windows 2008 no drives were found. click load drivers to load mass storage driver for installation

My server is a Oracle/Sun X3-2 or 4170. We have loaded Nimbula ( an IaaS platform) which uses KVM hypervisor in the server. Trying to load Win2K8 on top of KVM. Mounted Sun ZFS storage as NFS and the iso sits there.
