All the time we do in the virtualization will do one thing is P2V, and very few people do v2p, in fact, we may encounter this situation, as the reason is conceivable, nothing but performance is not satisfied, can not operate in the virtualized platform, although this situation is very rare, but there will still exist, So here we talk about v2p of those things, v2p
Preface
System migration refers to moving the operating system and applications on the source host to the target host and running properly on the target host. In the era when there is no virtual machine, the migration between physical machines relies on system backup and recovery technologies. Back up the operating system and application status on the source host in real time, connect the storage media to the target host, and restore the system on the target host. With the development of virtual

DTSi, similar to the C-Language header file. The other machine correspond to. DTS to include this. DTSi. For example, for vexpress, Vexpress-v2m.dtsi is referenced by Vexpress-v2p-ca9.dts, Vexpress-v2p-ca9.dts h

In Linux, We can compile the devicetree file separately. When we run makedtbs in the Linux kernel, If we select arch_vexpress before, the

migrates the workload from one physical machine to another. p2v migrates the workload of one physical machine to a virtualization platform; v2V and v2p migrate virtual machines from one virtualization platform to another through the network, or migrate workload from one virtual machine to one physical machine. After understanding the two-way, automated, and policy-based migration between P, V, and I, it is easy to understand the virtualization-bas
currently only used in extremely high-end Power channels, such as Intel's P4 CPU. If FPGA has a latch unit, the Register unit can be configured as a latch unit. In the Xilinx v2p manual, the Unit can be configured as a register/LATCH unit. The attachment is the structure of Xilinx half slice.
The general design rule is to avoid latch in most designs. It will make the timing sequence of your design end, and its concealment is very strong, it cannot be
I. What to do (Major): familiar with Vmware, especially the network functions of VMware, and using VMware as a USB-based boot system.
Ii. Yesterday and earlier foundations:
1. Build the Internet between the virtual system and the real system (do not know this should be called v2p, V-LINK-TO-P ?)
2. Streamline the gho file of the XP system to over 300 MB, and mount the USB flash disk with the thunder, opera, and FTP servers Through vmware and ghost.

Note: We plan to migrate the oeltest01 VM in the source kvm host to the target VM. The principle is to directly copy the VM disk files and configuration files to the target VM. The key point is that the source and target virtual hosts must use a storage pool to configure Virtual Machin
efficiency, errors, and even unplanned capital costs, increasing the cost of virtualization.
Chris Wolf, a senior analyst at the Burton Group, believes that an enterprise may find that the first half of the year of virtualization migration may not know what virtualization is. "In the end, they may have to invest money in management software ." Management plans and budgets are often the key factors for successful virtualization.
