Re: [Xen-users] xen 3.4.3 -- xend service failing to start --Permission denied

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

   Traceback (most recent call last):

line 871, in xenschedinfo
       sched_id = self.xc.sched_id_get()
   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 /vmlinuz-2.6.18-194.26.1.el5xen ro
root=/dev/VolGroup00/LogVol00
        module /initrd-2.6.18-194.26.1.el5xen.img


Thanks,

Joe
