I had this issue after doing an update. The repos replaced the kernel in my
grub with the centos xen. Manually changed it back to the one provided by gitco.

Subject: [Xen-users] xen 3.4.3 -- xend service failing to start --
Permission denied
Hi Folks:
I am trying to start a domU on a Xen 3.4.3 dom0 based on CentOS 5.5 but
it keeps giving me message that says:
libvir: Xen Daemon error : internal error failed to connect to xend
libvir: Xen Daemon error : unable to connect to 'localhost:8000':
Connection refused
I tried 'service xend restart' but that didn't help. After digging a bit
I found the following error message in /var/log/xen/xend.log:
[2011-01-04 13:28:15 16215] ERROR (SrvDaemon:349) Exception starting
xend ((13, 'Permission denied'))
Traceback (most recent call last):

Error: (13, 'Permission denied')
Here is the output from xend-debug.log (note that I tried 'sysctl -p
/etc/sysctl.conf' earlier):
Xend started at Tue Jan 4 13:28:15 2011.
sysctl operation failed -- need to rebuild the user-space tool set?
Exception starting xend: (13, 'Permission denied')
But I don't understand what these messages are trying to tell me. Can
you suggest how this error can be fixed?
Here is my /boot/grub/grub.conf file:
default=0
timeout=5
hiddenmenu
title CentOS (2.6.18-194.26.1.el5xen)
root (hd0,0)
kernel /xen.gz-3.4.3

module /initrd-2.6.18-194.26.1.el5xen.img
Thanks,
Joe
