Error when building a VirtualBox appliance

[salman.kagzi]

I am trying to create a CentOS 6 appliance with my software installed.

I have got the build file done with and am able to build appiance for

1. KVM
2. VirtualPC
3. VMWare
4. ec2

but for some reason the VirtualBox is not working. I am getting following error when trying to build a VirtualBox appliance.

I am using following command to build virtual box appliance:

boxgrinder-build centos6.appl -p virtualbox -d local --delivery-config path:/home/boxgrinder,overwrite:true,package:true

Can somebody let me know what I am doing wrong with this?

[salman.kagzi]

Problem mentioned above was seen when using box grinder on fedora 17 on a Virtual Box. This does not seem to be happedning with Meta Appliance EMI.

Is there are dependency that needs to be installed when using Fedora 17 for Box grinder?

I'm currently combining forces with another related project ( to merge BoxGrinder's functionality, with the view of providing feature parity and a migration path over. Unfortunately this has left some bugs unresolved.

If you edit the file at the line you quote, and change the code to

     if is_os_old? or !@appliance_config.post['virtualbox']

Does it resolve the problem?

Quick note that I believe I am getting the exact same bug

I am using the meta appliance (ami-40058870) which I have upgraded to 10.4 (boots to 10.0)

I am successfully building an appliance in the ec2 format w/ the ebs delivery module

when I try the same appliance configuration in the Virtualbox format with local delivery I get this error:
