(1) The concept of virtualizationVirtualization is the simultaneous running of multiple virtual machines on physical devices that share the CPU, memory, and network of physical devices, but these VMs are isolated from each other.The physical machine is called host (host), and the virtual machine is called guest.(2) Classification of virtualizationVirtual machine scheduling management relies on hypervisor software, according to the location of hypervisor, can be divided into 2 major categories:1,

Background: In the automated testing industry, individuals feel that the main language is Python, java. This discussion is based on the Python automation framework design and case development, using Python know its benefits, but according to the actual project needs have a lot of oncoming difficulties-host migration, environmental clutter, external impact. These problems are very bad, causing great trouble for the developers, which leads to the inability to maximize the role of automated testi

Virtualization Technology (VT), which is a virtualization technology, is supported by most CPUs in Intel and AMD, named Vt-x, Amd-v, respectively. VT has greatly improved the performance of Android simulators such as VMware, Seahorse play, and reliable assistants. Here is a small weave to see how to open VT in the BIOS

that the traffic from the VM can be directly sent to the specified queue through the software switch, and the software switch does not need to perform sorting and routing operations. However, the vmm and vswitch still need to copy the network traffic between the vmdq and VM. SR-IOV For the SR-IOV, it is more thorough, by creating different virtual functions (VF), presented to the virtual machine is an independent NIC, therefore, the virtual machine directly with the NIC communication, yo

PNS Virtual desktops, Voi intelligent virtual desktops, and IDV virtual desktops? Today, a friend in the forum asked this question, small white and I have expressed a little surprised, because very few heard, so interested to go online search a lap, these years mainstream and non-mainstream virtual desktop technology to do a collection. VDI (virtual Desktop infrastructure-Remote Desktop based on virtual machine resources alone- Individuals will mai

One Virtual Switch member chassis will be a member of the primary virtual switch, and another member will be in the hot wait state of the control Panel. The data panels for both enclosures are available, so the total traffic forwarding capability is 1440Gbps. When a virtual switch member fails, there is no need for protocol r
