| | 65 | * Installing the guest on '''fixed size''' disk images. Until version 1.5.4, !VirtualBox creates a sparse file if the user selects 'fixed size' when creating a virtual disk image. That means that the file is created and its length on the real hard disk is defined but the file content is still not allocated. When trying to install a guest OS on this image, the first write accesses to a sector in the middle of the image will be delayed for a long time on Windows hosts. This might confuse the guest and make installing a guest impossible (for example, '''creating a partition fails'''). Starting with !VirtualBox 1.5.6 we will write the whole file once during creation. Users of current versions should select a ''dynamically expanding'' image which does not have this limitation. |
