Fedora 16 now!

Release 16 aka Verne of Fedora Gnome 3.2.1

First lesson - how do I install Google Chrome via command line?
Answer: Followed instructions here
But before I finished the first lesson, I had to grapple with some questions, such as:
1. How do I go as root in the terminal? Answer:

su -

2. What editor can I use, as there is no nano installed? Answer: gedit
Got these answers from this source
Still as root, add the virtualbox repo to yum
[root@lave ~]# gedit /etc/yum.repos.d/virtualbox.repo
And now attempting to install Virtualbox -
su -

yum install dkms

Successfully installs the pre-requisite dkms package

Unlike in Ubuntu, installing dkms does not include the gcc package, so need to install that as well

yum install gcc

Then add the virtualbox repo to yum -
[root@lave ~]# gedit /etc/yum.repos.d/virtualbox.repo
The contents of the file from the virtualbox site here
Then download the rpm file for Fedora, and perform this as root as well:

yum install VirtualBox-4.1-4.1.6_74713_fedora16-1.i686.rpm

The complete virtualbox installation for Fedora I used can be found here.

Installing Gimp goes like this:

yum install gimp

And installing Flash is a bit more involved, but level of difficulty (or ease) is the same as Ubuntu's, in my opinion. The steps for installing Adobe Flash is here.

Virtualbox 4.0.12 in Lubuntu

Summary:
1. Modified a system file
2. Download, register a public key
3. Download virtualbox package for Ubuntu 11.04 (Natty)

Installing Virtualbox 4.0.12 on Lubuntu 11.04 (Natty)

1. Modified the sources.list file

sudo nano /etc/apt/sources.list

insert the following line

deb http://download.virtualbox.org/virtualbox/debian natty contrib

and save the modifications.
2. Download and register the Oracle public key

wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -

3. Run these:

sudo apt-get update
sudo apt-get install virtualbox-4.0

4. Download and install the Virtualbox extension pack
5. Add user login to the vboxusers group (under System Tools > Users and Groups)

virtualbox stuff

Version 4.x changes the game somewhat from version 3.x.

To enable USBs, you'd need to download a separate file called extensions pack. USB is NOT included in the vbox additions, as in earlier versions.
Download the extensions pack using your host browser, not the guest VM.

Then shut down your VM (if it's running), and install it under File-Preferences-Extensions.

Then, THEN, make sure your Linux user id belongs to the group vboxusers. System-Administration-Users and Groups, under Ubuntu's main menu.

Only then did my USB drive work inside the guest machine.

Import/Export appliance - it works. I exported from v3.1 (still under the Sun logo), to v4.0.2 (Oracle logo). Different machines. Installed ssh-server on the destination laptop, installed filezilla on the source laptop, did the export locally, then did a sftp to copy the 3 virtualbox files, then on the destination laptop, did the import.

The 3 files generated during export were:
1. *.mf
2. *.ovf
3. *.vmdk (the virtual hard disk)
