Hi Im running Win 7 and currently have no 'firwall' in place except for the standard Win 7 firewall.

I first downloaded the 'GNS.exe' and while learning how to setup a simple network which was ok, it also stated that if I wish to add a 'host pc' that I should download: GNS3-0.8.1-VirtualBox-Edition-Setup.

I then downloaded and installed 'GNS3-0.8.1-VirtualBox-Edition-Setup, but received error message: Failed to load vboxapi module, please check virtualbox installation.

I then uninstalled all traces of both 'GNS3' programs and then installed only - GNS3-0.8.1-VirtualBox-Edition-Setup - As this is so I can add a 'host pc'.

After installing all default settings as usual for GNS3 Virtualbox and click on Edit, Preferences, Virtualbox, I then click on 'TEST' but it states: Failed to load vboxapi module, please check virtualbox installation - Why has this problem not rectified itself ?

Download VirtualBox 4.1:

http://download.virtualbox.org/virtualb ... 13-Win.exe

Ive actually re-installed a clean install of Win 7 anyway.

So should I ignore my old 2 versions and use this version you have sent me?

Doesn't look like anyone is going to reply. Ive never ever used GNS3 before until yesturday!!!

Ive installed both GNS versions as stated in first thread on this question and now I can click on 'Test' for Virtualbox successfully but now I cannot now click on 'Test' on 'Dynamips' as it now states: Failed. Dynamips worked before and now it does not.!

I now have 2 versions of GNS3 on my desktop..

Last time I installed only 1 but still cannot get both Dynamips and Virtualbox working at same time!!

What a waste of time!!!!!!!!!!!!!!!!

Can anyone advise!?

I'll have a go at helping, but first of all can you let me know what you are trying to do?

If you want to use GNS3 to study Cisco routing, then you don't need Virtual Box. However, GNS3 is becoming an all-purpose-emulator-hypervisor-manager so perhaps Cisco is not your focus.

If Cisco IS your focus, then start either with the 0.8.1 virtualbox edition that you have already downloaded (don't be confused about the "virtualbox" in the title - it really is just GNS3 v0.8.1. It just happens to support virtualbox as well as Cisco and Qemu and pemu.

If you then want some PCs to connect to your Cisco routers, I'd suggest using vpcs rather than virtualbox - see the tutorial on how to set up vpcs - which by the way you also installed when you installed GNS3 0.8.1

Alternatively, you could download VMware Workstation and play with a pre-configured copy of GNS3. See the link in my signature for GNS3 Workbench.

Once you are familiar with GNS3 and how it works, then give the VirtualBox thing a go.

If on the other hand you want to get multiple virtual PCs talking to each other, then you need to let us know that that is your primary focus.

mikes11396:
Dynamips test fails due to incorrect paths. Please fix paths and this will work.

You can reset your configuration by doing:
Edit->Preferences->Configuration File->"Clear It" button and restart GNS3.

rednectar:
vpcs is *not* included with GNS3.

Oops. Sorry about the mis-information. you'll have to download VPCs separately from http://downloads.sourceforge.net/gns-3/vpcs-0.21a.zip if you want to use it. There is another tutorial here: http://www.gns3.net/gns3-hosts-topologies, as well as the GNS3 tutorial I referred to before.

VPCs is great for *simple* testing - if you want to do anything fancy like GLBP or IPv6 DHCP - then you are better off using real PCs - either VirtualBox PCs (easiest), VMWare PCs or real hardware.

Hi Ive installed: 'GNS3-0.8.1-VirtualBox-Edition-Setup' - I can select 'Dynamips' and 'Test' which is successfull everytime

I can configure routers no problem!!!

I wish to add a 'host pc' so that I have the capability to ping vica versa.!!

But when I click on 'Virtualbox' and 'Test' - This always fails!!!!!!!

This is the point at which I get to where I need your help!!!!!!?

U need to download VBox 4.1.x series (4.1.6 tested)

is there any news about this topic? the problem mikes11396 has mentioned is the same with mine.... and virtualbox 4.1.6 could not solve my "Failed to load vboxapi module, please check virtualbox installation" problem.
