Setting up osgeo vm

Setting up a OSGeo VirtualBox-VM on Lautaro with SuseLinux - but using command line (because creating the VM via the graphical interface vboxgtk did not work properly). The general documentation was taken from here: http://stdioe.blogspot.com/2012/01/creating-virtual-machine-with.html

Steps:

install virtualbox on server/computer (done by Daniel, needs admin rights of course)

create a VM based on Ubuntu:

VBoxManage createvm --name osgeo  --ostype Ubuntu --register

check it is there:
```
VBoxManage showvminfo osgeo
```
set the memory/ram:
```
VBoxManage modifyvm osgeo --memory 8192
```
(which is 8GB)

check the memory/ram:

VBoxManage showvminfo osgeo | grep "Memory size"

set the number of cpu's to use (here 4):
```
VBoxManage modifyvm osgeo --cpus 4
```
set the network connection/routing
```
VBoxManage modifyvm osgeo --nic1 nat
```
Here we use 'nat'-ing instead of a bridge

create a harddisk of 100GB size:

VBoxManage createhd --filename osgeo.vdi --size 100000

define the VM's disk controller:

VBoxManage storagectl osgeo --name "SATA Controller" --add sata --controller IntelAhci

mount the disk:

VBoxManage storageattach "osgeo" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium osgeo.vdi

add DVD device:

VBoxManage storagectl osgeo --name "IDE Controller" --add ide --controller PIIX4

load the DVD device with the Ubuntu VM/osgeo iso file:

VBoxManage storageattach osgeo --storagectl "IDE Controller" --port 1 --device 0 --type dvddrive --medium yyy/osgeolive7.iso

starting VM
```
VBoxHeadless -s osgeo -n -m 7777 & 
```
The -s is for start, 7777 defines the port for conecting with VNC, and the & is for keeping the VM running when I disconnect from the server. Headless actually means, that we have no monitor...
don't forget to install VNC Viewer (e.g. RealVNC), and then connect via the defined port - to "146.155.xx.xxx:7777"
... do a real install of the osgeo VM, etc.
how to do a mapping for ssh & ftp, so that the guest VM can be reached from the host machine is described here: http://blogs.oracle.com/rmanus/entry/virtualbox_how_to_ftp_from
In particular one has to do the following:
```
/usr/bin/VBoxManage setextradata name_of_vm "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/HostPort” 4021 
```
```
/usr/bin/VBoxManage setextradata name_of_vm "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/GuestPort” 21
```
```
 /usr/bin/VBoxManage setextradata name_of_vm "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/Protocol” "TCP" 
```
- Note, if a "Error: failed to start machine. Error message: Configuration error: Failed to get the "MAC" value (VERR_CFGM_VALUE_NOT_FOUND)" appears, then it may be necessary to change the network adapter to PCnet-FAST III (Am79C973), according to this Blog entry
