1. A method for handling storage in response to migration of a virtual machine in a virtualization environment, comprising:
receiving an I/O request for an unshared virtual disk owned by a first service virtual machine, wherein a second service virtual machine receives the I/O request; determining that the second service virtual machine which implements a storage controller is not registered as owner of the unshared virtual disk, wherein only a service virtual machine registered as owner of the unshared virtual disk is permitted to access the unshared virtual disk to implement the I/O request, and wherein the act of determining occurs in response to the second service virtual machine receiving the I/O request for the unshared virtual disk owned by the first service virtual machine; transferring ownership of the unshared virtual disk from the first service virtual machine to the second service virtual machine; and the second service virtual machine implementing the I/O request after obtaining ownership of the unshared virtual disk. |
