No virtio I take it...
An install of XP does just as long for me too. Really painful.

No virtio, no speed up.

You just have to provide swap through the disk image you create for
Linux (translation: swap is going to kill you if you don't have virtio)
and Windows will of course be using a page file on the filesystem
created on the disk image you assign it. As for swap size, it has
nothing to do with how much memory you have. Is the LPI still spouting
that nonsense about swap must be equal to twice the RAM installed? So
long as you do not swap, you don't even need a swap partition. Gauge how
much memory you will use and then assign accordingly if it will chew
more than available RAM.

Just what do you think virtfs is?

Sure, but we can't hold your hand all the way. I sent you links on
virtio...maybe you want to read a bit on them so you do not take another
thousand hours to install your next guest operating system?
