Unable to start xend on sles 9 boxes

Unable to start xend on sles 9 boxes

[David F Barrera]

The last couple of days I have been unable to start xend on a couple of i386
boxes with SLES 9: (Note: A box with FC4 worked just fine.)


x235:~ # xend start
x235:~ # xm list
Error: Error connecting to xend: Connection refused.  Is xend running?

You need this patch:

This is in our queue, but it's not been pushed because something else is
broken.  You could apply this one manually for now, or you might find that
removing old xend.log files is sufficient (this code runs when it rotates the
log file, which happens when that reaches 1MB in size).

Cheers,

Ewan.

Ewan,

Thanks. Actually, I did exactly that yesterday to get around.
