xend start - failing ...

xend start - failing ...

[Nitin Kamble]

Hi List,

I am trying to get the xen-unstablw working. Followings is what I have
done so far.

1. I got the tarball from the xen website.
2. make world - successful
3. make install - successful
4. make install-twisted - successful
5. xend start - failed with the following error message

[root@lmicro1 xeno-unstable]# xend  start
ERROR: Could not obtain handle on privileged command interface (2 = No
such file or directory)
Traceback (most recent call last):
  File "/usr/sbin/xend", line 118, in ?
    sys.exit(main())
  File "/usr/sbin/xend", line 96, in main
    from xen.xend.server import SrvDaemon
  File "/usr/lib/python2.2/site-packages/xen/xend/server/SrvDaemon.py",
line 38, in ?
    import channel
  File "/usr/lib/python2.2/site-packages/xen/xend/server/channel.py",
line 4, in ?
    xc = xen.lowlevel.xc.new()
xen.lowlevel.xc.error: (2, 'No such file or directory')


I am new to xen as well as to python. And don't really understand what
is  happening here. I couldn't find anything like this on the mailings
list archive.
  BTW I am doing this on RH 9 distribution.

  What is going wrong here? How can get over the above error?

Thanks in Advance,
Nitin

What does 'uname -a' say? You should see kernel version 2.6.8.1-xen0.

If it's 'xenU', or not a Xen kernel at all, then you need to reboot
into your -xen0 kernel.

You need to modify your grub config and then reboot into xen/linux.

Thanks Ian.

One more questions, 
What is the difference in xeno-unstable.bk and xen-2.0.bk ?

Thanks again,
Nitin

Right now, nothing.

We're currently undergoing a feature freeze in the unstable tree,
so the 2.0 tree is typically just a slightly time-delayed version
of the unstable tree. We typically test stuff in the unstable
tree for a couple of days then push it out to 2.0 if there are no
problems reported.

After the official 2.0 release you can expect them to diverge
again, as the unstable tree undergoes changes for SMP guests and
a couple of other major projects we have planned.
