From 9143d5f0f14c1eef92a362b3b976606ad2874daa Mon Sep 17 00:00:00 2001 From: Gonglei Date: Thu, 29 Jan 2015 15:08:54 +0800 Subject: [PATCH] vhost-scsi: add a property for booting Because Qemu only accept an wwpn argument for vhost-scsi, we cannot assign a tpgt. That's say tpg is transparent for Qemu, Qemu doesn't know which tpg can boot, but vhost-scsi driver module doesn't know too for one assigned wwpn. At present, we assume that the first tpg can boot only, and add a boot_tpgt property that defaults to 0. Of course, people can pass a valid value by qemu command line.
