Xen users - Dec 2007 - Cannot start Xend . Xen 3.2 rc4. Permission denied error 13.

I end up with the same error after building and running xen-stable 3.2-rc4 on
both Ubuntu 7.10 and Fedora Core 6. I am using AMD64 builds.

I have carefully followed the instruction on the xenbits.xensource.com on
building Xen unstable.

After booting with the new Xen and dom0 kernel, I cannot use any Xen tools
(such as xm) from Dom0. I have tried restarting Xend but it fails with the
same errors.

The error I get is:

root@localhost xen]# xm list
Error: Unable to connect to xend: No such file or directory. Is xend
running?
xend.log:
xend 5409] ERROR (__init__:988) Exception starting xend
((13, ''Permission denied''))
Error: (13, ''Permission denied'')

xend-debug.log:
domctl operation failed -- need to rebuild the user-space tool set?
Exception starting xend: (13, ''Permission denied'')


What am I missing here?

Cheers.

Did you have a previous Xen install on your machines?  If so, you need to make 
sure it''s completely removed before installing a new version of Xen.  
Otherwise, the tools have a nasty habit of getting their versions confused 
and causing errors like this.

HTH,
Cheers,
Mark

Thanks Mark. I root caused the problem to incorrect version of xen-related
python scripts being used. The xen make {world, install} was putting the new
scripts under /usr/lib*/python tree whereas my system had /usr/lib*/python24
in its path first.

Cheers.
