Practical Android skills: Switch JDK under Ubuntu After Android L, we recommend that you use JDK 7 to compile the program. This is a natural development rule, just like compiling Android 1.6 4 years ago and using JDK 5. Multi-version JDK can coexist. You only need to use the update-alternatives tool to switch between them at any time. The following describes how to install openjdk and oracle jdk (cannot cope with sun) and switch the version.1.

1. Preface Currently, we are engaged in cloud computing IAAs. virtualization is an important part of IAAs. Therefore, during this period, we have studied Virtual Machine technologies and tools. The purpose of this research is not only to use this tool, however, by studying and understanding the implementation mechanism and principles of technology, we need to know exactly what it means. This article is the beginning of my entry into this technology field. While recording my own progress, hope to

After processing packets in the Virtual Machine kernel, they reach the hypervisor through the vnic and then forward the packets to the vswitch (a bridge that provides communication between the virtual machine and the physical Nic adapter ). In the middle, this bridge needs to play the OVN tunnel function, encapsulate the packets from the virtual machine and forward them to the queue of the physical adapter. After the physical adapte
