KVM is based on the underlying CPU hardware-assisted virtualization technology, so it needs CPU support for virtualization features to be realized.

According to the direction of business and data traffic, data center traffic can be divided into north- south traffic and east-west traffic.

A company deploys an online trading system on the FusionCompute virtualization platform. In order to ensure the reliability and performance of the online trading system, it is reco...

In FusionCompute, if the HA policy is set to restore the virtual machine from the original host, when the host where the virtual machine is located fails, the system must wait for...

Metal virtualization directly uses Hypervvisor to call resources for virtual machines, does not depend on the underlying operating system, and reduces process scheduling, so perfor...

A company deploys an online transaction system on the FusionlCompute virtualization platform. In order to ensure the reliability and performance of the online transaction system, i...

Hot adding of virtual machine resources refers to adding computing, storage and network resources to a virtual machine when the virtual machine is powered on.

Two hosts A and B on the same network segment are interconnected through two Layer 2 switches, and hosts A and B belong to different VLANs. At this point, the two hosts can communi...

A user has made multiple snapshots for a virtual machine on FusionCompute, but the restoration of the virtual machine using the third snapshot fails. The reason may be that the sec...

Enterprises can use virtualization technology to run multiple virtual machines on one physical server, and at the same time, they can migrate virtual machines between different ser...

The CPU QoS of the virtual machine is used to ensure the computing resource allocation of the virtual machine, isolate the computing power interaction between the virtual machines...

In the KVM architecture, QEMU simulates and executes I/O type operation requests for the virtual machine through software simulation.

KVM itself does not perform any hardware simulation functions, but only provides an interface responsible for the creation of vCPU and the allocation of virtual memory address spac...

SATA hard disk adopts parallel connection mode, supports error automatic correction and hot swap function.

Through VIMS, FusionCompute manages virtual machine images and configuration files in the form of files.

I/O virtualization can be divided into full virtualization, paravirtualization, and hardware-assisted virtualization. Among them, hardware-assisted virtualization completely uses s...

A virtual machine can create multiple snapshots to form a snapshot chain, and any operation on one of the snapshots will not affect other snapshots.

Horizontal expansion means that when the business volume continues to grow, it is not necessary to upgrade the server specifications, but only need to increase the number of server...

The KWM virtual machine can be created through a graphical interface or a command line.

KWM is an open source full virtualization solution.

Open source virtualization technologies are all type I virtualization, and closed source virtualization technologies are all type II virtualization.

NAS has its own independent file system. After the application server accesses the NAS through the network sharing protocol, it can read and write files in the file system.

What SAN provides to the host is a "bare disk" without a file system. What file system to build on it depends entirely on the host's operating system.

In Huawei FusionCompute, the system disk of the virtual machine cannot be unbound.

SSD disk is a mechanical hard disk, which has the advantages of fast read and write speed, low power consumption, and light weight, but it has a limited service life.

In cloud computing, the network can be divided into virtual network and physical network.

In Huawei FusionCompute, DVS not only supports configuring static routing, but also supports multiple dynamic routing.
