Problems and solution: Uninstalling VirtualBox old version

I had VirtualBox 3.2.8 installed on my system (Windows XP, i686). When I tried to install latest version 4.1.8, the installation sequence asked to uninstall version 3.2.8 and that required executable file of VirtualBox3.2.8.

Which I had deleted! 😦

Now, what to do?

  • I deleted VirtualBox folder from my program files directory.
  • Then, my friend Chetan suggested me to remove registry entries. Run “regedit” in ‘Start->Run’.
  • Now search(ctrl+F) for “virtualbox”; you would get many keys. The registry editor has two panes. Right side shows the key value and left side shows the containing location.
  • On the left pane, look out for folder that is in “open” icon (there would be only one folder looking different from others). Delete this folder.
  • Keep searching for the string by “F3” and keep deleting these folders.
  • You should get a message from Windows that registry scan finds no such word now.
  • Now, try installing VirtualBox. It worked for me 🙂

VMware player vs VirtualBox: which is better?

I have a Windows XP host machine with guest Ubuntu OS. I started with the latest VMWare player and benefits I noticed:

VMware

1. Hassle-free installation of Ubuntu (VMware provides “easy install” for Ubuntu)
2. Seamless integration between guest and host OS
o) You can copy-paste/ move files across host and guest!
o) Clipboard is shared bi-directionally

3. Very good performance: applications, network, and devices (DVD)
4. Display scales well with proper resolution on bigger screen with “VMWare tools”.
5. You can have multi-processor simulation (2 cores)

VirtualBox

1. Easy Ubuntu installation
2. Most horrible and pathetic clipboard sharing. Contrary to claimed, it provided one-way clipboard from guest to host.
3. XP clipboard stopped working and never worked till I stopped VirtualBox.
4. Supports VMDK files but it’s crappy, buggy and leaves VMDK in an un-usable state. I could never run my VMDK with VMWare later.
5. Can simulate up to 4 cores.
6. Supports shared folder between host and guest. I think it’s a generation behind what VMWare provides.
7. Very slow performance: application, system start-up/ shutdown or stand-by. This is the biggest letdown.

My verdict: VMware!

VirtualBox has miles to go and I am using VMware happily.

The best virtualization software: VirtualBox v/s VMPlayer

I was an avid user of VirtualBox and was pretty happy with it. It gave me freedom to experiment with different OS in a rather safe, transparent, and convenient way. So I used to keep Linux as host and Windows as guest. Performance was good and bugs were non-existent.

Then I found VMPlayer. It surprised me a lot with following reasons:

a) It supported ISO images for Ubuntu, my fav Linux disto.

b) Set up was easier/comparable to VirtualBox.

c) Unity mode: What a feature! A seamless integration of guest OS with host application. You don’t have to click the mouse, you never lose window focus. I can now browse through guest OS with Alt+Tab.

d) Very stable, good performance, and I am a happy customer.

e) The biggest benefit with VMPlayer is seamless file operations between host and guest. You can copy, move, delete files without any problem. VirtualBox still don’t have this feature (till Version 4+, May 2012).

f) Clipboard on VirtualBox is buggy and most of the times non-functional. VMPlayer has a reliable clipboard and you can freely move data between host and guest.
