Virtio-SCSI & Windows XP

[Jorge Fábregas]

Hi,

Do "Windows XP" guests work with the new virtio-scsi? Do we use the same
old virtio drivers during installation?

Thanks,
Jorge

virtio-scsi for WinXP doesn't exist, and it seems like
we are going to drop virtio-scsi for Win2K3 as well.

Thanks for confirming.  I just wanted to try out the discard='unmap'
option and, if it was available, I still had to investigate if there was
any command like fstrim for XP.

Back to virt-sparsify!  :)

Thanks.

When I get around to it, I'm going to change virt-sparsify to do
in-place sparsification, which *should* now be possible (at least with
some underlying disk image combinations).  This would work with any
Windows guest including XP since it'll be using a recent Linux kernel
+ recent virtio-scsi + ntfs-3g.
