BbOoOoTt: Parallel Dual Boot

On my laptop I have a work partition with a stable release and a test partition with a development release. Here I want to show you how I set it up to work with both of them at once, using VirtualBox.

The idea is that if virtualization enables you to run an additional machine on an additional (virtual) disk represented by an image file, it should also be able to operate on the actual disk and in this way convert dual booting from serialized to parallelized. And indeed VirtualBox can do it and the documentation is in its manual, chapters 9.9 "Using a raw host hard disk from a guest" and 9.9.2 "Access to individual physical hard disk partitions".


Caution: accessing one file system from two machines at once is a sure way to corrupt it and lose data. VB gives you some protection but you still have to be careful. One thing, you must not share a swap partition between the two systems. Also, make sure that you do not have the other system's partition mounted, especially as a "quickie" on /mnt.

Setting up

Change this according to your needs:
Give yourself access rights to the other system's partitions (LOGNAME is preset by bash):
sudo setfacl -m u:$LOGNAME:r $DISK
sudo setfacl -m u:$LOGNAME:rw $DISK$SWAP $DISK$ROOT
Copy the bootloader of the other system to a file:
dd if=$DISK$ROOT of=/tmp/boot.bin bs=512 count=1
Create a virtual disk to refer to the other system's partitions:
VBoxManage internalcommands createrawvmdk -register \
-filename ~/.VirtualBox/VDI/other-system.vmdk \
-rawdisk $DISK -partitions $SWAP,$ROOT \
-relative -mbr /tmp/boot.bin
That's quite a mouthful so let's go over the options:
  • register is a convenience setting that attaches the created disk to the VB disk manager.
  • filename is the virtual disk being created and it must be an absolute path.
  • rawdisk is the device of the whole target disk.
  • partitions restricts the access to these partitions. Other partitions will be visible but appear to contain only zeroes.
  • relative means that we will be able to drop access rights to the whole disk (see the next command) and retain only those to the used partitions
  • mbr specifies bootloader code to be used (partition info is still taken from the real MBR). That is important since in my case the real MBR references GRUB's menu.lst from sda1. That partition will appear as empty and GRUB would fail with "Error 17". So I give VB the boot record of the other system which references menu.lst on its own, visible, partition.
Then give up rights we no longer need:
sudo setfacl -x u:$LOGNAME $DISK
Now create a new machine in VB and attach the vmdk to it.
(there is a CLI way but I just clicked in the GUI)

Running it

Make sure that the other partitions are not used: (Hmm, VB should do that by itself. Must file a bug for that...)
sudo swapoff $DISK$SWAP
sudo umount $DISK$ROOT
Click Play and have a lot of fun.

If you used the defaults when partitioning, you will not get very far because the initrd will not find the disk. The bootloader refers to it by its ID but it is no longer /dev/disk/by-id/ata-TOSHIBA_MK8032GAX_Y6EAT0PKT-part6 but rather .../ata-VBOX_HARDDISK_VB22889591-0c34ac94-part6. The workaround is to edit the GRUB menu on the fly (ESC, Enter, (E)dit, ..., (B)oot) and to replace the long strings by the short names like /dev/hda6. The fix is to use paths from /dev/disk/by-uuid.

OpenStreetMap Diaries via a GeoRSS Box Filter

OpenStreetMap has this nice feed of its users' diaries, so that you can get all excited about the progress that fellow mappers have done near you. Now if you actually try to follow that feed, you may notice, as did I, that the problem is in the word near, which is the missing piece. It does not help to learn about new developments on another continent.
Fortunately (and unsurprisingly) the feed is GeoRSS so we can filter its contents based on the coordinates supplied with most diary entries. I did not find such service on the Web so I wrote it myself: a GeoRSS Box Filter. You say geofilter.php?url=...&minlat=...&maxlat=...&minlong=...&maxlong=... and it filters the given feed according to the given bounding box. If you omit the url, it defaults to the above mentioned OSM diary feed, and the bounding box defaults to Czechoslovakia.
More examples? How about the United Kingdom? or Georgia? (The Export tab is handy to get the numbers, BTW) To watch for uploaded GPS traces, use geofilter.php?url= I wonder what other interesting feeds you can find to experiment with (but I did not try anything else than RSS 2.0).
Oh, and I worked on this all on the company time because it's Hack Week3 now, yay!

cnetworkmanager 0.7.1

Cnetworkmanager is a command-line client for NetworkManager, intended to supplement and replace the GUI applets. So far it is a single python script. What is new in version 0.7.1:
  • it does not need a configuration file anymore:
    cnetworkmanager -C publicnet
    cnetworkmanager -C myessid --wep-hex 112234445566778899aabbccdd
    cnetworkmanager -C another --wpa-psk-hex \
  • it works with NM 0.6 (tested on Ubuntu 8.04 Hardy and a pre-release OLPC) in addition to the older support for NM 0.7pre (tested on openSUSE 11.0)
What is still left to do:
  • sooner:
    • specifying the key as a non-hex passphrase
    • reading the configuration stored by the GNOME nm-applet
    • possibility to quit after a connection is established
  • later:
    • more encryption schemes (WPA2?)
    • more connection types (dial-up, VPN)

Cultural Exchange 4: First YaST

Managed to compile and run YaST up to nfs-client and ntp-client. Of course it does not work properly, but makes for a nice Potemkin hamlet.

