Hi
I have managed to fix my networking issues.
However, I am still having problems starting xend.
When I try and start xend via "sudo xend start" it appears to start
( and the log claims it has started ) :-
[2005-06-09 20:14:09 xend] INFO (SrvDaemon:610) Xend Daemon started
[2005-06-10 18:56:12 xend] INFO (SrvDaemon:610) Xend Daemon started
[2005-06-10 19:00:28 xend] INFO (SrvDaemon:610) Xend Daemon started

[2005-06-11 12:00:08 xend] INFO (SrvDaemon:610) Xend Daemon started
but "sudo xend status" shows nothing.
ifconfig shows :-

which looks correct.
However, when I then try and start a new domain via
"xm create -c config vmid=1"
I get the following error :-
stewart@gateway:~$ xm create -c config vmid=1
Using config file "config".
(111, ''Connection refused'')
Error: Error connecting to xend, is xend running?
stewart@gateway:~$
Any ideas what''s going wrong here ?
Regards
Stewart

Couldn''t help but notice your on a non-priveleged account and not using sudo on your "stewart@gateway:~$ xm create -c config vmid=1"...could this be the problem? Try as root perhaps.

Stewart, Can you ''ps ax'' to see if xend is actually running (it''ll be a python process). If so, run ''netstat -ltno'' to see if a python process is listening on port 8000 on any interface. If that''s working then check your firewall to see if you are blocking connections to localhost:8000.

OK xend is failing after start somehow. Let''s have a look at your xend-debug.log. Can you also check your memory utilisation (e.g. with ''top'') - you have a load of stuff running and if the oom killer is kicking in then xend may be suffering. Please post replies to the list rather than just to me. Others here may be interested and able to help. For reference, there was a typo in my netstat command line suggestion, should have been ''netstat -ltnp'' to get the process names. (Irrelevant now since xend isn''t running.)

Hi James The good news is that I now have it working. I have managed to create a new Domain based on the ttylinux image and log in as root. I had to manually sudo mkdir /var/lib/xen/xend-db and then sudo mkdir /var/lib/xen/xend-db/domain and sudo mkdir /var/lib/xen/xend-db/vnet as well to get it to start for some reason ?? BTW I have compiled from source and I am using the vmlinuz-2.6.11.10-xen0 and vmlinuz-2.6.11.10-xenU patched kernels if that helps. Many thanks for your help. It''s a very interesting project.

I guess it should still be listed as a bug for 2.0, though. It''s a fairly odd one, as xend does attempt to create the directory. Probably trivial to debug with a bit of tracing, though.

Having empty directories under /var in an install tar ball doesn''t seem the right soloution. We could fix it in install.sh, but by far the best soloution would be to create the directories from within xend. Let''s catch the exception from listdir and create the directory.

Let''s > catch the exception from listdir and create the directory. >i have another idea on solution to this problem. the root of problem is XendDB::fetchall(): this method calls dircache.listdir("dir-name"). python 2.3 has odd behavior: it doesnt complain if the "dir-name" is non-existent, and still returns an empty list. meanwhile, python 2.4 (properly) generates an exception and stops. it is tempting to make a directory in fetchall() in this case, but i dont like that solution, because it would slightly change the semantic of this method. the directory should be created later if needed, when xend saves data. in this patch, i adapt the trick from XendDB of -unstable: returns an empty list in case the directory is non-existent. this is same as the behaviour of python 2.3 on current code. note that this problem only occurs with -stable and -testing, and this patch is against -testing ChangeSet@1.1899 Signed-off-by: Nguyen Anh Quynh <aquynh@gmail.com> $ diffstat xendmkdir.patch XendDB.py | 14 ++++++++------ 1 files changed, 8 insertions(+), 6 deletions(-) _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

And yeah, I know for sure I was running xend as root, as I would have had trouble installing the kit or creating the directories if I hadn''t been. :-/ I was working from a writeup done by some folks at Clarkson that I found by way of https://wiki.ubuntu.com/XenVirtualMachine, so that''s where I appended my notes on the experience. I had meant (still do, too) to add relevant bits to the Xen wiki when I got a bit further along, but I''ve been busy with other projects for a few days. -- One Zone to rule them all, One Zone to find them, One Zone to name them all and in the domain bind them, In the Land of DotCom where the Spammers lie. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

My configuration is as follows:
P4 1.7Ghz, 512MB RAM
Linux distro: XOS
Xen version: 2.0.6 binary
Installed: brctl, twisted, iproute, Zop, python-logging and (all that are
required)
I am able to boot using xen kernel. However, problems arise when i run xend.
Actual output appended below.
# xend start

module xen.lowlevel.xu: This Python has API version 1011, module

Any help would be appreciated.
Thanks in advance.
