[Xen-users] [HELP!]ERROR: do_evtchn_op: HYPERVISOR_EVENT_channel_op failed: -1

[yang jianguo <yangjianguo_biy@xxxxxxxxxxxx>]

This has troubled me some days yet.
I download the xen by hg at Aug 29, when i "xend
start",it successed, but put this message:
ERROR: do_evtchn_op: HYPERVISOR_EVENT_channel_op
failed: -1
I check the xend.log, it said Error recreating domain
info:id=0

When type "xm list",it looks ok.But when i create a
guest os, nothing but a black window displayed. 
the xm list said the guest os is running.

So i close the guest os, message jump out:
local host kernel: unregister_netdevice: waiting for
tun0 to became free. Usage count=1.
then lots of messages like :
Message from syslogd@localhost at Fri Aug 29 06:25
2005 ...
localhost last message repeated 7 times.
dispayed.

I reboot the machine, the console said:
...
shuting down mDNSResponder services  [fail]
shuting down nifd services           [fail]
unregister_netdevice: waiting for tun0 to became free.
Usage count=1.
unregister_netdevice: waiting for tun0 to became free.
Usage count=1.
unregister_netdevice: waiting for tun0 to became free.
Usage count=1.
unregister_netdevice: waiting for tun0 to became free.
Usage count=1.
...

What is the problem? HELP!
