Abstract
The instant disclosure describes embodiments of a system and method for migrating virtual machine (VM)-specific content cached in a solid state drive (SSD) attached to an original host. During operation, the original host receives event indicating an upcoming migration of a VM to a destination host. In response, the original host transmits a set of metadata associated with the SSD cache to the destination host. The metadata indicates a number of data blocks stored in the SSD cache, thereby allowing the destination host to pre-fetch data blocks specified in the metadata from a storage shared by the original host and the destination host. Subsequently, the original host receives a power-off event for the VM, and transmits a dirty block list to the destination. The dirty block list specifies one or more data blocks that have changed since the transmission of the metadata.
