Xen Virtualization in redhat kernel

Latest response


Can some one please tell me what is the significance of below kernel version

title Red Hat Enterprise Linux Server (2.6.18-308.el5xen)
root (hd0,1)
kernel /xen.gz-2.6.18-308.el5

what I have downloaded RHEL 5.8 version and installed on physical servers and now its showing an extension of Xen . and due to this some of the rpm installation fails


This is the kernel you need to run if your system is a paravirtualized Xen virtual machine, also known as a "Xen domain".

If you're running on bare metal hardware with no virtualization, you do not need this package.

Is there any option to migrate/change this to the kernel which can run on bare metal hardware .Actually the server which I installed is now in production phase . so pls advice if we can change to normal kernel as customer facing some issue when they try to install rpm package


Is this server register the RHN or a Red Hat Satellite?

yum install kernel

otherwise mount the DVD, go to the directory with the package

rpm -ivh kernel-2.6.18-308.el5.el5.rpm

edit /etc/grub.conf and check the line


The number should point to the new title (count start at 0)

Kind regards,

Jan Gerrit Kootstra

Thanks Jan,,
