Bug #3175: DragonFly won't boot on GCE

* Author: tuxillo
* Status: Resolved
* Priority: Normal
* Assignee: 
* Category: Kernel
* Target version: master

DragonFly does not detect disks when running on GCE, the virtio-scsi controller is detected tho.

Here are there storage requirements that custom images need to fulfill [1]:

SCSI Storage Controller:
Virtio-SCSI Storage Controller
vendor = 0x1AF4 (Qumranet/Red Hat)
device id = 0x1004. Subsystem ID 0x8.
SCSI Primary Commands 4 and SCSI Block Commands 3 are supported
Only one request queue is supported
Persistent disks report 4 KiB physical sectors / 512 byte logical sectors
Only block devices (disks) are supported
The Hotplug / Events feature bit is supported

See attached dmesg with CAMDEBUG enabled and virtio debug set to level 5.