Fresh libzypp needs cmake 2.6 but there is only 2.4 in .debs. Fortunately the cmake authors provide a binary tarball with 2.6, only one has to know where to put the contained directories.

Notes for clean-up: Libzypp should say it needs hal-storage and boost-filesystem too. Python-bindings should check for python-dev, should use python-config. Perl does not seem to respect vendor_arch for

Cultural Exchange 3: First .deb

Started to build YaST. Managed to compile yast2-core. Now going to make it repeatable by properly packaging the dependencies. The first one is blocxx. Bleeding edge stuff is in the Build Service: home:mvidner:debian. The post How to make debian standard debs from scratch was much helpful.

Tried to print and failed miserably. The setup tool would not work with a remote CUPS printer, kept asking for my password. Switching AppArmor from enforcement to complain mode did not help, nor did disabling it.

The development package for openssl is libssl-dev (openSUSE: libopenssl-devel). helps with that.

Perl packages, named perl-Foo-Bar on openSUSE, are usually named libfoo-bar-perl on Debian.

Packaging system started to complain that packages cannot be verified.

(Cultural Exchange is my long term project of working with Ubuntu instead of openSUSE. TODO: make a permanent index page.)

YaST Workshop 2008

We had the annual YaST workshop last week. The people in the team boldly went to explore new APIs and one of the results is experimental integration of PolicyKit into YaST. If you really want to break your system, you can try the current code.

Cultural Exchange 2

Gnome would crash before the panel would show up. Also, the text console did not work (graphic artifacts instead). Failsafe Gnome did work, which does not have Compiz, so I took a hint to change the graphics driver. System / Management / Hardware drivers offered me to install the non-free xorg-driver-fglrx and now it works.

command-not-found is enabled out of the box and it rules. openSUSE should have it by default too.

rpm -ql foo
dpkg -L foo
rpm -qa "foo*bar"
dpkg -l "foo*bar" (and it also shows packages that are not installed)

Cultural Exchange: First Blood

I decided to expand my horizons and install Ubuntu on my main work computer. So today I offer you the first notes from my observations.

mutt somehow stopped tracking new mails. Fortunately :set check_mbox_size on works around that.

My subversion working copy from openSUSE was created with svn 1.5 but Hardy has only 1.4. So I manually got debs from the coming Intrepid release, and luckily 3 of them were enough: dpkg -i {subversion,libsvn1,libneon27-gnutls}*.deb from here and here.

LinDevDoc Got Tagging

Bluebear has improved LinDevDoc (original announcement) so that it can do tags now.

Addressing Lines in Plain Text Files

Jirka suggested a possibility to enhance YCP documentation with real-life code examples. For that, we'd need to point to numbered lines within the source code. I thought that ViewVC can do it but apparently not (maybe annotate has it, but it is broken at our site). But there is a new generic way: RFC 5147: URI Fragment Identifiers for the text/plain Media Type. Only none of the browsers seems to support it today...

This points to line 13, with the prototype of main:,13

Medoosa in OBS

Medoosa is a documentation tool for C++ that can produce UML class diagrams including generalizations and associations. Corrections can be made interactively in a diagram editor (Dia) and are fed back into the source as Javadoc-style comments. At this time, the layout must still be done by hand. Some code is already present to produce the layout with Graphviz.

I wrote it for my master's thesis at the Charles University back in 2001 and it has been since then quietly sitting at SourceForge. Today I have rebuilt it in the openSUSE Build Service: Medoosa, CcDoc-0.7a (required).

cnetworkmanager 0.4

I pulled together 0.4 yesterday:
  • New: changed license to GPLv2 or later, to match other parts of NM
  • New: distinguish WEP, WPA, WPA2 for -n.
  • New: -o, -w control online and WiFi status.
  • New: basic device info for NM 0.6
  • Fix: recognize Notification Messages in knetwormanagerrc.
  • Fix: -u: better error message when applet not running.
  • Fix: standardized option parsing, both -Cfoo and -C foo work.
The software is now hosted in a Git repository.

KNotify Client

Korshak asked how to do emerge -uND --world && knotify "Done!". I thougt it would be a piece of cake, but apparently not.
The short answer, zypper in libnotify; notify-send Done, has a disadvantage of requiring a fair amount of GNOME software. But it does use a proposed standard.
Then I find the method org.kde.KNotify.event, but its nice signature (ssavsayasx) means dbus-send (dbus-1-1.2.1-12) cannot invoke it (it cannot pass empty arrays, and it cannot wrap variants in arrays). No problem, let's use Python. But then we are blocked by knotify4 (kdebase4-runtime-4.0.4-19) reporting a wrong signature via the introspection interface.
# killall knotify4; cp /usr/bin/knotify4{,.bak}
# sed 's/type="a(ss)"/ type = "av"/g' /usr/bin/knotify4.bak > /usr/bin/knotify4
Now which event should we use so that the user actually sees the message? There are many of them, with user configurable actions. warning/kde seems to work out of the box.
#! /usr/bin/python
import sys
import dbus
m = sys.argv[1]
kn = dbus.SessionBus().get_object("org.kde.knotify", "/Notify")
i = kn.event("warning", "kde", [], m, [0,0,0,0], [], 0,
That did it. But I still hope that there is a simple solution for KDE4 that I have missed.

D-Bus Spy

Like dbus-monitor, it monitors the system or session bus. Additionally, it can write the traffic to a file and read it later (-w, -r). It can dump all the gory details (-d) or pretty print all the gory details (-p). Like DBusMessageBox which inspired it, it can make message sequence charts (-c). It has some simple filtering abilities (-f, -F).

Try 0.1 if that sounds interesting.

try cnetworkmanager 0.3

cnetworkmanager is a command line interface for Network Manager. It is still lacking many features but I decided to announce it now, when it can:

  1. connect to WiFi networks
  2. read the configuration file of KNetworkManager

It is working for me on RC1 of openSUSE-11.0, which has NetworkManager-0.7.0.r3685-3. It is my first project in Python, so the code is somewhat cumbersome. Thanks to Mišo for getting me started (idea.o.o,, and Bille for the API docs.

Regarding related projects, I have seen network-manager-cli, but it is for 0.6 only and the developers were only active last August, so I decided that I should first write some working code for 0.7.

I am interested in comments, bugs, feature requests, patches, any feedback.

Here are some screenshots ;-)

Installation without YaST

With 96MB of RAM, Linuxrc will not start on 11.0 (RC1). So I decided to exploit the image based installation, and not to use YaST at all for a change.

The target machine has dual boot and I am logged on the other system via the network, so I could paste this all in. Fasten your hats...

Update: Planet SUSE is eating the dollar variables :-( See the original post at Blogspot for the real thing.

Target partition:
# mkfs.ext3 /dev/hda1
# mount /dev/hda1 /mnt

A flash drive with images and kernel:
# mount /dev/sda1 /media
# cd /media/misc

Note I used unlzma beforehand because the target machine is way slow for that
# du -m *
5 base-i386.tar
12 base-meta-i386.tar
527 common-base-i386.tar
22 kernel-default-

# for i in *.tar; do dd if=$i bs=1M | tar -C /mnt -xf -; done &

While it is running, watch the progress:
# pkill -USR1 -x dd
552202240 bytes (552 MB) copied, 709,291 s, 779 kB/s

# cp kernel-default-*.i586.rpm /mnt/tmp

Before installing the kernel, we must do some setup so that the post-install script works.

# for i in dev proc sys; do mount --bind /$i /mnt/$i; done

# chroot /mnt
Now I use ## to mark that we are chrooted in the target system.

Modify partitions as needed.
Also see ls -l /dev/disk/by-id
## ROOT=/dev/hda1
## SWAP=/dev/hda4
## cat <<EOF > /etc/fstab
$ROOT / ext3 acl,user_xattr 1 1
$SWAP swap swap defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0

You probably don't need to set this one and the others starting with FIX_

## FIX_BOOT=acpi=force
## GROOT="(hd0,0)"
## cat <<EOF > /boot/grub/menu.lst

setup --stage2=/boot/grub/stage2 $GDEST $GROOT

## sysconfig() { sed -i -s "/^$2=/s/=\"/=\"$3/" /etc/sysconfig/$1; }

I also need this. You probably don't
## FIX_MODS="ide-generic ide-core"
## sysconfig kernel INITRD_MODULES "$FIX_MODS"

I don't know whether these 2 are strictly necessary
## sysconfig bootloader LOADER_TYPE grub
## sysconfig bootloader LOADER_LOCATION boot

## rpm -Uhv /tmp/kernel-default-*.rpm
It will get the resume device wrong (according to *current* swap partition), but it seems harmless.

