Conventions used

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

Code in text: 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: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

for <variable> in <list>
do
command <variable>
done

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

if <condition>;
then
<statement 1>
...
<statement n>
else
<statement alternative>
fi

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

$ sudo grep -E 'svm|vmx' /proc/cpuinfo
$ sudo dnf install qemu-kvm virt-manager virt-viewer guestfstools virt-install genisoimage

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Select System info from the Administration panel.”
