Bug 341383 – sys-freebsd/boot0-7.2: can't boot gentoo/freebsd-7.2 inside virtualbox-ose-3.1.8

• Status: RESOLVED FIXED
• Product: Gentoo/Alt

[Description i.Dark_Templar 2010-10-16 20:17:24 UTC]

Using ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.3/FreeBSD-7.3-RELEASE-i386-livefs.iso as livecd and http://www.gentoo.org/doc/en/gentoo-freebsd.xml as guide, I'm installing gentoo/freebsd-7.2 inside virtualbox-ose-3.1.8. All installation goes fine. But then I can't boot gentoo/freebsd-7.2.

I'm getting next message:
can't work out which disk we are booting from
Guessed BIOS device 0xffffffff not found by probes, defaulting to disk0


Reproducible: Always

Steps to Reproduce:
1. Inside virtualbox-ose-3.1.8, using ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.3/FreeBSD-7.3-RELEASE-i386-livefs.iso as livecd and http://www.gentoo.org/doc/en/gentoo-freebsd.xml as guide, install gentoo/freebsd with portage profile x86/freebsd-7.2
2. install boot0 or grub (doesn't really matter) during step 1
3. boot into installed system

Actual Results:  
System doesn't boot, says
can't work out which disk we are booting from
Guessed BIOS device 0xffffffff not found by probes, defaulting to disk0

Expected Results:  
System should boot fine

I've tried both grub and boot0, but looks like it's issue with /boot/loader.
If I tell to boot /boot/kernel/kernel directly, first it says something like "loader(8) metadata is missing", then it asks about root partition, I type: "ufs:ad0s1a", then it boots fine, but when it comes to login prompt, keyword stops working. I think that's because "loader(8) metadata is missing".

By the way, host is gentoo/amd64 if this is relevant.

not "keyword", it's "keyboard", fix

[Comment 2 i.Dark_Templar 2010-10-16 21:36:01 UTC]

During experiments I found out that emerging sys-freebsd/boot0 with CFLAGS="-march=i686 -pipe" and CXXFLAGS="-march=i686 -pipe" solves problem.

Before that I used CFLAGS="-O2 -march=i686 -pipe" with same CXXFLAGS

So, "-O2", and probably other optimization flags should be filtered in this package.

Please, update ebuild and then close bug.

I confirm. After filter-flags I can boot g/fbsd-7.2.

Before filter-flags I can't boot g/fbsd-7 on real hardware and on qemu-kvn.

[Comment 6 Alexis Ballier 2013-08-27 20:22:54 UTC]

shouldnt be a problem with recent boot0 versions
