I used to want to do this game, but I didn't find it difficult to do anything ready-made. But I still don't know the specific problem. I found this article yesterday and noted it down. It may be used in the future ..

F = 65 t = 154792 SID = 591087b7c7a8b9dcef3c39f297d78946 After studying KVM for a long time, I feel like I have used the fastest virtual machine. Compared with common virtual machines, VMWare has comprehensive functions and simple settings, but its speed is not very good. Although virtualbox is more efficient than VMWare, it has many disadvantages, it seems that the CPU is occupied during runn

KVM Virtual Machine IntroductionIntroduction to a KVM Virtual Machine (kernel-based Virtual Machine) is an open-source system virtualization module. It has been integrated into major Linux releases since Linux 2.6.20. It uses the Linux Scheduler for management, so compared with Xen, its core source code is few. KVM has become one of the mainstream VMM in the acad

I have encountered various bad things.

It is managed using Linux's own scheduler, so its core source code is few compared to Xen. KVM Virtualization requires hardware support (such as Intel VT Technology or AMD V technology) and is hardware-based full virtualization. The early days of Xen were software-based

Installation and use of KVM virtualization technology under LinuxThe advent of the cloud era, the widespread use of virtualization. Let's redefine the technology . And today's well-known virtualization products are VMware vsphere, HYPER-V,XEN,KVM. VMware is a marketplace for virtualization, and Hyper-V is virtualization under the Windows platform, and Xen is a semi-virtualized product.

Introduction to Nesting Virtualization Nested virtualization (nested virtualization, recursive virtualization) is the process of running a hypervisor in a virtualized client, which is then virtualized to run a client. Nested virtualization includes not only the same hypervisor nesting (for example, KVM on KVM, Xen in Xen, VMware on VMware, and so on), but also the different hypervisor nesting (such as VMwa

for processing graphics to maximize user experience and reduce system load. If the client is strong enough, Spice sends a graphics command to the client and processes the graphics in the client, significantly reducing the load on the server. On the other hand, if the client is not strong enough to handle graphics on the host computer, graphics processing does not require much spice from the CPU's point of view. Second, the installation and connection of spice software 1, Software Installation

Gentoo Installation Kvm+spice It's been heard long ago that spice is a lot more powerful relative to VNC, since it was installed with a 32-bit system that could not be tried, installed 64-bit systems, and had no time to toss. Last week has actually changed the graphics of the previous Windows virtual machine from VNC to spice, and yesterday it took care of the agent's startup and remote copy paste. First of all, installation, the process of installati
