Περίληψη:
Live migration is a versatile option when it comes to attain
load-balancing in IaaS-cloud architectures. Liveness, reliability and
conformance to SLAs may all be achieved by moving a VM that creates
excessive work from its current physical machine (PM) to a less busy
node. Despite its promising features, live migration is an expensive
operation in terms of resources. The situation gets further exacerbated
when the movement involves PMs working off different file-systems which
is often the case in shared-nothing IaaS-cloud infrastructures. In this
paper, we suggest an approach that adapts the migration operation based
on the I/O activity of the originating-VM. We introduce LiveFS, a
FUSE-file system which traps all I/Os and helps determine how to best
ship virtual disk segments across PMs in a share-nothing IaaS-cloud.
Through prototyping and experimentation, we show that LiveFS can improve
the shipment of VMs for diverse types of workloads. In particular,
LiveFS succeeds in reducing the Total Migration Time by up to 64%
compared to the “pre-copy” live migration technique. Furthermore
during migration, we attain up-to 19% less I/O-delay if compared to the
“post-copy” livemigration approach.
