Installing VirtualBox

The (VirtualBox) website has a lot of quality documentation including:
  • End-user documentation
  • Technical documentation
  • Source code repository timeline
  • List of changes (changelog)
This article will briefly cover the installation process. Both i386 and AMD64 (x86_64) versions are available.
You will need to be the root user for the following tasks. Login to a root shell or "su -" in a terminal window.
Download the RHEL repo config.
  • Note: As an alternative, you may choose to download and install individual RPMS rather than configuring the repository. That procedure is documented on the VB web site and will not be covered here.
cd /etc/yum.repos.d
wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo
  • Optionally add a line "enabled=0" if you do not want the repository to be enabled by default. This will require adding "--enablerepo virtualbox" to yum commands to access the repository.
The installation of VB will require the building of kernel modules. If DKMS (Dynamic Kernel Module Support) is installed it will be used and will simplify kernel upgrades. Installing DKMS from the EPEL repository is recommended before installing VirtualBox. Don't forget to configure the yum-priorities plugin. Installing DKMS will pull in required development dependencies.
yum --enablerepo=epel install dkms
<!> A forum user notes that all but the latest version of DKMS from Dell may be buggy.
If DKMS is not used and the development environment and kernel source are not already installed:
yum groupinstall "Development Tools"
yum install kernel-devel
You may also choose to only install a minimum set of individual development tool packages (at least gcc and make are required) rather than the groupinstall which some may consider overkill. Replace "kernel-devel" with "kernel-PAE-devel" if using a PAE kernel. If you are not using a standard CentOS kernel, you must acquire and install the source for your kernel from wherever you got the kernel. Do not try to use VirtualBox with a Xen kernel, nor to install a Xen kernel in a Guest OS.
  • Note: For CentOS as a Guest OS the same packages are used to build the "Guest Additions" drivers.
Install the RPM:

yum install VirtualBox-5.1

NFS mount add in fstab _netdev instead of default | firewall-cmd --list-all

By OK -
Redhat recommends us to add  _netdev  option for NFS file system in /etc/fstab. So that they can be mounted after starting the networking service. Alternative ways to refer to partitions: Label : LABEL=label Network ID Samba : //server/share NFS : server:/share SSHFS : sshfs#user@server:/share Device : /dev/sdxy (not recommended) Example #1 //192.168.1.134/share_name /mnt/share_name cifs username=server_user,password=server_password,_netdev 0 0 ^ Path to your share ^ Mountpoint ^ Username ^ Password ^ See note A Note A: The  _netdev  options makes sure the mount is only attempted AFTER a network connection has been established. Example #2 10.10.10.1:/vol1/fs1 /data nfs defaults,_netdev 0 0 ============================ [root@localhost ~]# firewall-cmd --list-all public   target: default   icmp-block-inversion: no   interfaces:   sources:   services: dhcpv6-client high-availabi...
