Hey guys.

Iv made a virtual machine using virtual box.
My OS is Ubuntu 10.10
And my virtual OS is Ubuntu server 11.10

After running my virtual machine for 10 mi it's I get errors and massive lag.

Iv given 15gig of my SSD hard drive to the virtual machine.
I'm sure I haven't used that!
700m OS
Maybe a gig or two of updates at most.
And a few minor dls

After being confused with errors on hardisk space,
Unchecked my vm.

Iv noticed a tab that says "virtual size and actual size"

Virtual says 15g and actual sais 4g

Can anyone explain what Iv done wrong.

Edit: my .vdi backup (replicate)
Is also 4g?
