Re: [Xen-users] SR-IOV




Oh got it. 

So If I want to passthrough this device (which is PCIe not PCI ) then is it a same procedure like in PCI passthrough

hiding it from dom0 and assigning it to domU config flie....

also one more since this is pcie device, I can passthrough to more than one domU right?

Thank you
