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.
(In reply to Mahmoud Al-Qudsi from comment #0) This happens in virtualization? Under which hypervisor?
(In reply to Allan Jude from comment #1) VMware ESXi 6.0, though I have no reason to suspect it's limited to that platform or indeed related to virtualization at all.
