Xen users - Jun 2006 - xend start error: OSError: [Errno 1] Operation not permitted

Hello,

    I have recently installed xen 3.0.2 from source, but have been
having some trouble getting it working.  I had to make a few changes to
the kernel to support my network card.  After i rebooted and tried to
start xend, I got the following error

Traceback (most recent call last):
  File "/usr/sbin/xend", line 111, in ?
    sys.exit(main())
  File "/usr/sbin/xend", line 93, in main
    return daemon.start()
  File
"/usr/lib/python2.3/site-packages/xen/xend/server/SrvDaemon.py",
line 505, in start
    self.daemonize()
  File
"/usr/lib/python2.3/site-packages/xen/xend/server/SrvDaemon.py",
line 475, in daemonize
    os.setsid()
OSError: [Errno 1] Operation not permitted

and the debug log says

Traceback (most recent call last):
  File "/usr/sbin/xend", line 111, in ?
    sys.exit(main())
  File "/usr/sbin/xend", line 93, in main
    return daemon.start()
  File
"/usr/lib/python2.3/site-packages/xen/xend/server/SrvDaemon.py",
line 525, in start
    self.run()
  File
"/usr/lib/python2.3/site-packages/xen/xend/server/SrvDaemon.py",
line 614, in run
    self.listenVirq()
  File
"/usr/lib/python2.3/site-packages/xen/xend/server/SrvDaemon.py",
line 638, in listenVirq
    virqChan = self.channelF.virqChannel(channel.VIRQ_DOM_EXC)
  File "/usr/lib/python2.3/site-packages/xen/xend/server/channel.py",
line 110, in virqChannel
    chan = VirqChannel(self, virq)
  File "/usr/lib/python2.3/site-packages/xen/xend/server/channel.py",
line 199, in __init__
    self.port = xc.evtchn_bind_virq(virq)
xen.lowlevel.xc.error: (22, ''Invalid argument'')

After searching around the Internet for a while, I found a thread in
this list where someone else had the same problem, and it was suggested
that the problem was a conflict with an older version.  I did have an
older version of xen installed on that machine, but still get this error
after uninstalling it.  Does anyone know of any other possible cause for
this error?
