Bugzilla Bug 1053

On Xen 3.1.0 I'm trying to setup the serial port access from the domU following
the
instructions at http://wiki.xensource.com/xenwiki/InstallationNotes.

So I addedd these configurations to the domU cfg file:
irq = [ 4 ]
ioports = [ "3f8-3ff" ]

When I create this new domU I get this error:
Error: function takes exactly 3 arguments (2 given)

Please post the backtrace from /var/log/xen/xend.log

I have exactly the same. This is on a debian lenny xen 3.1-1. Happened right
after upgrading from xen 3.0.3

my xend.log:

Looks like there is a bug in tools/python/xen/xend/server/irqif.py 

xc.domain_irq_permission is called with keyword argument dom instead of domid
as it should be. This has been fixed in the unstable branch.
This api change seems to have been made in:

which misses this file.
