I am in the middle of a disaster recovery situation trying to install ovirt 4.1 after a failure of some of our NFS systems. So I was redeploying 4.0 but there is a bug with the image uploader, that means I cant upload images. Our actually virtual machine hosts have very small HD's and the current 4.1 release installer thinks that the OVA extracted is 50GiB, I have exactly 50GB free! yay. So I did manage to hack the installer, to ignore my local disk space as the OVA is really only a few gigs in side. 

     But its been pretty painful. Any chance of some one fixing the estimate there, I have read through the code, there was an attempt to find out the real size but they gave up and just guessed.
