Here is some information:

# /etc/init.d/xencommons start
Starting xenstored...
Setting domain 0 name...
Starting xenconsoled...
[root at XenTester su]# /etc/init.d/xend start
[root at XenTester su]# which libvirtd
/usr/local/sbin/libvirtd
[root at XenTester su]# which xend
/usr/sbin/xend
[root at XenTester su]# locate libvirt.so
/usr/lib64/libvirt.so.0
/usr/lib64/libvirt.so.0.9.4
/usr/local/lib/libvirt.so
/usr/local/lib/libvirt.so.0
/usr/local/lib/libvirt.so.0.9.10
[root at XenTester su]# service xend status
[root at XenTester su]# ps -ef|grep libvirtd
root      2242     1  0 21:52 ?        00:00:00 libvirtd --daemon
root      3295  3112  0 21:59 pts/0    00:00:00 grep libvirtd

Can you see if it is normal here?

Thanks,
