KVM, VM, Large disk and spinup

[biopixen]

Hi everyone.

Im thinking about using a VM (W2K-server) to host my smb-shares for my home network (about 7 devices). What would happen if i create a virtual disk2 on my system and mounting and sharing this disk on the vm. The RAW disk is 4TB and my disks (4disks á 4TB and a parity). Will the disks "share" the image/raw-disk or will one disk be allocated?
