen but have experience in a similar virtualization framework.

 

Any input or pointer to document will be appreciated.
