  • INFOCOM - A Holistic Model for Performance Prediction and Optimization on NUMA-based virtualized Systems
    IEEE INFOCOM 2019 - IEEE Conference on Computer Communications, 2019
    Co-Authors: Qian Jianmin, Haibing Guan
    Abstract:

    The non-uniform memory access (NUMA) architecture has become the dominant server architecture due to its scalable bandwidth performance. However, the NUMA architecture also introduces the complicated performance influences to the applications, because of the differentiated remote devices access latency and shared resource access contention. Secondly, quick developments of high speed networking devices make I/O resource be another important performance affecting element for I/O-intensive cloud applications on NUMA server. Thirdly, it is more critical in virtualized environment since all resources are managed uniformly and transparently to the VM, and the application behaviors in the VM are shielded from the virtual machine manager (VMM). In this paper, we first give an analytic evaluation for performance influence from the various resource affinity. Motivated by the observations, we then build an accurate performance prediction model, named Resource Affinity performance Influence Estimation (RAIE). RAIE provides a novel performance prediction model with the holistic resource affinity parameters that are measured with the platform independent quantification approaches that need be executed in one-off manner. Moreover, RAIE model takes into account the actual influence of resource affinity according to the VM behaviours that can be monitored online without VM modification. Comprehensive evaluations prove that the RAIE model for a VM’s performance prediction can increase the average prediction accuracy by 3.27x on a 4node NUMA server with high speed Network Interface Cards (NIC). The RAIE guided scheduling case validates that it can achieve 2.1x performance improvement for actual VMM resource management servicing a VM running the dynamic applications.

  • Workload-Aware Credit Scheduler for Improving Network I/O Performance in virtualization Environment
    IEEE Transactions on Cloud Computing, 2014
    Co-Authors: Haibing Guan
    Abstract:

    Single-root I/O virtualization (SR-IOV) has become the de facto standard of network virtualization in cloud infrastructure. Owing to the high interrupt frequency and heavy cost per interrupt in high-speed network virtualization, the performance of network virtualization is closely correlated to the computing resource allocation policy in virtual machine manager (VMM). Therefore, more sophisticated methods are needed to process irregularity and the high frequency of network interrupts in high-speed network virtualization environment. However, the I/O-intensive and CPU-intensive applications in virtual machines are treated in the same manner since application attributes are transparent to the scheduler in hypervisor, and this unawareness of workload makes virtual systems unable to take full advantage of high performance networks. In this paper, we discuss the SR-IOV networking solution and show by experiment that the current credit scheduler in Xen does not utilize high performance networks efficiently. Hence we propose a novel workload-aware scheduling model with two optimizations to eliminate the bottleneck caused by scheduler. In this model, guest domains are divided into I/O-intensive domains and CPU-intensive domains according to their monitored behaviour. I/O-intensive domains can obtain extra credits that CPU-intensive domains are willing to share. In addition, the total number of credits available is adjusted to accelerate the I/O responsiveness. Our experimental evaluations show that the new scheduling models improve bandwidth and reduce response time, by keeping the fairness between I/O-intensive and CPU-intensive domains. This enables virtualization infrastructure to provide cloud computing services more efficiently and predictably.

  • SR-IOV Based Network Interrupt-Free virtualization with Event Based Polling
    IEEE Journal on Selected Areas in Communications, 2013
    Co-Authors: Haibing Guan, Yaozu Dong, Kun Tian
    Abstract:

    Along with the developments of networking and virtualization technologies, high speed network connections have become one of the key components in cloud computing and data-centers. Single-Root I/O virtualization (SR-IOV) enhances the network throughput to the extent of becoming close to the line rate and achieving high scalability in the 10Gbps and higher network environments. However, the overhead of SR-IOV interrupt virtualization remains significant due to some additional trap-and-emulation overhead on the virtual interrupt controller. The higher the virtualization network connection is, the higher the interrupt frequency becomes through high bandwidth network. To mitigate this problem, we propose a smart Event-Based Polling model (sEBP), which leverages existing system events to trigger a regular packet polling such that network interrupts are eliminated from the critical I/O paths in the virtual environment. Due to the many varieties of system events, sEBP can deal with the network workload in a configurable and flexible manner. Based on a hierarchical virtualized environment, it can also be implemented either at the guest OS kernel level or at the virtual machine manager (VMM) level. Since polling is much lighter than interrupt processing, sEBP significantly reduces the network processing overhead. The experimental results prove the efficiency of sEBP, which can achieve up to a 59% performance improvement and a 23% improved scalability ratio.

