Hello,
Recently I ran yum update on a RHEL5 x86_64 machine and as part of the update, the following packages were installed:
Updated: xen-libs-3.0.3-41.el5.x86_64 Updated: xen-libs-3.0.3-41.el5.i386 Installed: kernel-xen-2.6.18-53.1.14.el5.x86_64 Updated: xen-3.0.3-41.el5.x86_64
After the update, I rebooted the machine. Now, I cannot get xend to start:
[root@saleen xen]# /etc/init.d/xend start Starting xend: [ OK ]
[root@saleen xen]# ps -ef | grep xend root 4080 1 0 11:27 ? 00:00:00 python /usr/sbin/xend start root 4081 4080 0 11:27 ? 00:00:00 python /usr/sbin/xend start root 4264 3109 0 11:45 pts/1 00:00:00 grep xend
[root@saleen log]# tail -f /var/log/xen/xend.log self.obj = klassobj() File "/usr/lib64/python2.4/site-packages/xen/xend/server/SrvDomainDir.py", line 39, in __init__ self.xd = XendDomain.instance() File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomain.py", line 655, in instance inst.init() File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomain.py", line 76, in init self._add_domain( File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomain.py", line 139, in xen_domains domlist = xc.domain_getinfo() Error: (13, 'Permission denied')
I googled around, but I can't find anything useful. Some people mentioned they rolled back to the previous version of the kernel-xen, xend, xen-libs. I would like to find the reasons behind the problem before rolling back. Any assistance is greatly appreciated. Thanks

That means you have a mis-matched version of the kernel vs userspace.
Make sure you have applied all RHEL-5.1 updates, and have rebooted into the new kernel. The new userspace won't work with old kernel & vica-verca.

FYI, yum on my machine was configured with RHN repositories. Is yum supposed to handle these dependencies in way so people dont end up in the same situation I am in? ----------------------------------------
