If my root filesystem is btrfs on an SSD, will my Windows 7 Virtual Machine guest run better if I install it to a raw partition than if I install it to a file on the btrfs partition?
Host OS: Ubuntu 11.10 (Oneiric) amd64 desktop

I believe that it will be faster to run the VM from a raw partition after the SSD's blocks have all been written to, because TRIM commands from the guest OS will be passed through to the SSD, which would not be the case (AFAIK) if the VM were running from a file.
I've since written a blog post describing how to set up a Windows 7 guest running from a raw SSD partition under an Ubuntu 11.10 host.
