Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Install the nova-docker plugin."

A block of code is set as follows:

... 
[xenapi] 
xenapi_connection_url=http:// 
xenapi_connection_username= 
xenapi_connection_password= 
... 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

[DEFAULT]
compute_driver = xenapi.XenAPIDriver
...

Any command-line input or output is written as follows:

# git add -A
# git commit -a -m "Add Test Compute Node 02"

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Create the first Node Group Template for Spark slave node."
