Red Hat Enterprise Linux Advanced Platform
Virtualization Support in Red Hat Enterprise Linux
A guest instance in Red Hat Enterprise Linux 5 Virtualization can be run in one of two different modes: Para-Virtualized (PV) and Fully-Virtualized (FV).
The Para-Virtualized mode provides high performance but requires a Xen-enabled version of the guest operating system.
The Fully-Virtualized mode allows unmodified guest operating systems to be run, but requires the hardware to provide Virtualization enablement (Intel-VT or AMD-V).
Red Hat generally supports different versions of Enterprise Linux as a guest as well as a well-defined list of third party operating systems. Please refer to the virtualization support matrix2 for details on the supported combinations of host and guest operating systems and architectures.
Red Hat also provides a set of optimized "para-virtualized" drivers for fully virtualized guests, that will directly talk to the hypervisor instead of emulated hardware. These drivers require the host operating system to run Enterprise Linux version 5.1 or later. The virtualization support matrix2 provides detailed information about the available PV driver support.
For supported third-party operating systems listed in the virtualization support matrix2, Red Hat will provide commercially reasonable efforts to isolate problems customers encounter and provide solutions for defects in the Red Hat Enterprise Linux Virtualization environment. However, Red Hat is not able to provide any support for the third party operating system itself.
If the problem falls into the domain of the third-party OS, Red Hat will request that the customer contact the OS vendor directly or Red Hat will engage with the vendor on behalf of the customer for further investigation. Please note that a support contract with any third-party OS vendor will be required for continued support.
If the problem falls into the domain of the Red Hat Enterprise Linux Virtualization environment, Red Hat will continue to provide support in accordance with the defined Service Level Agreement associated with the Red Hat Enterprise Linux subscription.
Red Hat will also provide para-virtualized drivers for a selected sub-set of the supported third-party guest operating systems.
1. Please note that running in a virtualized environment may be subject to the third party operating systems license agreement.
2. Please see chart below for details.

1. Support for para-virtualized x86-32 guests on a x86-64 host environment is planned to be fully supported in a later update to Enterprise Linux 5.
2. Red Hat is actively working on optimized PV drivers for Windows guests. These drivers will lead to a significant improvement in the performance of Windows guests and move the support level to "Optimized." Red Hat will announce details on the availability at a later point in time.
3. 64-Bit Windows guests have not been tested and considered lower priority than 32-Bit guests due to a lack of visible adoption. Red Hat plans to add support at a later point in time.

The basic unit of failover in MSCS is the group. The group is the set of tasks or items that must all be on the same node of the cluster for a particular objective to be accomplished. Each group can be on only one node in the cluster at a time, but different groups can be owned by different nodes. Each group contains one or more resources. A resource is a process or data item that is managed and watched by the cluster service of the node on which the group resides. If a resource fails, the cluster service will first attempt to restart the resource, but, if that is unsuccessful, the cluster service will move the group to another node if one is available.
As stated above, the group should contain all resources that must be on the same node for processing to occur. In that sense, the resources of the group are interdependent. More pragmatically, often one resource must be online before another resource can configure itself and start correctly. The second resource is said to "depend" on the other. The Cluster Administrator allows you to designate one resource as depending on another. If this is done, the Cluster service will not start the resource until the one it depends upon is started. If a resource fails, the resources that depend on it will be taken offline, and, if it restarts, the resources will be returned to an online state.
Many of the resource types that ship with MSCS have requirements for dependencies. The only resource types that do not usually depend on another resource are the Physical Disk, and IP Address. The Network Name resource must depend upon an IP address so that it can register the name and address pair with WINS. The other resources have similar requirements.
The cluster service will start resources in the order of their dependencies. In the above example, a typical group going online would start the Disk and IP Address resources first, because they have no dependencies. The Network Name resource would be started next, and after that starts, the File Share resource would start, because both the Disk and Network Name resources are online.
Note that it is not possible to have resources in different groups depend on one another. Because different groups can reside on different nodes, there is no way to guarantee that the dependencies can be satisfied.
You can also define dependencies where none are required to satisfy logical dependencies that you create. For instance, you may not want your Internet Information Server (IIS) virtual web page describing the
Running a backup in Linux
To execute a simple backup using TAR in Linux, enter the following command at the prompt:
tar -cvf /dev/st0 /home<enter>
(home is used as an example of a directory.)
For more information on the different switches for TAR, enter the following command at the prompt:
man tar<enter>
Other useful tape related commands in Linux:
- mt -f /dev/st0 status -- information regarding the tape drive
- mt -f /dev/st0 rewind -- rewind the media
- mt -f /dev/st0 reten -- retension the media
- mt -f /dev/st0 erase -- erase data on the media
- tar -tvf /dev/st0 -- verify the contents of the tape using tar
- tar -xvf /dev/st0 -- restore the contents of the tape using tar
