Direct iSCSI Connectivity Within Guest OS
To successfully create direct iSCSI connections within the guest OS, the
guest OS must:
• Support an iSCSI software initiator.
• Be supported by the storage device.
• Have the required storage device specific drivers and software installed.
Setup and configuration of the iSCSI connection within the guest OS is the
same as that for a physical server running the same OS. Refer to the storage
device documentation for setup and configuration information.

iSCSI Connections from Both the Parent Partition and Guest OS
Because Hyper-V does not support Boot from iSCSI SAN (BFi) for VMs,
iSCSI direct connections only apply to data volumes. To host all the files of a
VM on iSCSI LUNs, you will need to have iSCSI connections from both the
parent (to host the VMs boot disk) and guest OS (to host the VMs data
disks). Using a combination of connections provides a great deal of flexibility
for configuring iSCSI connections to meet each VM's storage needs.