  • Hyper-V for VMware Administrators: Migration, Coexistence, and Management
    2015
    Co-Authors: Brien Posey
    Abstract:

    Learn to deploy and support Hyper-V, building on what you know about VMware's vSphere. Whether you're looking to run both hypervisors in parallel or migrate completely, Hyper-V for VMware Administrators has everything you need to get started. The book begins with an overview of Hyper-V basics, including common management tasks such as creating a virtual machine and building a virtual network. You'll learn how to deploy a failover cluster to protect against the risk of Hyper-V becoming a single point of failure, and how to make virtual machines fault tolerant. System Center virtual machine manager (SCVMM) is the preferred tool for managing large Hyper-V deployments, so you'll get to know this next and how it differs from VMware's vCenter solution, as well as how to manage a mixed environment including both vSphere and Hyper-V deployments. Like any server migration, a virtual server migration requires careful planning to ensure success. You'll find information here on the specifics of migrating from vSphere to Hyper-V, planning for down time, IP address differences, performance considerations, and more. For migrations to Hyper-V, SCVMM is once again the preferred tool, but you'll also be introduced to some of the excellent free tools available. One easily overlooked aspect of the migration process is the way in which it impacts your backup and recovery strategy. Knowing the best practices here can help you protect your Hyper-V environment. The book also covers how to monitor and maintain your Hyper-V environment once it's up and running, using features like Cluster-Aware Updating, automated live migrations, and availability sets. The concluding chapter shows you how to take advantage of the efficiencies provided by virtual machine libraries and templates. Approach Hyper-V with confidence, and the knowledge that you've planned for success, with Hyper-V for VMware Administrators. What youll learn Find out how Hyper-V compares to VMware's vSphere, and how System Center virtual machine manager compares to vCenter. Prevent Hyper-V from becoming a single point of failure with failover clustering. Work with System Center virtual machine manager to manage both Hyper-V and vSphere environments through a single interface. Plan and execute a virtual server migration, including planning for downtime, IP address changes and performance considerations. Adapt your backup and recovery strategy for best results in your new Hyper-V environment. Monitor and maintain your Hyper-V clusters, using Cluster-Aware Updating, automated live migrations, and availability sets. Use virtual machine libraries and templates for increased efficiency. Who this book is for Readers should have a working knowledge of vSphere 5.5. No prior experience with Hyper-V is expected.

  • An Introduction to System Center virtual machine manager
    Hyper-V for VMware Administrators, 2015
    Co-Authors: Brien Posey
    Abstract:

    So far in this book, we have been using the Hyper-V manager and the Failover Cluster manager as our primary management tools for Hyper-V. As I mentioned in the first chapter, however, these tools tend to be inadequate for managing larger Hyper-V Deployments. In this chapter, I want to introduce you to another management tool called System Center virtual machine manager. We will be using System Center virtual machine manager quite a bit in the coming chapters.

  • Using virtual machine manager as a Cross-Platform Management Tool
    Hyper-V for VMware Administrators, 2015
    Co-Authors: Brien Posey
    Abstract:

    In the last chapter, we set up System Center virtual machine manager. Even so, our VMM server really doesn’t do much yet. As such, this chapter is all about putting virtual machine manager (VMM) to work. The main goal of this chapter is to show you how to connect virtual machine manager to both Hyper-V and vSphere and to demonstrate how to use it as a cross-platform management tool. We will start out by bringing our virtualization hosts under management by deploying the required agents. As we go along, I will show you some techniques for using VMM to manage your virtualization infrastructure.

  • CCGrid - T-VMI: Trusted virtual machine Introspection in Cloud Environments
    2017 17th IEEE ACM International Symposium on Cluster Cloud and Grid Computing (CCGRID), 2017
    Co-Authors: Lina Jia, Min Zhu
    Abstract:

    Nowadays, the vulnerability of cloud environment exposed in security places virtual machine Introspection(VMI) at risk: once attackers subvert any layers of cloud environment, such as host, virtual machine manager(VMM) or qemu, VMI will be exposed undoubtedly to those attackers too. Nearly all existing VMI techniques implicitly assume that both VMM by which VMI accesses specific VM data and host which VMI is running on, are nonmalicious and immutable. Unfortunately, this assumption can be potentially violated with the growing shortage of security in cloud environment. Once VMM or host is exploited, attackers can tamper the code or hijack the data of VMI, then, falsify VM information and certifications to Cloud system's administrators who try to make sure the security of specific VM in certain compute node. This paper proposes a new trusted VMI monitor frame: T-VMI, which can avoid the malicious subversion of the routine of VMI. T-VMI guarantees the integrity of VMI code using isolation and the correctness of VMI data using high privilege level instruction and appropriate trap mechanism. This model is evaluated on a simulation environment by using ARM Foundation Model 8.0 and has been presented on a real development ARMv8 JUNO-r0 board. We finished the comprehensive experiments including effectiveness and performance, and the result and analysis show T-VMI has achieved the aim of expected effectiveness with acceptable performance cost.
