Abstract
A computer-implemented method for preserving an independent virtual disk. The method, includes attaching an independent virtual disk to a first virtual machine, and preserving said independent virtual disk when the independent virtual disk is detached from the first virtual machine.
Claims13
A computer-implemented method for preserving an independent virtual disk, said computer-implemented method comprising:
- creating a shell virtual machine;
- creating an independent virtual disk wherein said independent virtual disk is held by said shell virtual machine which does not access and process data related to said independent virtual disk;
- assigning an unique identifier to said independent virtual disk such that said independent virtual disk is able to survive after said independent virtual disk is detached from said shell virtual machine;
- detaching said independent virtual disk from said shell virtual machine;
- attaching said independent virtual disk to a first virtual machine of a plurality of virtual machines;
- preserving said independent virtual disk in response to said independent virtual disk being detached from said first virtual machine;
- and
- attaching said independent virtual disk to a second virtual machine.
