This post refers to pre-release software for Hyper-V, formerly known as Windows Server virtualization. However, there is no difference in the guidance provided in this post.

In most cases SCSI Controller is the better option. When YOU use IDE Controllers?</p> <p>Tks,</p> <p>Carlos</p>http://blogs.technet.com/jhoward/archive/2007/10/04/boot-from-scsi-in-virtual-server-vs-boot-from-ide-in-windows-server-virtualization.aspx#3263509Mon, 13 Jul 2009 22:03:10 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3263509jhoward<p>Carlos - you have no choice but to use the IDE controller in Hyper-V as it's not possible to boot from a VHD connected to a SCSI drive in a VM configuration.</p> <p>Thanks,</p> <p>John. </p>
