As you are having issues with the install, I might suggest creating a more modest sized disk image, at least during testing --- It would be a rare test case that would need more than 8 G for a CentOS image while you are still solving setup issues We have supported guest images up to 400G for one user who kept re-sizing an image up and up from an initial 4G to over 400 G ... eventually the 2 1/2 hour lag in moving content from one big image to another bigger image caused him to ask why it was taking so long. When our interface 'resizes' an image, it takes a safety snapshot first to an NFS backup store, tests is, and only then deletes the old image and creates the old one ... so it takes a while for images over say 100 G. The delays you note do not surprise me -- it takes time to reliably shuttle bits around a disk, and no cacheing effects are possible with off the shelf setups (i.e., lacking huge memory based drives) to support such large image sizes -- Russ herrold
