It seems that there are a number of physical interrupts > that are not used, and some are shared: If the device interrupts are aliasing then that is because the physical interrupt lines are physically wired together. There's nothing you can do about that, except try moving PCI cards to different slots (if one of your devices is not built in to the mobo chipset) and hence use a different physical interrupt line for that PCI card. Which interrupt number is shared? If you 'xm debug-key z' and then 'xm dmesg', a bunch of IO-APIC related debug output should be printed. This might yield some interesting info (probably just confirming that your devices really are wired to the same interrupt line). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
