CentOS7 static IP online settings tutorial in virtual machine, centos7 online settings
The following describes how to configure the network connection of the centos 7 system in the vmwarevm.
Step 1: in VMware, click "edit"-"Virtual Network Editor". For example, I chose the NAT mode:
Click Change settings in the lower

found the network card can be online, and the network card has been sharing the Internet, so the VM shared host IP address Internet.
Noun explanation VM: The virtual machine is now embodied in a product called Vm/esa, which is widely installed in IBM's host operating system, including the MVS and Session Monitoring System (CMS), so each operating system looks like it has its own complete software and hardw
Description1) The VMware ESXi virtualization platform also supports this online extended disk feature.2) The KVM virtual machine also supports the online extended disk function, which is extended to a specific usage environment, primarily for production environments that cannot be deactivated.3) Tested KVM Online Exten
1. Technical Overview:Starting with Windows Server R2, administrators can use Hyper-V to extend or compress the size of a virtual hard disk while running a virtual machine. Storage administrators can avoid costly downtime by performing maintenance operations on a running virtual hard disk. You no longer need to shut down virt

SummarizeAs we can see from the previous introduction, even without shared storage, we can implement a non-disruptive dynamic migration of virtual machines, but there is a need for fast network support between all compute nodes. There are also two points to keep in mind:

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 than or equal to 0.12.1 (centos6.7 or above is OK)
Rpm-qa|grep qemu
