Re: [Xen-devel] pci-passthrough and shared interrupts

[Ritu kaur <ritu.kaur.us@xxxxxxxxx>]

Konrad/All,

I have been asked to look into the option of using pvops kernel(which do not have pci-passthrough + shared interrupts issue) and needed some inputs 

1. Does pvops run on Fedora Core or any specific distributions I need to use?
2. Does it have some form of gui interface to control/manage domU's

Inputs/Pointers much appreciated.

Thanks

You also need the patches in the drivers/xen/pciback directory.

Jeremy has been pulling those out of my git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git pv/pciback-2.6.32

Don't worry about it. It will do MSIs.
