Setting up a Virtual Machine
 

I have CentOS 5.7. How would I go about setting up a virtual machine so
as to run another Linux distro on top of it? Specifically Scientific
Linux or Vinux, a special distro for blind users. I will be using the
latter to test my BrailelBlaster software with gtk and the Orca
screenreader. Will I have to assign memory to the VM permanently?

Thanks,
John

imho, the easiest way to do this would be to install VirtualBox. the
memory assigned to the VM is only in use when the VM is active, you can
'standby' a virtualbox and it releases all its resources, then resume it
at another time.

So I tried to install the latest version of VirtualBox from
virtualbox.org It turned out that it deleted a previous version, which I
suppose was provided with CentOS and then couldn't install itself. The
error lmessage said it could not find the kernel source. What should I
do now?

"yum install kernel-headers kernel-devel"
such software needs usually to compile kernel-modules

Do they match the version of your running kernel?

output of "uname -a" and "rpm -qa | grep kernel" would be helpful

+1,

this is best way to install Virtualbox and keep it updated. Just notice
that when 4.2.0 comes out, you will need to watch out for new release,
deinstall current version and install 4.2.0, since upgrade to minor
version is not supported. Updates to 4.1.x are via yum update.
