Fast and Live Replacement of Hypervisors and Operating Systems

New technology replaces a hypervisor without disturbing running Virtual Machines Background: Hypervisors and operating systems are becoming increasingly complex and must be often updated for applying security patches, bug fixes, and feature upgrades. However, updates to an operational hypervisor or OS can be highly disruptive. Before being updated,...

Recovering Virtual Machine from Failure of Post-Copy Live Migration

New approach to recover a Virtual Machine during post-copy live migration Background: Post-copy is one of the two key techniques (besides pre-copy) for live migration of virtual machines in data centers. Post-copy provides deterministic total migration time and low downtime for write-intensive VMs. However, if post-copy migration fails for any...

Security and Privacy Aware Virtual Machine Checkpointing

A security and privacy aware checkpointing mechanism that enables users to selectively exclude processes and terminal applications that contain sensitive data from being checkpointed. Background: Virtual Machine (VM) checkpointing enables a user to capture a snapshot of a running VM on persistent storage. VM checkpoints can be used to roll back...

Span Virtualization: Multi-hypervisor Virtual Machines

A new virtualization architecture that leverages nesting to allow multiple hypervisors to concurrently control a guest’s memory, virtual CPU, and I/O resources. Background: Public cloud software marketplaces already offer users a wealth of choice in operating systems, database management systems, financial software, and virtual networking,...

Multi-Hypervisor Nested Virtual Machines

A Multi-hypervisor Virtual Machine (VM) in which a single VM can simultaneously run on multiple hypervisors. Background: Standard nested virtualization allows a hypervisor to run other hypervisors as guests, i.e. a level-0 (L0) hypervisor can run multiple level-1 (L1) hypervisors, each of which can run multiple level-2 (L2) virtual machines (VMs),...

Gang Migration of Virtual Machines using Cluster-wide Deduplication

Simultaneous live migration of multiple virtual machines (VMs) from one set of physical machines to another Background: Gang migration refers to the simultaneous live migration of multiple virtual machines (VMs) from one set of physical machines to another. Gang migration generates a large volume of network traffic and can overload the core...
