Re: [Xen-users] problem on starting xend

[Steven <wangwangkang@xxxxxxxxx>]

Could any one give some help on this?
I install Xen from source on a FC 8 machine. Following the instruction
in the README file, everything seems fine. However, the problem is
that I can not start xend. The error message is that

Traceback (most recent call last):
 File "/usr/sbin/xend", line 155, in <module>
   sys.exit(main())
 File "/usr/sbin/xend", line 132, in main
   start_blktapctrl()
 File "/usr/sbin/xend", line 116, in start_blktapctrl
   start_daemon("blktapctrl", "")
 File "/usr/sbin/xend", line 82, in start_daemon
   os.execvp(daemon, (daemon,) + args)
 File "/usr/lib/python2.5/os.py", line 354, in execvp
   _execvpe(file, args)
 File "/usr/lib/python2.5/os.py", line 392, in _execvpe
   func(fullname, *argrest)
OSError: [Errno 2] No such file or directory

I guess the problem is caused by the python os.py. However, on the
same machine, the xen kernel installed by yum install xen has no
problem with starting xend using the same command.
This is strange.
