Changing over effortless to 64bits from 32 bits

[comedit]

I have in ignorance installed the wrong type of kubuntu. I should have installed the 64 bit version instead of the 32bit version to be able to fully utilize my 4gb memory for virtualization.

I am already using it for a few months and really want to avoid spending a whole day or more reinstalling everything.

I have a laptop with kubuntu 8.04 installed (just upgraded).

I have an e-sata conection available and an empty external harddisk with more then enough free space.

My question Is there an easy way of doing this or do I have to go don the route of reinstalling everything ?

What kind of virtualization are you going to use? Xen? OpenVZ? Both come with 32bit kernels that support more than 2GB of RAM.

Falko thanks for the info.

But I will probably want to be able to run more types (vmware, virtualbox, and openvz.) for comparisson reasons.

However your tip is very usefull.

I assume if I would want to go change anyway it would be a complete
reinstall and thereis no simple trick ?

You'll have difficulties finding a kernel that supports Xen and OpenVZ at the same time, unless you compile it yourself.

To be honest, I can't tell if VMware supports more than 2GB RAM on 32bit systems...

Ok I will check the vmware sites for specs

The extra gb is to support more machines running at the same

Thanks for the info
