Abstract:
A method, an apparatus and an article of manufacture for controlling growth in virtual disk size. The method includes limiting a guest virtual machine file in a hypervisor from allocating a new disk block as allocated space, wherein a virtual disk on a virtual machine is mapped to the guest virtual machine file, and facilitating the virtual disk to reuse a previously allocated and freed disk block for the allocated space to control growth in virtual disk size.
