CentOS 7 host for VirtualBox virtual machines

Just some helpful links for a new CentOS 7 installation

passwd root  / generate great random password

CentOS 7 Firewalld "d for daemon": get-started basics

Install wget if you just did a CentOS 7 minimal install:  yum Install wget

You will need at least one user who will be a member of the vboxusers group which is created when VirtualBox is installed; adduser username

Install VirtualBox 4.3 on CentOS 7  (Note that some "ungraceful" exits from ldconfig while rebuilding vboxdrv are normal on a system that does not have a previous version of virtualbox to uninstall.)

Headless

No-GUI: Instructions to run VirtualBox headless - start at section 3

If you are going to run virtual box "headless", you will want to install the extension pack from the non-gui CentOS command prompt.  Find the latest extension pack here on oracle.com and then use wget to download it.  Once you have the file, install it, making sure to use the latest file name.

wget http://download.virtualbox.org/virtualbox/4.3.26/Oracle_VM_VirtualBox_Extension_Pack-4.3.26-98988.vbox-extpack
# VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.3.26-98988.vbox-extpack

Enable remote desktop
# VBoxManage modifyvm Rhiannon --vrde on

Start it, headless
# vboxmanage startvm <vmname> --type headless 

VirtualBox with graphical user interface thanks to GNOME

GUI: Install GNOME desktop


Once you have GNOME running, look for a menu choice to start VirtualBox.  Details vary slightly from one version of CentOS to the next.

Other - Subversion

For a command-line subversion client, consider svn 1.8 instructions but be careful to adjust the repo address for CentOS7.  Chnaging to /centos/7/ in the baseurl works for the content of /etc/yum.repos.d/wandisco-svn.repo

[WandiscoSVN]
name=Wandisco SVN Repo
baseurl=http://opensource.wandisco.com/centos/7/svn-1.8/RPMS/$basearch/
enabled=1
gpgcheck=0

Other - Win2012 ISO

If installing Windows server guests, FREE ISO for Windows Server 2012 Essentials

Other - VNC

If installing VNC for remote gui access: vnc-server-installation-on-centos-7  and remember to use -nolisten tcp -localhost for security in your /etc/systemd/system/vncserver@:1.service file.  Remember that the :1 refers to the port when added to 5900 thus :1 means you connect on port 5901. You do not have to use 5901; you can use another port number.
