backup kvm virtual machine

Concept:Kernel-based virtual Machine is an open source system virtualization module that has been integrated into various major distributions of Linux since Linux 2.6.20. 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 in academia today.KVM Virtualization requires hardware support

backgroundBecause the server in the production environment does not install the desktop environment, a graphical installation of simple operations is not suitable for batch deployment installations. Therefore, I prefer to install the KVM virtual machine under the command. In combination with some information and personal use, I have outlined some basic and common

KVM Virtual machine migration is divided into 4 types (1) Thermal migration is based on shared storage (2) Thermal migration based on local storage (3) Cold migration is based on shared storage (4) Cold migration based on local storage This is a hot migration based on local storage. Dynamic Block Migration version requirements QEMU version requires greater

First, KVM IntroductionKVM is open source software, the full name of kernel-based virtual machine (kernel-based VM), is an open source system virtualization module, hardware-based complete virtualization, but requires hardware support (such as Intel VT Technology or AMD V technology). Since Linux 2.6.20 is integrated in each major release of Linux. It is managed

I remember someone previously asked "can I run a virtual machine on a virtual machine". Of course, the answer is yes. hypervisors such as Xen HVM, KVM, VMware, and Qemu can all NEST virtual machines like this, however, low perform

Currently, the virtual machines virtualized by the company in KVM are dual ip addresses, that is, a floating ip address and a fixed ip address used by a virtual machine. When installing the jboss application server, the host. xml configuration file must specify the management ip address for managing the application ser
