Disregarding GUI you can always put your Linux system to sleep from command line. This is especially useful if you GUI breaks from some reason and becomes unresponsive to suspend command or you wish to suspend your system remotely. Suspend also known as sleep is a state where your system current running state is saved directly to RAM and remains dormant until awaken by some sort of wake up event such as pressing power button, opening laptop lid or mouse move.

Since RAM is a volatile memory and requires electrical power to hold data your system while in suspended state continues to use electrical power. To suspend/sleep your Redhat/Fedora system you can enter the following linux command: 
rhel7~]$ systemctl suspend

In this tutorial we will describe how to install Virtualbox Guest additions on Fedora Linux virtual machine. The rule of thumb here is that the most recent Fedora Linux version requires up to date Vitualbox installation. Having said that, it is possible to install Virtualbox Guest additions for most recent Fedora Linux using outdated Virtualbox installation, however the process would not be that straight forward. Therefore, if possible, before you continue to read, see what version of Virtualbox you are running and compare it with the version found on the official Virtualbox website. The more recent VirtualBox version the less likely you are to run into X server version incompatibility and to get error: 
"unknown X server version"
Apart of the updated Virtualbox version this guide also assumes functional Fedora Linux installation with working Internet connection. Lastly, the aim here is to provide a generic guide for Virtualbox Guest additions on Fedora Linux virtual machine and as a result reader needs to adjust some of the following linux commands to is your envireoment.

Step 1: Mount Guest additions

Start your Fedora virtual machine and mount Virtualbox Guest additions by navigating to Virtual box menu -> Devices -> Insert Guest Additions CD image The following message will pop up: installation of Virtualbox Guest additions - Fedora
Hit cancel and navigate to Virtualbox Guest additions mounted directory using your terminal: 
# mount | grep -i vbox
/dev/sr0 on /run/media/fedora/VBOXADDITIONS_VERSION type iso9660
# cd /run/media/fedora/VBOXADDITIONS_VERSION
# ls
32Bit  AUTORUN.INF  cert  runasroot.sh            VBoxSolarisAdditions.pkg        VBoxWindowsAdditions.exe
64Bit  autorun.sh   OS2   VBoxLinuxAdditions.run  VBoxWindowsAdditions-amd64.exe  VBoxWindowsAdditions-x86.exe

$ su -c 'yum localinstall --nogpgcheck \

Last time, we talked about custom kernels in Debian-based systems. This time we go to "the other side" and will also talk about customizations, namely how to customize packages on Fedora systems. For this you are not required to have any prior experience on the matter in order to build packages, but a will to learn and read manual pages or other resources is always welcome.

Our article will focus on Apache as packaged by Fedora, and what we will do is modify some of its build options in order to better fit our needs. After all, Linux and Open Source are all about customization, so why not get exactly what we want? With that being said, let's start with our tutorial.
