Description Mahmoud Al-Qudsi 2016-01-07 17:31:03 UTC 
Problem:

After installing FREEBSD-10.2-RELEASE with guided ZFS-on-root autoconfiguration in MBR mode, the system does not boot after setup. The bootloader is never executed, and the system hangs at a static (unblinking) _ after POST.

Expected results:

System boots normally.

Reproduction:

A clean install of 10.2-RELEASE, choosing guided ZFS-on-root during setup, selecting (the only) two disks for the stripe, and changing the mode away from GPT to MBR.

Testing environment:

A new virtual machine with two SAS disks selected during setup for the root vdev. 10.2-RELEASE amd64, booted from ISO image (disc1.iso).

Workaround:

If BIOS does not have a GPT disk bug, the exact, same configuration but keep the GPT option set will boot.

This happens in virtualization? Under which hypervisor?

VMware ESXi 6.0, though I have no reason to suspect it's limited to that platform or indeed related to virtualization at all.
