We will need to use SCSI device so we can fully trace it in exercise 5. Xen hypervisor supports SCSI emulation, but only by emulating outdated LSI 53c895a controller which is not supported by Solaris. However, we can create iSCSI devices in Dom0 and supply them to virtual machines. The following guide is created for Debian 7 which uses iSCSI Enterprise Target. Recent Linux kernels replaced it with LIO stack.
