[Fedora-xen] RHEL5 - Xend will not start after software upgrade
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

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.

RE: [Fedora-xen] RHEL5 - Xend will not start after software upgrade
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? ----------------------------------------> Date: Tue, 25 Mar 2008 15:45:15 +0000 > From: berrange@redhat.com > To: ukhanlists@hotmail.com > CC: xen-users@lists.xensource.com; fedora-xen@redhat.com > Subject: Re: [Fedora-xen] RHEL5 - Xend will not start after software upgrade > > On Tue, Mar 25, 2008 at 11:41:27AM -0400, Ubaidul Khan wrote: >> >> 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.
