Hi!
I don't know if it's something that can cause trouble in the future so
I'm posting it so that someone more fit to judge can decide:

This is a "real" box (not xenolinux) and, as you can see, I have irq
lines up to 217!
This is with MSI/MSI-X enabled in kernel 2.6.x... With MSI disabled the
irq lines stay under 24.
127 is too low or this MSI stuff doesn't matter in a xen environment?
Regards,
Nuno Silva
