RHEL 5, FC 7, and CentOS 5 Guests Installed with Virtualization Affects Performance of Virtual Machine

Details

The Red Hat Enterprise Linux 5, Fedora Core 7, and CentOS 5 high-level virtualization installation option installs the Xen hypervisor and a XenLinux kernel. You might experience a number of performance and functionality issues when running Xen and XenLinux inside a virtual machine.

Guest OS may not be able to ping other network IP addresses

Solution

To avoid these issues, do not select the Virtualization option when you install these guest operating systems.

If the guest operating system is already installed then:

Choose the right kernel from the GRUB prompt to boot into the non-virtualization kernel.
or
Edit the /boot/grub/menu.lst file to comment the Virtualization kernel from booting.
Note: For more information on how to edit boot options in menu.lst, refer to your Linux distribution documentation.
