Summary	0002485: Xen ioport and irq mapping functionality broken in 3.0.3-41.el5
Description	After upgrading to CentOS 5.1, Xen's functionality to map i/o ports and irq's (f.e. to access a serial port in DomU) is broken. This is due to upstream bug http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1053 The fix is simple, see attached patch for iopif.py and irqif.py.

hrak 2007-12-04 13:48 reporter ~0006470	Same goes for pciif.py btw, which i missed initially. This also contains 3 occurances of 'dom' on line 160, 174 and 184 which should actually be 'domid'.

mlodi72 2008-02-20 19:13 reporter ~0006915	After having changed the iopif.py, irqif.py and pciif.py the problem persist. No way to use serial port in domU.

andree 2008-04-17 18:43 reporter ~0007146	After applying xen-2485.patch on latest packages of centos 5.1 problem has been solved.

wolfy 2009-11-28 00:21 developer ~0010424	xen-2485.patch seems to be applied xen-3.0.3-94.el5_4.2 (maybe earlier, but this is the version that I have at hand). I guess we could/should close the bug ?
