We don't have single SCSI, network, etc driver handling every devices in their respective class, I don't see why it would be different here. A hypervisor presents the same interface to the guest OS (whether it is Linux, Solaris or another OS) much like a piece of silicone does and it may very well be different form other hypervisors. -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
