Re: [PATCH] VirtualBox headless VNC support by LibVNCServer

[Daisuke Aoyama]

Hi, all

I updated for 3.1.2_1 and fixed bug of initial pixel format.

Before building, install "ports/net/libvncserver".
I recommend you backup virtualbox-ose directory before doing.
Uncheck QT4, X11, NLS by make config before extracting.

Howto apply the patch:
# cd /usr/ports/emulators/virtualbox-ose
# make config
# make extract
# patch -p < /path/to/VBox-VNC-Makefile.patch
# patch -p < /path/to/VBox-VNC-20100127.patch

Ah, I forgot that using nfsm_aligned() causes nfs_realign() to
be a NOP on architectures without strict alignment requirements
for performance reasons. That's generally fine but unfortunately
that way you don't actually exercise the code which caused the
problem before (unfortunately I still don't manage to hit the
unaligned case myself).
Could you please test with #ifdef __NO_STRICT_ALIGNMENT replaced
with #if 0 in sys/nfs/nfs_common.h? The vfs.nfs.realign_count
counter should also increase then.

I put VBox-VNC-20100127.patch in files an modified the paths to be 
acceptable to the ports tree and applied the Makefile patch and it 
works well. (I say this as IMO it's easier to try if you distribute it 
like that :)

Is there any prospect of being able to build the VNC server extension in 
parallel with X11/QT4?

booting off GPT partitions

[Dan Naumov]

Hey

I was under the impression that everyone and their dog is using GPT
partitioning in FreeBSD these days, including for boot drives and that
I was just being unlucky with my current NAS motherboard (Intel
D945GCLF2) having supposedly shaky support for GPT boot. But right now
I am having an email exchange with Supermicro support (whom I
contacted since I am pondering their X7SPA-H board for a new system),
who are telling me that booting off GPT requires UEFI BIOS, which is
supposedly a very new thing and that for example NONE of their current
motherboards have support for this.

Am I misunderstanding something or is the Supermicro support tech misguided?

For what it's worth, I've never encountered any production x86 system that
I've worked on (Linux, FreeBSD, Solaris 10, or OpenSolaris) which has
used GPT.

I don't know who's giving you the impression that "everyone and their
dog is using GPT".  Why is this feature a deal-breaker for you?  Why are
you giving it so much attention?

The Dell T3500 I just configured was announced in March 2009 IIRC and it is 
booting off GPT just fine.  Didn't do anything special for that.  Then again, I 
do not see non GPT support as a deal breaker (even for ZFS).

Re: booting off GPT partitions

[Vincent Hoffman]

GPT booting is I believe only natively supported using an EFI BIOS.
However if you wish to use GPT booting with FreeBSD its not too hard,
you just cant install using sysinstall.
The Examples section of the gpart manpage is what i used to configure
the disk for my home server, a zotac ion atom based board  (dont have
any production servers at work using it at the moment.) Then i just
installed using the files on the usb image.

>From what I understand gpart installs the pmbr file as a basic bootstrap
in the protective MBR present in the GPT partition scheme, this is
bootable by a standard bios and is able to understand enough GPT to look
for a freebsd boot partition, load the bootcode in that, which loads the
kernel etc.

So no they arent completely misguided, but its certainly possible to use
a GPT scheme without an EFI BIOS.
What I would like is an efi bootloader for i386 so I can get my
powerbook to run FreeBSD again as it has got an efi bios and bootcamp
wont boot freebsd for me at the moment :(

The compatability MBR should be sufficent to let a non-GPT aware BIOS
boot from GPT.  Once you've loaded code from the boot partition, the
BIOS doesn't need to know anything about the partitions.

Perhaps both :-)
It depends on what booting capabilities you need from your BIOS.
With FreeBSD we currently typically don't use "pure" GPT and use Protective MBR
and install real boot code into a special boot partition.  Protective MBR looks
like a "normal" MBR to BIOS, and boot code in Protective MBR is smart to find 
the
boot partition and hand off boot process to code in it.
This way you can almost have the best of both worlds, but with some limitations
(like multibooting).  I don't know what other OSes do or expect in this area.

well, I'm having some issues during the 8.0-stable bootup process.
it takes ~9min to finish the entire boot process to shows me the

since my first installation attempt to get freebsd up and running here
with my dv3-2155mx[1] hp pavilion laptop using 8.0-RC1 amd64 iso I
could not boot freebsd up smooth and nicely as it always did for me in
my last laptop (dv6130us)[2], but I could install it without any
problem.
you may check http://www.youtube.com/watch?v=gqtz7E7u4fA to see what
realy happens.

now I'm using a grub 0.97 from my old gentoo linux installation to
bootstrap the freebsd loader.
I tryed debug and verbose options using grub and freebsd loader.conf
but both just result nothing special.

