Hi i'm using FC5 and atfer installing xen successully....xend is not
starting...following is the error...


Error: Error connecting to xend: No such file or directory.  Is xend
running?


i checked the  xend.log file which has this log entry

i searched on the net ..but didnt get any satisfactory solution that we
havent tried.

I'm a beginner in XEN  .....it'll be great if anyone comes up with a
solution
Thanks in advance

[Adrian Chadd]

It seems due to a mismatch between the xen kernel version they've rolled in the
latest FC5 and the Xen user utilities.

The neccessary packages have now been moved from updates-testing to the
regular 'updates'  channel. So a simple 'yum update' should pull in all
the bits needed to get a working Xen install with new kernels.

I'm sorry I was too busy to test these until they made "updates" proper.

However, having upgraded now to the new xen and libvirt packages, it still 
doesn't work, and reverting to 2.6.17-1.2157_FC5xen0 does _not_ fix the 
problem. I now have a machine which can't boot any of its slices.

I will test more xen and libvirt packages if they can be made available. 
I've got about 24 hours before I'll need to chicken out and either find 
the old packages on a stale mirror somewhere, or restore from tape.

Same as mine. Hm! I wish I had more time to figure this one out.

Hi, still found some clue for an explanation (see
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=211745) about that
message.

It seems the used xen patch in the src.rpm rely on Xen 3.0.3... Probably
a stressed guy mistake ;-)

Think we should wait for next release.
