kvm vs vmware

When installing a virtualized environment, first look at the hardware configuration and environment of the server, as follows:(a) Check the hardware related situation:1, view CPU model, number of physical CPUs,[Email protected] ~]# Cat/proc/cpuinfo |grep name |Cut-d:-f2 |Uniq-c 2 Intel (R) Core (TM) i3-4150 CPU @ 3.50ghz[[email protected] ~]# Cat/proc/cpuinfo |grep Physical |Sort-n | Uniq-c 2 Address sizes:42 bits physical, bits virtual physical id:0 # #说明有一颗cpu, the number is from 0 starting fr

machine is running, you can view the CPU usage: After the installation is completed as shown; Turn off the virtual machine and turn the virtual machine off by entering the shutdown command on the virtual machine; Based on the Virt-manager to create the management virtual machine is complete, very simple. We use the Cirros lightweight Linux system for the following experiments. Two. The network model of the KVM virtualization platform 1. N

Introduction to KVM:KVM, an open source system virtualization module, is integrated into the major distributions of Linux since Linux 2.6.20. It uses the Linux own scheduler import row management, therefore relative to Xen, its core source code is very few. KVM has become one of the mainstream VMM in academia today. KVM Virtualization requires hardware support (such as Intel VT Technology Ring AMD v technol

same as the Virtual Machine file in the/etc/libvirt/qemu directory. The PID file contains the Virtual Machine Process number. The virtual machine log files are stored in the/var/log/libvirt/qemu directory. Each virtual machine has one file named: Virtual Machine name (or UUID) + ". log" 7) qemu does not use the vncserver in Linux to provide the VNC service. Therefore, if the service is not started, it can also be connected to the virtual machine through the VNC client. The above configuration

KVM Virtual machine Dynamic migration requires no copying of virtual disk files, but requires the same directory structure virtual machine disk files between the virtual hosts that need to be migrated, compared to the need to copy virtual machine virtual disk files in the static migration of a KVM virtual machine. This part of this article is implemented by NFS, and of course it can be implemented by the

Multi-thread compression and Migration Technology in QEMU-KVM, qemu-kvm MultithreadingMulti-thread compression and Migration Technology in QEMU-KVM Guide Currently, the Migration technology is to directly write raw memory data to QEMUFILE to transfer virtual machines. In this case, a large amount of data is sent, this results in a higher migration t

in a more collaborative manner. This is because every customer's operating system understands that he is running in virtualization mode. Therefore, every system works with the system management program to achieve virtualization of underlying hardware. Examples of full virtualization include commercial virtualization solution VMware and the IBM System z9 Virtual Machine (z/VM) operating System used on commercial IBM zSeries computers. Quasi-virtualiza
