virtio-net works very well for incoming network streams, but the external traffic occasionally degrades performance. Opening the queue Virtio increases the throughput, which correspondingly increases the burden on the CPU.It is necessary to do the necessary testing in the actual production environment before determining whether to use it. In RedHat, to use multi-queue virtio-net, add the following configuration to the virtual machine's XML file: then run the following command on the host:1 2.8

First, KVM IntroductionKVM (kernel-basedvirtual machine), a kernel-based VM, is a virtualized infrastructure used in the Linux kernel to transform the Linux kernel into a hypervisor. KVM was introduced into the Linux 2.6.20 core in February 2007 and ported to FreeBSD and Illumos in a way that can load core modules.KVM runs on an x86 platform with Intel VT or AMD-V capabilities. It is also ported to the S/39

KVM: (kernel-based virtual machine) kernel-based VMS KVM is hypervisor integrated into the Linux kernel, a full-virtualization solution for Linux with X86 architecture and hardware-enabled virtualization technology (Intel VT or AMD-V). It is a very small module of Linux, using Linux to do a lot of things, such as task scheduling, memory management and hardware device interaction and so on. In the form of pr

Introduced:KVM (kernel-based virtual machine, or kernel-level VM) is an open-source system virtualization module that is used for virtualization infrastructure in the Linux core, and KVM was introduced into the Linux 2.6.20 core in February 2007 and is Introduction of FreeBSD. It is managed using Linux's own scheduler, so its core source code is few compared to Xen. KVM has become one of the mainstream VMM

One, what is KVMKVM includes many parts: first, it is a Linux kernel module (now included in the mainline) used to convert the processor into a new user (Guset) mode. User mode has its own set of ring states, but the command of privileged RING0 is caught in the code of the manager (hypervisor). Since this is a new processor execution model, the code does not require any changes. In addition to processor state transitions, this kernel module also handles a small subset of low-level simulations,
