Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Words and Phrases
| Search for | Example | Results |
|---|---|---|
| A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
|
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Using Boolean Operators
| Search for | Operator | Example |
|---|---|---|
|
Two or more words in the same topic |
|
|
| Either word in a topic |
|
|
| Topics that do not contain a specific word or phrase |
|
|
| Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
| A combination of search types | ( ) parentheses |

Overview
Xen is a Hypervisor providing services that allow multiple computer operating systems to execute concurrently on the same computer hardware. Xen is currently available for the IA-32, x86-64 and ARM computer architectures.
Kernel-based Virtual Machine (KVM) is a virtualization infrastructure for the Linux kernel. KVM supports native virtualization on processors with hardware virtualization extensions. KVM has also been ported to FreeBSD and Illumos in the form of loadable kernel modules.
KVM originally supported x86 and x86-64 processors and has been ported to S/390, PowerPC, and IA-64. An ARM port is in progress, KVM hypervisor porting to ARM Cortex-A15 is made available by Virtual Open Systems.
Libvirt is an open source API, daemon and management tool for managing platform virtualization. You can use it to manage Linux KVM, Xen, VMware ESX and other virtualization technologies. Graphical interfaces use it, such as Virtual Machine Manager, as do command line interfaces (virsh), and higher level tools like oVirt.
This package discovers Xen and KVM virtualization solutions using libvirt as an API via shell connection.
