Hi,
I try to get xend to start, when I start "xend start" I get the
following
errors in the log and debug files.
What I don''t understand is the last line in debug log which says:
"Couldn''t
listen on localhost:8000: (98, ''Address already in
use'')", because I have
disabled http server in xend-config.sxp, changed the port to 3000 and there
is nothing else running on port 8000, so xen should not even touch port
8000.
I have other machines where xen runs without problems.
Xen version is 3.02
Any ideas what could be wrong here?
Gerald

If I do other changes in this file, they take effect, so the config file is really used. The most curious thing is that port 8000 is not used on this system.

In my experience, xend is not always fully and cleanly "restartable" (for example, at least the network-script only runs on the very first xend start, not after a stop and further start), so it might let this port open even after being stopped and started again.

RE: [Xen-users] Xend does not start, invalid argument
Hi, The problem was solved by removing and reinstalling xen and tools. Seems to be some kind of version conflict.
