Even Scientific Linux has limitations. This is a short list found in Scientific Linux 5.4

We strive for perfection. Any goal less than that is sortof silly. But we are also realistic. Not everything is going to be perfect. This page documents what we know is broken, or not living up to it's potential.


Xen based virtualization is fully supported. However, Xen-based virtualization requires a different version of the kernel to function. The KVM hypervisor can only be used with the regular (non-Xen) kernel.

While Xen and KVM may be installed on the same system, the default networking configuration for these are different. Users are strongly recommended to only install one hypervisor on a system.

Clusters and SELinux

SELinux in Enforcing mode is not supported with the Cluster Suite; Permissive or Disabled modes must be used.


Removable storage devices (such as CDs and DVDs) do not automatically mount when you are logged in as root, or in a non graphical enviroment. If you are in a graphical enviroment, you will need to manually mount the device through the graphical file manager.

Alternatively, you can run the following command to mount a device to /media:

mount /dev/[device name] /media

X resolution

When running the bare-metal (non-Virtualized) kernel, the X server may not be able to retrieve EDID information from the monitor. When this occurs, the graphics driver will be unable to display resolutions highers than 800x600.

To work around this, add the following line to the ServerLayout section of /etc/X11/xorg.conf:

Option "Int10Backend" "x86emu"
