There are several log files that MDT creates during various stages of the deployment/capture problem. The TechNet article ‘Understanding Failures and Log Files’ will help you find them so that you can see what errors may be present. Another tip for MDT’s log files is to set the rule SLShare="path to deployment share" in your deployment share rules (customsettings.ini file). This will copy all of the log files to that location, making it easy to collect and view the log files for all of your deployments.
I also agree with MDT Guy about the network drivers. This VMWare knowledgebase article will help you extract the drivers from the VMWare Tools ISO. Then you will need to add them to the driver store and include them when you regenerate the boot images.
Lastly, the Deliver and Deploy Windows 8 page has the latest download link to the new version of MDT (2013) and many articles and videos to help you with deploying Windows.
