Using Xen With LVM-Based VMs Instead Of Image-Based VMs (Debian Etch) This guide explains how you can set up LVM-based virtual machines on a Xen host running on Debian Etch instead of virtual machines that use disk images. Virtual machines that use disk images are very slow and heavy on disk IO.

You say that "Virtual machines that use disk images are very slow and heavy on disk IO". Do you have timing and measure to back such statements? It is I don't know, but I suppose that the difference couldn't be so big if you use a filesystem like ocfs2 (it was made for big database files) and because b.e. the performances of a swap file since 2.6 kernel aren't so different from such of a swap partition.

I was wondering if I can apply the same concept to my VirtualBox installation.  Should try anytime soon.
