Abstract:
Methods for obtaining a snapshot of a shared virtual machine (VM) image are described herein. In response to a request for obtaining a snapshot of a first VM image stored in a storage disk accessed and shared by a plurality of VMs, a virtualization manager selects a VM from the plurality of VMs hosted within one or more hosts. First needs to notify others to prepare for the snapshot by pausing, etc. A process associated with the selected VM is configured to capture a snapshot from the first VM image, generating a second VM image to be stored in storage disk. Thereafter, the virtualization manager notifies the plurality of VMs to utilize the second image after the second VM image has been generated.
