Antoher question regarding MSI support.
 
When I have a motherboard where two PCIe slots and one PCI slot share an 
interrupt when using current
Xen and kernel with GSI, when I now use Xen 3.4-unstable and latest 
kernel, it will use the MSI (as the
Two PCIe slots are occupied by realtek NICs and their modules are MSI 
aware). Two different MSI show up 
in /proc/interrupts. 

Does this now mean that I can pass-through the PCI slot into a pv DomU, 
because the GSI is now exclusively
used by the PCI slot (what I could not do before, as NICs shared GSI 
with the network cards)?

For your Info: Xen 3.3.1 and latest kernel will not work for me.

Thanks,
Carsten.
