Hi Konrad,
Frankly, I am confused. XCP(which is similar to Citrix Xenserver but open-source and newer-kernel) requires DDK to build a kernel image. If I understand your suggestion correctly I should be able to
1. Take PVOPS kernel code, compile it in XCP DDK and load it into dom0 2. Take PVOPS kernel code, compile it in domU OS and load it into domU
then, I should be able to get pci-passthrough + shared interrupts between devices working correctly? Please clarify/confirm
Thanks

I think you are confused. The PVOPS kernel does have all these patches..

PVOPS is the *kernel*. Nothing else. You should be able to take, say XCP,
and replace the kernel with the PVOPS kernel if you want too.
