Olive reloaded or how to emulate Juniper routers

Installation

Requirements

JunOS runs on top of FreeBSD. So you need to download the mini installation ISO, version >= 4.5 because

earlier versions dont support the Intel e1000 interface (em driver). Personally, I used the FreeBSD 4.11

mini-inst ISO but you could use FreeBSD 6 or 7.

JunOS itself. If you are smart and patient you will find it. I used jinstall-8.5R1.14-domestic-signed.tgz for my

installations.

Qemu source code. Again, I used Qemu 0.11.0. You can choose to download it later with wget (Ill show you

how).

Download OpenVPN to create TAP interfaces (Windows only, optional).

More stuff whether you compile Qemu on Mac OS X, Windows or Linux.

Qemu compilation and patching on Mac OS X

The following procedure has been tested on Mac OS X Snow Leopard.

First you have to install the MacPorts [http://www.macports.org/install.php] and its dependencies (e.g. latest

Apples Xcode Developer Tools).

Open a terminal window and install zlib, wget and libpcap via the MacPorts:

sudo port install zlib wget libpcap

Unzip qemu somewhere (e.g. in Documents/JunOS). Then from the qemu directory, patch and compile qemu:

Because FreeBSD hanged a few times when I was installing it inside Qemu, I applied a patch (qemu-0.11.0-macosx)

which apparently xed the problem (this is totally optional, maybe you wont have any issue if not applied).

wget http://download.savannah.gnu.org/releases/qemu/qemu-0.11.0.tar.gz

tar xvzf qemu-0.11.0.tar.gz

cd qemu-0.11.0

wget http://downloads.sourceforge.net/gns-3/qemu-0.11.0-macosx.patch?download

patch -p1 -i qemu-0.11.0-macosx.patch

wget http://downloads.sourceforge.net/gns-3/qemu-0.11.0-olive.patch?download

patch -p1 -i qemu-0.11.0-olive.patch

./configure --disable-aio --disable-kvm --disable-kqemu --disable-sdl \

--target-list=i386-softmmu

make

sudo make install

Qemu compilation and patching on Windows

If you do not want to compile Qemu on Windows (I can understand that I provide a static version that you can

download here [http://downloads.sourceforge.net/gns-3/qemu-0.11.0.patched.win32.zip?download] .

First some dependencies must be installed, I chose to almost compile everything:

Download MinGW and install it (choose custom installation with g++ and make included). The file I downloaded

was MinGW-5.1.6.exe

Download MSYS and install it, answer yes to post-installation questions and put the correct path to MinGW

directory (should be C:\MinGW). The file I downloaded was MSYS-1.0.11.exe.

Download , zlib, SDL, MSYS coreutils into your MSYS home directory (e.g. c:\Msys\public\username). I

downloaded zlib-1.2.3.tar.gz, SDL-1.2.14.tar.gz and coreutils-5.97-MSYS-1.0.11-snapshot.tar.bz2. MSYS

coreutils is necessary because Qemu signrom.sh uses tools such as dd, od, expr, cp and printf which are

included in coreutils.

Download and install Winpcap Developer Pack: extract the contents of \lib and \include folders into \lib and

\include folders of your MinGW installation location (should be C:\MinGW\lib and C:\MinGW\include)

Start MSYS.

Compile and install zlib:

cd

tar -xzvf zlib-1.2.3.tar.gz

cd zlib-1.2.3

./configure --prefix=/mingw

make

make install

Compile and install SDL

tar -xzvf SDL-1.2.14.tar.gz

cd SDL-1.2.14

./configure --prefix=/mingw

make

make install

Install coreutils

tar -xvjf coreutils-5.97-MSYS-1.0.11-snapshot.tar.bz2

Copy the content of coreutils-5.97-MSYS-1.0.11-snapshot in the MinGW directory (e.g. C:\MinGW). You can also

compile and install wget [http://sourceforge.net/projects/mingw/files/MinGW%20Utilities/wget/wget-1.9.1.tar.gz

/download] in MSYS or simply use your preferred browser to download Qemu and the patch in the correct

directories.


tar -xvzf qemu-0.11.0.tar.gz

cd qemu-0.11.0



./configure --target-list=i386-softmmu

make

make install

Qemu compilation and patching on Linux

Compiling Qemu on Linux (Ubuntu) is quite simple.

First install the dependencies: ncurses, zlib, libpcap-dev and SDL libraries. SDL is optional, you can still use

Qemu in a console with the ncurses option. Then apply the patch and compile Qemu.

sudo apt-get install libncurses5-dev zlib1g-dev libsdl-dev libpcap-dev


tar xvzf qemu-0.11.0.tar.gz

cd qemu-0.11.0



./configure --target-list=i386-softmmu

make

sudo make install

Qemu acceleration

Qemu provides some ways to speed up the emulation, Ill talk about 2 of them: Kqemu and KVM. Kqemu can be

used on both Windows and Linux. KVM is only for Linux. I do not know if something exists for Mac OS X.

For more details about Kqemu, please have a look at the documentation [http://www.qemu.org/kqemu-doc.html]

. For KVM, see the website [http://www.linux-kvm.org/] .

