1 Masters Project Proposal Virtual Machine Storage Performance Using SR-IOV by Michael J. Kopps Committee Members and Signatures Approved By Date Advisor: Dr. Jia Rao Committee Member: Dr. Xiabo Zhou Committee Member: Dr. C. Edward Chow
2 Abstract This paper outlines a proposal to analyze the performance differences of the storage model on KVM virtual machines when using SR-IOV versus using the traditional Dom0 assisted storage techniques. SR-IOV presents physical hardware devices to the virtual machines and removes the overhead of the hypervisor when making disk IO operations. The goal of this research is to show the degree of performance benefits when removing the hypervisor from the disk IO stack. Introduction Kernel based Virtual Machine (KVM) is a virtualization hypervisor which uses QEMU and is rapidly growing in industry adoption for virtualizing servers. The architectures of the underlying hardware this hypervisor runs on vary widely, but there is always a need for the basics: CPU, memory, network, and persistent storage. CPU and memory virtualization is able to take advantage of CPU hardware such as Intel s VT-x and VT-d to simplify virtualization by the hypervisor operating system. The persistent storage system, which in any computer virtualized or native has always been the largest, least expensive per gigabyte, and slowest form of data storage technology, has struggled to find an easy hardware accelerated virtualization architecture. On virtualization platforms such as KVM, the storage represented is in reality either a file on the hypervisor s file system or a partition on a physical disk set up by the hypervisor. These methods have benefits such as simplicity and ease of management, but they also require the hypervisor to be involved in all disk IO operations, adding an extra layer and therefore extra latency to the already slow persistent storage. When the storage is really a partition on a disk partitioned by the hypervisor, the overhead is small as the hypervisor merely needs to forward the requests on to the disk. On the other hand, when the storage is really a file, all of the requests need to be translated and then passed through the file system of the hypervisor, increasing latency. The latter approach has the benefit of being able to migrate the storage (and the associated virtual machine) easily since the file just needs to be copied. The former approach must resize partitions on the destination disk in order to provide
3 room for the migration. However, the performance of the IO will suffer as a result of the additional layers each request must go through. Single-Root IO Virtualization (SR-IOV) was developed by the PCI-SIG to allow multiple virtual machines to access the same physical PCI-Express devices as if each virtual machine had their own dedicated device [1]. This technology is growing in use in network interface cards and the performance benefits in that space has been widely seen. This technology has not seen wide adoption in the hard disk host bus adapter (HBA) space, and there is very little known as for the performance benefits of allowing virtual machines to communicate directly to the HBA. This work will set up a sample system with a SR-IOV capable HBA and measure its performance compared with the same system without SR-IOV enabled along with a system running Linux natively without virtualization. Even with SR-IOV, the hypervisor is not completely out of the I/O path due to the need to handle and route interrupts. The hardware will still issue interrupts to the hypervisor operating system, which must then pass those interrupts on to its guests. Secondly, since it requires direct memory access from the hardware, protection should be provided to prevent the hardware from corrupting or accessing memory belonging to another virtual machine. This partitioning and security may be accomplished using an IOMMU, which is available in newer CPUs from both Intel and AMD. Previous Work Dong, et. al., has performed research in this area using network controllers. Their research has shown a significant performance boost when using hardware virtualization technologies [2]. In another paper, he has shown how to perform migration when using a pass-through network controller [3]. Further research was performed by Jiuxing Liu at IBM using 10Gbps network adapters. This work was very thorough and investigated many of the network driver optimizations available for the device used in the test [4]. Edwards, et. al., performed research into storage nodes for cloud computing using a custom storage cluster system leveraging SR-IOV and the Xen hypervisor [5]. They showed the SR- IOV solution provided at least as good performance compared against bare-metal machines
4 accessing the same storage. Their work is aimed at a much larger solution using a centralized RAID engine and hundreds of disks on the SAS topology. There is very little work in the area of SR-IOV and disk controllers. This work will be groundbreaking in this area and will provide desperately needed information to help research as well as end users determine how to create the most efficient and highest performance virtualization platforms possible. Zhang, et. al., has performed a survey of performance research related to I/O in virtualized environments, and supports the idea passing as much work to the hardware will provide the most benefit to improving I/O performance [6]. Their performance testing on KVM shows a high CPU utilization with small block disk I/O operations, indicating the hypervisor is performing a great deal of work on each I/O. Their tests show as the I/O size gets larger, the amount of overhead gets smaller, and the CPU utilization is shown to taper off. Problem Definition The problem considered in this proposal is the unknown performance implications of SR- IOV in the storage controller domain. What effect does the hypervisor play in the storage access times experienced by the virtual machines? Can the virtual machines achieve native or near native performance when using SR-IOV enabled hardware? As a possible addition, can a virtual machine achieve near native performance when using SR-IOV on both its direct attached storage as well as its network interface? Can SR-IOV performance be modified with different schedulers? Proposed Plan The proposed solution for the problem this paper introduces can be split into five major phases: 1. Native Linux Performance Collection To compare the performance of SR-IOV based persistent storage, it will be interesting to know what the performance level of a bare-metal Linux system can be. The first test to be run
5 will be against the host operating system without any virtualization enabled. This will provide a baseline to compare all of the other results against. 2. Hypervisor Performance Collection Control data must then be collected to provide a baseline of performance in a virtualized system by which the SR-IOV controller may be compared. This will involve running IO benchmarks with the disk IO passing through KVM and QEMU into the FVD virtual disks [6]. This testing should be conducted with a variable number of guests running on the host system since most virtualization hypervisors will be running with 4 or 8 or even more guests running at once. Tests should be performed in the following configurations: 1 guest, 2 guests, and 4 guests performing benchmarks simultaneously. The IO benchmarks should represent normal server IO profiles using real file systems. These benchmarks should look at sequential and random block reads and writes, big block IO, and small block IO to identify bandwidth and IO per second limitations. Data should be collected to identify latency in completing the requests across all virtual machines. Bonnie++ is a file system based benchmark suite aimed at collecting performance data for hard drive and file system performance [8]. Data collection should also purge the file system cache to eliminate benefits only encountered in the test environment. 3. Configuring SR-IOV Storage The groundbreaking nature of this problem means there is no work either in literature or in publicly available documentation about how to set up and configure a SR-IOV enabled storage controller on a KVM system. LSI SAS controllers can be programmed to provide multiple virtual functions and provide SR-IOV services. The associated drivers will need to be compiled for a KVM system in order to take advantage of the feature, along with performing configuration such as the hard disk assignment to a particular virtual machine. An alternative to KVM is available in the Xen, which is available for various Linux distributions and is very widely used [9]. Xen is primarily a para-virtualized system and will be tested without using hardware virtualization to contrast against KVM [10]. Performance collection on Xen will be performed if time allows. 4. SR-IOV Performance Collection
6 Once the bare metal and hypervisor performance numbers have been collected, testing will focus on the performance when using a SR-IOV enabled hard drive controller. The same tests will be run in this configuration, again in fully virtualized configurations of guests and the same variety of number of guests on the system. 5. Data Analysis At this point of the research, all of the data which has been collected needs to be collated and analyzed for indications of performance variations between the various configurations. Conclusion The goal of this research is to determine if there is a significant performance benefit when removing the hypervisor from the IO path for disk access. It will also compare the disk access between KVM and a bare metal machine to see what performance differences exist between those configurations. This work will also identify performance optimizations that can drive future work in the virtual server storage system, with the goal of improving SR-IOV disk access in production systems.
