Hi, I followed you instructions, I've build and installed
xen-3.2.0-0xs and xen-libs-3.2.0-0xs.
Now I get this error when I execute xm list:

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

And into the xend.log I have

[2008-04-24 09:48:01 3499] INFO (SrvDaemon:331) Xend Daemon started

I read this is about the python used in the previous version of xen of
mu centos5 linux but I suppose this error is due to the previous

Now I'm running this:

[root@hyp10 ~]# uname -a
Linux hyp10.infolan 2.6.18-53.1.14.el5xen #1 SMP Wed Mar 5 12:08:17
EST 2008 x86_64 x86_64 x86_64 GNU/Linux
[root@hyp10 ~]# rpm -qa | grep xen

And this is the python I have installed:

[root@hyp10 ~]# find /usr/ -name "SrvDaemon.py"

[root@hyp10 ~]# find /usr/ -name "python*" | grep -v doc

How do you suggest me to go on?
