# installation of VirtualBox on both machines as well, according to the description here:
#: http://help.ubuntu.com/community/VirtualBox (including the procedure for USB + RDC). That is I simply used
#: <code>sudo apt-get install virtualbox</code>
# htop and mc are installed as well

=== Setup of VMs ===

VMs should primary run on cedeusgeonode server (e.g. GeoNode, OTP, WYP, test stuff), except perhaps for the TileServer VM
# creation of VM basicubuntu1404 to be used later for tests
#* 4 CPUs, 8GB Ram, 100GB, nat-ing (behind firewall)
#* Ubuntu 14.04 with openssh, LAMPS, XFCE and XRDP is installed (admin ss...g, pw for mySQL is admin pw)
#* VM creation commands:
#*:<code>VBoxManage createvm --name basicubuntu1404 --ostype Ubuntu_64 --register</code>
#*:<code>VBoxManage modifyvm basicubuntu1404 --memory 8192</code>
#*:<code>VBoxManage modifyvm basicubuntu1404 --cpus 4</code>
#*:<code>VBoxManage modifyvm basicubuntu1404 --nic1 nat</code>
#*:<code>VBoxManage createhd --filename basicubuntu1404.vdi --size 100000</code>
#*:<code>VBoxManage storagectl basicubuntu1404 --name "SATA Controller" --add sata --controller IntelAhci</code>
#*:<code>VBoxManage storageattach "basicubuntu1404" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium basicubuntu1404.vdi</code>
#*:<code>VBoxManage storagectl basicubuntu1404 --name "IDE Controller" --add ide --controller PIIX4</code>
#*:<code>VBoxManage storageattach basicubuntu1404 --storagectl "IDE Controller" --port 1 --device 0 --type dvddrive --medium /home/ssteinig/ubuntu-14.04-server-amd64.iso</code>
#* starting the VM with remote desktop connection to install ubuntu:
#*:<code>VBoxHeadless -s basicubuntu1404 --vrde on &</code>
#*:=> Note: the option <code>--vrdeproperty port=7777</code> does not seem to have an effect, but the console tells me the connection port for VNC (e.g. 3389)
#* starting the VM and wanting to install Ubuntu I actually got the following message
#*:''"This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot – please use a kernel appropriate for your CPU"''
#*:=> Turns out that it should be resolved via enabling the virtualization option the computers boot menu, according to this blog post: http://hereirestinremorse.wordpress.com/virtualbox/this-kernel-requires-an-x86-64-cpu-but-only-detected-an-i686-cpu-unable-to-boot-please-use-a-kernel-appropriate-for-your-cpu/ <br /> However, my virtualization option was switched on, but: I forgot to specify in createvm the ostype as "Ubuntu_64" (not just "Ubuntu"). So then I tried correcting this with modifyvm, but this did not work. Hence, I deleted the VM (<code>"VBoxManage unregistervm basicubuntu1404 --delete"</code>)and created a new one ;)
# after rebooting: modify the repository location for update (don't want to use cl) in ''/etc/apt/sources.list''
# shut down the VM
# removed the disk image: 
#: <code>"VBoxManage storageattach basicubuntu1404 --storagectl "IDE Controller" --port 1 --device 0 --type dvddrive --medium none"</code>
# enable ssh connection to the VM: 
#: <code>VBoxManage modifyvm basicubuntu1404 --natpf1 "ssh,tcp,,10022,,22"</code> (and perhaps other connections, e.g. apache 80, tomcat 8080)
# restart the VM, do a software update and install XFCE. (I think XRDP does not need to be installed because the VirtualBox has is already included: default port as above: 3389)
