Hi hopefully someone can give me a tip or a better google search query to run.

Talking to a guy that has a vmware server setup with 20 guests, all
xp. He set them up with a 10gig os drive (c) and a separate 5gig disk
image (d) that he configured a 3500-5000 swap.

Now my take on this is that since all the disks are on the same
physical disk anyway, should we just configured a single 15gig disk
image, configure a 5000-5000 (min/max in windows) swap file for
windows and be the same?

He was saying he thought it was better for performance because
otherwise the swap fragments the C:\ drive. He *claims* to have tried
this and saw a difference.

We plan on moving him from this vmware box with a single physical disk
to xen with a 4 drive raid. I really dont want to screw with 2 or 3 or
x disk images per virtual machine, management, backups etc. I told him
i would like to just give him a single 10+swap+extra = say 20gig
single disk image file to use.

Comments, input please?
