Re: [Xen-devel] Q on ioctl support in netfront/netback

[ravi kerur <rkerur@xxxxxxxxx>]

Hi Konrad,

Using PCI passthrough(I believe it is via config file changes) prevents other domU's accessing the NIC correct? If I use it, would the network transmit/receive still happen via netfront/netback drivers?

Thanks

You could use PCI passthrough. This way the NIC would be visible in your
DomU and you could fiddle with the registers.
