Could you do 'strace xm list' and post the log as an attachment. 

Also,  I'm wondering if there is an SELinux polcy fix we missed out. Could
you tell me if you have selinux enabled, and in enforcing or permissive 
mode. If enforcing, see if there's anything interesting (AVC denials) in
/var/log/messages, or /var/log/audit/audit.log

An 'lsof -p 2601' would be handy to let us see what ports xend is listening
for connections on.
