> Hi,

> In the above file, in the function 'create', I observed an argument 'files' wihch is taking 'None' by default. So, to test the primary functionality, I gave the 'files' argument statically in the function. For that, the first line of that function (Line no. 472) implementation, I defined 'files' as below:
> 
> fp = file('/root/inject.txt', 'r')
> files = {'/root/inject.txt':fp}
> 
> I followed two methods to create instance:

> 2. Through nova boot command from CLI

> After that, I restarted apache, and tried to create (launch) an instance from dashboard. It threw the following AJAX error, by clicking the Launch button:

> Error: There was an error submitting the form. Please try again.

> Method 2:
> If I did the same from nova boot command, the instance is creating and file injection is happening. Both methods are using the same above function 'create' in '/usr/lib/python2.7/dist-packages/novaclient/v1_1/servers.py'.

Hello Srikanth,

I am sorry but I am not familiar with the OpenStack dashboard or
/usr/lib/python2.7/dist-packages/novaclient/v1_1/servers.py

However I think you may find cloud-init valuable. https://help.ubuntu.com/community/CloudInit

Cloud-Init, once built into a client image, can be used to process data injected into a launch virtual
machine.

Cloud-Init is also available in EPEL and Fedora and soon to be in RHEL6.4

I just thought I would point it out as I think it could be valuable to you and the work
you are doing.