The installation of Kqemu on Windows is relatively easy:

Download Kqemu.1.

Unzip it.2.

Locate kqemu.inf and install it (right-click and select Install). In Windows Vista, install Kqemu using the CMD

prompt and this command: rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 kqemu.inf

3.

Start Kqemu from the CMD prompt: net start kqemu4.

Kqemu on Linux (Ubuntu):

Install kqemu with: sudo apt-get install kqemu-source1.

If you do not want to use sudo each time you start Qemu, give the permissions to /dev/qemu with the

following command: sudo chmod o+rw /dev/kqemu

2.

For manual installation or other Linux distributions, please see the documentation [http://www.qemu.org

/kqemu-doc.html] .

KVM on Linux:

Qemu requires your kernel version to be >= 2.6.29 to enable the KVM support. You have to ensure this is ok

before you compile Qemu.

Dont forget to add the -kernel-kqemu or -enable-kvm command line options when starting Qemu (I didnt do it

in this tutorial). I would recommend to activate Kqemu only when you have your Olive image ready and

working.

Ive followed all the instruction but after qemu -m 256 -hda olive-base.img -boot c -localtime -nographic -serial stdio, nothing

happen. No qemu window appear and I only can see stderr and stdout les in the Qemu folder.

stderr notepad shows:

qemu: could not open serial device mon:stdio

stdout notepad shows:

Unable to open driver: stdio

Im trying to install olive in WinXP SP3 with qemu-0.11.0.patched.win32.

did anyone have the same problem as me?

Hi,

I always encounter this error (ELF Binary Type 0 Not Known). Do I missed something?

Thanks

Everything went smoothly following the directions exactly a written, till I actually got to pkg_add.

The VM complained about not enough space, saying I needed to change PKG_TMPDIR to a location that had at least 905682568

bytes. I cleaned out les I dont need any more and made sure PKG_TMPDIR was pointing to /var/tmp. After clening out the les I

had 1060060 K bytes free. So that should be enough. But kept getting same error.

O tried to run scp [email protected]:~/Desktop/jinstall-8.5R1.14-domestic-signed.tgz /var/tmp command but request gets timed out.

I put my PCs hostname instead of user, even i tried with the user i logged in with in my pc but still the request is getting timed out

ssh: connect to host 10.0.2.2 port 22: Operation time out

I wasted my 3 days to resolved this dont know y its not working.

I had put only qemu -m 256 -hda olive-base.img -boot c -localtime command when booting olive image cause when i put qemu -m

256 -hda olive-base.img -boot c -localtime \

-net nic,macaddr=00:aa:00:60:01:01,model=e1000 -net user the qemu doesn start.

Please help guys

hi while trying to upload Junos iam getting following error.

scp [email protected]:xxxxx\jinstall \var\tmp

ssh: connect to host 10.0.2.2 port 22: Operation timed out.

I thought my antivirus firewall might be blocking the udp and tcp packets so disabled that and tried .. then also i was unsuccessful

pl help here.

FTR, the pcap check in the patch is wrong.

Compiler barfs at not caster int return and also,

the $TMPC should be abefore the $LIBPCAP for the test compile to work.

Does anyone running this on a MAC OS X 10.6 know the replacement option for -cdrom in the QEMU command:

qemu -m 256 -hda olive-base.img -cdrom 4.11-RELEASE-i386-miniinst.iso \ -boot d -localtime

/Volumes doesnt work. Using the mount point doesnt work. I had this working on 10.5, but remember -cdrom didnt work.

Any help is appreciated!

Thanks!

Hi, Ive installed the olive by following the above procedure. However Im facing currently two problems.

1. I configure the Juniper Router in GNS3 and commit changes bye using commit command. But it does not take effect. until unless I

reload all the routers.

2. Im unable to find serial interfaces, ATM interfaces & Sonet interfaces.

Can Anyone provide me the help regarding this.

Im not able to proceed with the following command:

qemu R1.img -m 96 -nographic -daemonize -serial telnet::2001,server,nowait \

-localtime -net nic,macaddr=00:aa:00:60:01:01,model=e1000 -net user

telnet localhost 2001

It produces a stderr.txt file containing:

qemu: invalid option `-daemonize`

If I remove this option, it produces another error:

qemu: could not open monitor device `stdio`

Anyone else having this same issue?

Hi to all,

Ive tried to emulate JUNOS in GNS3 without success.

When I use the command qemu -m 256 -hda olive-base.img -boot c -localtime \ -net nic -net tap,ifname=tap0 -net

nic,macaddr=00:aa:00:60:01:01,model=e1000 -net user (in Ubuntu 10.04) and after creating the tap interface with tunctl, I get the

following message:

cant add tap0 to bridge wlan0: operation not supported

Ive tried to do it using the eth0 interface instead of wlan0, but I got the same results.

can anyone tell me whats wrong??

Thanks!!

July 19, 2011 at 06:29

josem

hi,

once olive is loaded, I configure an ip address for the en0 interface and do a commit but the check-out fails with this message:

vci/vpi/allow-any-vci is required

how is this possible if my interface is en0?
