grizzly: tomcat not required for vmware drivers

[Stephan Peijnik]

Even though the manual mentions that tomcat would be required for the vmware driver to work, this is not the case.

The original text in the manual ([0]) says, under prerequisites:

"Tomcat server: This is required to serve up a local version of the vSphere WSDL file (see below)."

and later on

"Next, download the SDK from http://www.vmware.com/support/developer/vc-sdk/ and copy it into /var/lib/tomcat6/webapps. You should ensure that the WSDL is available, in eg /var/lib/tomcat6/webapps/vmware/SDK/wsdl/vim25/vimService.wsdl. Below we will point nova.conf to fetch this WSDL file from Tomcat using a URL pointing to localhost."

However, tomcat is not required at all. Any other web server will do just fine. I have just verified this on a development setup, using nginx instead of tomcat.
Also, not the complete SDK is required, but rather the "vim25" folder and all of its contents. I have just verified this on my development setup as well.

This should probably be fixed, as tomcat uses a fair amount of resources, even though it is not required and keeping the whole SDK around uses some disk space, although not required either.

A few things:

1. a webserver isn't needed at all. I've documented this in the Wiki. We have an extra workaround in the driver that lets you skip setting up a webserver at all.

2. I've authored a script to automate the process of mirroring the WSDL and filling in the missing XML

3. I"m trying to figure out how to edit the document in the link. I can't seem to find it. I'll run through the documentation tutorials and try and submit an edit to this.
