Hi

I have seem to fixed this issues that was reported.

Here is how to install qemu on 10.6

Prerequisites is to have apple xcode installed on your machine please download this from apple https://developer.apple.com/technologies/tools/

There are many instructions around but just follow

http://blog.gns3.net/2009/10/olive-juniper/2/ under Qemu compilation and patching on Mac OS X

when you get to this point and downloaded the macosx.patch

wget http://downloads.sourceforge.net/gns-3/ ... h?download

then do

- go to the qemu-0.11.0 folder and rename the qemu-0.11.0-macosx.patch?download to qemu-0.11.0-macosx.patch then in terminal again

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

when you get to this point and downloaded the qemu-0.11.0-olive.patch

wget http://downloads.sourceforge.net/gns-3/ ... h?download

then do

- go to the qemu-0.11.0 folder and rename the qemu-0.11.0-olive.patch?download to qemu-0.11.0-olive.patch then in terminal again

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

./configure --disable-aio --disable-kvm --disable-kqemu --disable-sdl --target-list=i386-softmmu

make

If you get an issues with compiling and get the following

CC vnc-tls.o
In file included from vnc.h:80,
from vnc-tls.c:27:
vnc-tls.h:31:27: warning: gnutls/gnutls.h: No such file or directory

vnc-tls.c: At top level:
vnc-tls.c:67: error: expected ‘)’ before ‘transport’
vnc-tls.c:84: error: expected ‘)’ before ‘transport’

then copy the gnutls folder located in opt/local/include/ into the qemu-011.0 folder

make
sudo make install

this should then install qemu when clicking on the test button



as you can see from the picture qemu and qemu-img is set

/usr/local/bin/

now that you have done this you must run qemuwrapper first before you start gns3

Assuming that you have gns3 in your applications folder go to terminal and run the following

python /Applications/GNS3.app/Contents/Resources/qemuwrapper.py

you will see terminal say

Qemu Emulator Wrapper (version 0.8.2)
Copyright (c) 2007-2011 Thomas Pani & Jeremy Grossmann

Qemu path (qemu) is valid
Qemu-img path (qemu-img) is valid
Qemu TCP control server started (port 10525).
Listening on all network interfaces


leave it running

Start gns3

when you place an ASA, Juniper etc image you will get the following warning



just click OK and ignore

I setup a ASA and router just to show connectivity



Hope this helps

10.7 Install

To get 10.7 working this is a little different. I followed the following post

https://sites.google.com/a/ovnetworks.com/index/blog/qemujunosonosx1073

I have to admit alot of this stuff I did not follow. I did the following

Then, download Qemu 0.14.1 from this page : http://download.savannah.gnu.org/releases/qemu/
and patch it with 0.14.1 patches on this link download/file.php?id=859

sudo tar xjf qemu-0.14.1.tar.gz
sudo rm xjf qemu-0.14.1-gns3_patches.tgz

sudo mv qemu-0.14.1_* qemu-0.14.1
cd qemu-0.14.1

sudo patch -p1 -i qemu-0.14.1_hw_e1000_c.patch
sudo patch -p1 -i qemu-0.14.1_block_raw-win32_c.patch
sudo patch -p1 -i qemu-0.14.1_Makefile_objs.patch
sudo patch -p1 -i qemu-0.14.1_net_c.patch
sudo patch -p1 -i qemu-0.14.1_net_h.patch
sudo patch -p1 -i qemu-0.14.1_net_udp_c.patch
sudo patch -p1 -i qemu-0.14.1_net_udp_h.patch

You have also to copy the "gnutls" folder in your Qemu folder :

/opt/local/include/gnutls

Now, configure Qemu with the following options :

sudo ./configure --prefix=/usr/local --disable-sdl --enable-cocoa --disable-docs --target-list="i386-softmmu x86_64-softmmu" --cc=/usr/bin/gcc-4.2 --host-cc=/usr/bin/gcc-4.2

Compile and Install :

sudo make
sudo make install

After that, you can check that Qemu works and loads a Junos image :

sudo qemu -L . -m 512 -hda junos.img -serial telnet:127.0.0.1:1001,server,nowait,nodelay -localtime


he also mentioned about the JUNOS image which I was unable to get to work. If anyone was able to be a working bios.bin image if you could PM or paste a link to download that would be great :)

Jeremy NOTE

I think it might be a good idea to update the http://blog.gns3.net/2009/10/olive-juniper/2/ and add these extra steps for people that are having issues

Hi franco,

I did everything you described in your post, the ASA is working fine but that's only without any connection. If I connect a port to a router it won't startup. Do you know what's going on?

Krgds,

Hi Mylex

I have updated the instructions again and seem to have it working fine with pings. Sorry for the issues but hope this now helps

Hi Franco,

Thanks for your guide.

I'm hoping you might be able to help me , I'm trying to build qemu on lion but I had to install xcode 4.3 from the appstore and it doesn't seem to come with gcc. Every time I run
./configure --disable-aio --disable-kvm --disable-kqemu --disable-sdl --target-list=i386-softmmu
I get "ERROR: "gcc" either does not exist or does not work" and so can't progress with the rest of the guide.

Is there any way round this? can I use your built qemu for lion?

Any help would be much appreciated.

Hey Franco thanks for the guide. I was able to compile the 2 files and do a test successfully. Problem is every time i try to start a qemu host it crashes with the following report. Just wondering if your or anyone else has seen this problem. Thanks

Hi,

tried to apply your procedure to install Qemu on MAC OSX 10.6.8.

python /Applications/GNS3.app/Contents/Resources/qemuwrapper.py
Qemu Emulator Wrapper (version 0.8.2)
Copyright (c) 2007-2011 Thomas Pani & Jeremy Grossmann

Unable to start Qemu: [Errno 2] No such file or directory
Path to Qemu seems to be invalid, please check. Current path is qemu

I attached the termial output.

Can someone help me with this.

Thanks

Hello, I am having exactly the same problem under 10.7.3 . I tried with qemu 0.11 and now 0.14. Both gave me the error above. I replaced the Freebsd iso, but that did not make any difference either.
Everything else went just fine. (configure/make/install). Also testing the qemuwrapper in GSN3 gave me the ok.
I know this post is from a while back so I was wondering if there has been a solution found in the mean while because I am unable to build an img because of this problem.
Thanks.

I have built and installed the latest QEMU 1.1.1 on OSX from the sources. This version has UDP tunnelling built in so no patching required. AFACS the command syntax for -net,nic is different to the earlier patched version which is called from qemuwrapper.py - I'm referencing Brezular's article at http://brezular.wordpress.com/2011/04/02/gns3-qemu-troubleshooting/ so this may have changed?

QEMU 1.1.1 compiles cleanly on OSX 10.6.8 - http://rubenerd.com/qemu-1-macosx/ was a useful pointer. I just built everything.


QEMU can be found at /usr/local/bin/qemu-system-i386 and /usr/local/bin/qemu-system-x86_64.

I loaded up a Microcore appliance in QEMU. I've configured a startup script so it's easier to read the command line switches:

This is saved as microcore.sh and started by $sh microcore.sh

The corresponding connection in the .net file is

connect this to a router ethernet interface or switch port.

I must confess at this point I'm not using GNS3, I'm using Dynagen/Dynamips and creating my .net files by hand.