I've been updated and downgraded my laptop bios (by Insyde Software /
HP) but got no good results either. I tryed versions F1.3A, F1.2, F0.7
and the original F0.6 version that came originally from HP.

to try another way to get into 8.0-stable or 9-current I used 7.2,
7.1, 6.4 and 6.2 release x86 and amd64 iso images to install freebsd
and an it's older btx loader but, unfortunately, got the same. it
always "freezes" ~9min.

I can use freebsd after all the bootup process with no problem.
It's a 8.0-stable amd64 now. but I realy wanna know how could I solve
this issue.

read some cases/PRs/issues with other hp laptops but nothing like this
one I have. one of the problems I read was about dv6000 series -
weird, it was my old laptop serie and everything was just fine
installing, booting and running freebsd into.

what you guys think about it? can you give me a hand or a glue to pass
this through?

thanks.

Are you using zfsloader? A month or so ago the ZFS code was updated to probe
all 128 possible GPT partitions instead of just four, resulting in a
slow-down, but probably not nine minutes' worth.

Re: immense delayed write to file system (ZFS and UFS2), performance issues

[Tommi Lätti]

Seems that the performance is indeed atrocious. I recently (like 2
days ago) had to rescue my zfs pool under opensolaris to spare disks.
The performance under OpenSol was what I was expecting, 70MB/s reading
and writing at the same time.

Now that I'm restoring the stuff back under FreeBSD 8.0-p2 it seems
that first the array reads from the source disk and then stops reading
and decides to empty the buffer to the destination. There's usually a
2 second pause and after that it goes back to reading. There seems to
be something really wrong with this, fbsd zfs implementation seems to
be unable to move data between 2 zfs pools writing and reading
simultaneously...

I think I'll just boot back to opensol and do the transfers there.

GPT was defined along with EFI, so many folks assume that you have to use EFI
to boot a GPT-labelled disk.  However, FreeBSD has its own BIOS-based 
bootstrap that can handle GPT-labelled disks.  I doubt the SuperMicro tech is 
familiar with that case.  I thought I heard that some folks had added GPT 
support to grub as well.

ZFS pool upgrade to v14 broke ZFS booting

[Paul Mather]

I have a FreeBSD guest running under VirtualBox 3.1.2 on Mac OS X.  It's 
running a recent 8-STABLE and is a ZFS-only install booting via gptzfsboot.  I 
use this VirtualBox guest as a test install.

A day or so ago I noticed "zpool status" report that my pool could be upgraded 
from v13 to v14.  I did this, via "zfs upgrade -a".

Today, when attempting to fire up this FreeBSD guest in VirtualBox I get this 
on the console:

=
ZFS: unsupported ZFS version 14 (should be 13)
No ZFS pools located, can't boot
_
=

and the boot halts at that point.  I don't see the boot menu I normally see 
that lists the opportunity to boot single-user; disable ACPI; and so on.

Has anyone else experienced this?  Is this a mismatch between gptzfsboot and my 
current pool version?  (Gptzfsboot includes the message I'm seeing.)  Am I 
supposed to rebuild and replace gptzfsboot every time the pool version is 
updated?  (There was no advisory in /usr/src/UPDATING concerning this, nor do I 
remember seeing it elsewhere.)

Now I have to figure out how to dig out from this.  Well, I guess that's what 
test installations are for... :-)

Cheers,

Yes, you're running a version of gptzfsboot that only knows how to run
version 13 and below. The commit that brought in version 14 support also
bumped the version number for gptzfsboot though it doesn't look like any of
the code changed; perhaps version 14 doesn't change anything that gptzfsboot
cares about. Try rebuilding and reinstalling gptzfsboot and zfsloader to see
if that helps:

cd /sys/boot
make cleandir
make cleandir
make obj
make depend
make all
make install
gpart bootcode -p /boot/gptzfsboot -i 1 /dev/somedisk

Of course adjust the gpart command for your setup.

There is no on-disk format change that affects ZFS boot itself, but you
will need to install new gptzfsboot.  If you have another system and
have the file, you can do it by booting from the LiveFS Disc, fetch it
from network, and use gpart to install it.

However, this won't boot disks larger than 2TiB, right?  At least not

Turning off APM seems to be the LINUX world's solution to this and other
similar problems. I got the impression that Windows also does this.

You won't be able to boot from a partition more than 2TiB in, but you
should still be able to boot as long as you boot from the front part of
the disk.

Since this is so fatal, you might want to give them the option to
continue here.  I suspect that zpool format changes that truly break
the boot loader (which is read-only at any rate) are uncommon where
the chances of ending up in this situation (with an unbootable
machine) are much more common.

Some time ago i had the same problem. I think it is good idea to add a note 
about
updating gptzfsboot in src/UPDATING.

Try GRUB4DOS. I use this so on boxes where I have Windows installed, I 
can keep GRUB in the NTFS partition.


I haven't seen this issue and am tracking -STABLE on an ASUS V-series
