Win4lin, KVM, QEMU, Virtualbox and Xen are all widely used technologies, used in virtual servers. Fairly often a virtual server run from within a loop filesystem and generally start with a fairly small file (1GB is big for a normal file, but not when it is pretending to be an entire filesystem!)
However things often grow over time.
Here is a nice simple procedure for increasing the size of a loop filesystem, if the filesystem is ext2 or ext3 (the procedure should work for ext4 too, but I havn’t tested it yet)
1. Stop the virtual server that is using the loop filesystem
2. Add some extra space to your loop filesystem file
# dd if=/dev/zero bs=1024k count=1024 >> loop_image_file
This adds 1GB to the end of a file called loop_image_file (make sure to use the append output redirector >> not a single >, otherwise you’ll have an empty 1GB file!)
3. Force a check on the resized/increased filesystem
# e2fsck -f loop_image_file
4. Resize the filesystem within the loop filesystem file
# resize2fs loop_image_file
5. Start the virtual server again

Visio Guy » Blog Archive » Virtualization Visualization with Visio
Whether you are looking to conserve energy, optimize your hardware usage, or rapidly test a wide variety of software configurations, some sort of virtualization is surely in your future.
And if you are a Visio Guy or a Visio Gal, you’ll surely want to make a diagram to better see how your network’s hardware is set up.
I’ve been hopping around the net looking for (mostly-free) Visio-related resources for virtualization. Here’s what I found…
Microsoft Office Visio 2007 Professional Add-In for Rack Server Virtualization (Virtual Rack)
Microsoft offers and add-in that might save you having to do any manual drawing in the first place! This add-in that works with Visio 2007 to help you plan virtualization. It auto-generates your rack and detailed server diagrams from an Excel template, allowing you to visualize where you can save on space and power.

Here are the commands used to open and forward the host’s port 2222 to the guest’s port 22 (SSH Server Port).
Type this into a terminal:
VBoxManage setextradata nameofyourguest "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/HostPort" 2222
VBoxManage setextradata nameofyourguest "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/GuestPort" 22
VBoxManage setextradata nameofyourguest "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/Protocol" TCP
Could also be used to forward PostgreSQL and HTTP:
VBoxManage setextradata nameofyourguest "VBoxInternal/Devices/pcnet/0/LUN#0/Config/postgresql/HostPort" 5432
VBoxManage setextradata nameofyourguest "VBoxInternal/Devices/pcnet/0/LUN#0/Config/postgresql/GuestPort" 5432
VBoxManage setextradata nameofyourguest "VBoxInternal/Devices/pcnet/0/LUN#0/Config/postgresql/Protocol" TCP
VBoxManage setextradata nameofyourguest "VBoxInternal/Devices/pcnet/0/LUN#0/Config/http/HostPort" 8080
VBoxManage setextradata nameofyourguest "VBoxInternal/Devices/pcnet/0/LUN#0/Config/http/GuestPort" 80
VBoxManage setextradata nameofyourguest "VBoxInternal/Devices/pcnet/0/LUN#0/Config/http/Protocol" TCP

Importing / Exporting Virtual Disk Images with Virtual Box : Prosthetic Conscious
Importing / Exporting Virtual Disk Images with Virtual Box
Virtual Box is amazing for an open source project. It comes close to VMWare in usability. Where it falls short is importing and exporting images. There’s no support in the user interface for this. If you feel comfortable using the command line, you can export and import a disk image. Here’s how,
To export:
1. Shut down the VM
2. Use the “VBoxManager clonevdi …” CLI to copy the disk image. On my Mac this was at /usr/bin/vboxmanage
To import:
1. Register the disk image: File>Virtual Disk Manager>Add
2. Create a new VM, and use the disk image you added in step 1
The obvious problem is that the .vdi file is just a disk image. It doesn’t capture the virtual machine. You must know the correct parameters to use when you create the VM in the import process or the disk image won’t be able to run. It also doesn’t capture the state of the virtual machine.
Vbox has a very nice snapshot feature. If one could import / export snapshots it would be perfect.
