If your host operating system is rpm based linux, like SL, all you need is to add another repo :

cat /etc/yum.repos.d/virtualbox.repo 
[virtualbox]
name=RHEL/CentOS-$releasever / $basearch - VirtualBox
baseurl=http://download.virtualbox.org/virtualbox/rpm/rhel/$releasever/$basearch
enabled=1
gpgcheck=1
gpgkey=http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc

and then

sudo yum install VirtualBox-4.0

Cheers
Alex

In my experience trying to get vmware to load and run under SL6 has been nothing short of  a root canal.  All I needed was to load a OpenSolaris/Indiana quickly from a live medium, no install no mess. I shied away from VirtualBox due to the Oracle nature of the beast and tried to load vmware first. That was doomed to fail apparently. Instead a navigation to the virtualbox page, a download of an rpm and bam done.

Sorry this is kind off topic just an experience of one user.

On my MacBook Pro I have VirtualBox running SL 5.4, win xp and FreeBSD.
I also had another guest  OS -- OpenSolaris but Oracle killed that project :-(
On RHEL 5 I run VirtualBox with win XP and I am very happy with VirtualBox.

I respect your opinion about virtualbox Chris, but virtualbox best than
vmware?? Absolutely not. It's free, yes but is worst in most aspects
than vmware.

For example, under vmware you can run ANY operating system that runs on
i386 platforms with more performance than virtualbox (included
unsupported operated systems), with virtualbox not.

And about using USB passthrought and 3D support. I don't know which type
of problems do you have got with vmware, but I have a Windows 7
installed with this feautures and it is fast and simple to configure
under vmware.

Best regards.