## grub-install

## passwd
## chkconfig SuSEfirewall2_init on
## chkconfig SuSEfirewall2_setup on

## exit
# reboot

BTW, I am fed up with the Blogger editor. Can I use an offline one so that I don't have to change blog hosting?

YaST from the Command Line

The Automatic Configuration in openSUSE 11.0 installation is good because you don't have to click Next so much, but now I am missing the button for opening SSH in the firewall.
Here's a one-liner to do it using YaST:
# yast2 firewall services add zone=EXT service=service:sshd
Try also:
# yast2 firewall help
# yast2 firewall longhelp
# yast2 firewall summary
# yast2 firewall services list
# yast2 -l
# yast2 FOO help
(Saying "yast" instead of "yast2" should work too, but there is bug 374259.)

D-Bus Spying

I found how to make dbus-monitor show me more than just signals on the system bus. The documentation in dbus-daemon(1) is very terse about that. This is probably insecure, although I don't know of an interesting exploit.

D-Bus Sightseeing

I figured it was time to learn more about D-Bus. Today, let me share some useful calls that I found so far. Hopefully they will inspire you to experimenting too and together we will have a chance of learning more.
$ dbus-send --print-reply \
--dest=org.kde.klipper \
/klipper \
method return sender=:1.37 -> dest=:1.73 reply_serial=2
string "Hello D-Bus"

Your result will be probably different. In fact, I spent several minutes wondering why the method does not return anything and just repeats its name ;-)
The meaning of the parameters: --dest is the destination connection; apparently D-Bus cannot find it out from the following parameter: /klipper: the destination object. org.kde.klipper.klipper is the interface. Most objects have their own interface plus the introspection interface org.freedesktop.DBus.Introspectable. getClipboardContents is of course the method name.

For further exploration, the GUI tool qdbusviewer is very useful. Try it for calling getClipboardContents now.
$ dbus-send --type=method_call --dest=org.kde.kwin \
/KWin org.kde.KWin.nextDesktop
$ dbus-send --type=method_call --dest=org.kde.kwin \
/KWin org.kde.KWin.previousDesktop
$ dbus-send --type=method_call --dest=org.kde.plasma \
/App org.kde.plasma.App.toggleDashboard
The type option is necessary because dbus-call defaults to type=signal which would not work. (BTW does anyone have a nice example for demonstrating a signal?) With print-reply in the first example, type=method_call is implied.

Let's pass some arguments:
$ dbus-send --type=method_call --dest=org.kde.klipper \
/klipper org.kde.klipper.klipper.setClipboardContents \
string:'Test Beta2!'
$ dbus-send --type=method_call --dest=org.kde.krunner \
/Interface org.kde.krunner.Interface.display \
So far we have been using the session bus. The system-wide bus offers even more fun:
$ dbus-send --system --print-reply \
--dest=org.freedesktop.NetworkManagerSystemSettings \
/org/freedesktop/NetworkManagerSettings \

array [
object path "/org/freedesktop/NetworkManagerSettings/0"
object path "/org/freedesktop/NetworkManagerSettings/1"
object path "/org/freedesktop/NetworkManagerSettings/2"

$ dbus-send --system --print-reply \
--dest=org.freedesktop.NetworkManagerSystemSettings \
/org/freedesktop/NetworkManagerSettings/1 \

array [
dict entry(
string "802-11-wireless"
array [
dict entry(
string "ssid"
variant array [
byte 102

byte 103
byte 115
dict entry(
string "security"
variant string "802-11-wireless-security"
/* more data. BTW you can't see any of this in qdbusviewer. */
(Interesting, every even call to NMS fails with a timeout)

Finally, a long list to scroll up while the music plays:
$ dbus-send --system --print-reply \
--dest=org.freedesktop.Hal \
/org/freedesktop/Hal/Manager \

TWM is the ancient window manager that you can use when troubleshooting the problems with X. It has always annoyed me that it can't make up its own mind and you have to place the windows manually when they first appear.

openSUSE 11.0 Beta 1: Is that the murderer's name and address in the victim's hand?

As Beta 1 is getting mirrored, I am excited to tell you about obscure parts of the installation that I hope you will never see.

YaST does not crash. Never. Well, only rarely. Especially not during the initial installation. Seldom. So what do we do when it does? We want the backtrace and the debugging logs. So before 11.0 we would ask you to please let it crash again, but with some special options to produce the backtrace and the debugging info. Spoils the fun.

Since Alpha 2 YaST will take care of the backtrace. Since Beta 1, it will also produce tons of the debugging messages, but throw most of them away and only show the last few of them in case of a crash. Reporting a bug has become much easier!

This has actually helped us already in debugging one crash that blocked the release of Beta 1, bug 380283. If you want to see for yourself, search the log for "got signal". The next line says "Liberating suppressed debugging messages" and afterwards there is "Back trace".
