If runtime compiler (JIT) is supported, the VM needs to do JIT related initialization, including initializing the compilation policy, compiler back end, code cache, etc.
如果支持运行时编译，CVM需要做JIT的相关初始化，包括初始化编辑策略，编译器后端，代码缓存等等。
The authors chose richness of features over minimalism, making it easy to code and build compilers for the Parrot VM.

The object code for a VM is also called bytecode, specifically defining an instruction set that an interpreter executes.
VM的对象代码也称为bytecode，特别定义解释程序执行的一个指令集。
Such as when the VM executes code in kernel mode; then VMWare has to carefully translate the memory mapping and permissions in order to simulate the VM's virtual CPU correctly.
比如，当VM以内核模式执行代码时；为了正确地仿真VM的虚拟cpu,VMWare必须谨慎地转换内存映射和权限。
Also, the Mono VM only accepts raw source so no "pre-compiled".net code can be inserted.
不但如此，Mono虚拟机目前还只能够接受原始的源代码，而经过“预编译”的。NET代码则无法执行。
On the technical side, Blue Ruby is using parse tree to produce BRIL code (ABAP VM bytecode). Blue Ruby takes care of security using a bridge and a virtual file system.
从技术的角度看，BlueRuby用parsetree来生成BRIL代码(ABAPVM的字节码)，用桥和虚拟文件系统来保证安全。
In order for hot code fixing to work, you need to launch your runtime workbench with -xj9 in your VM arguments of the Command Line Settings, as shown in Figure 6.
如图6所示，为了使紧急修复的代码工作，您需要启动运行时工作台，并在CommandLineSettings中为VMarguments输入- Xj9。
VM size and class libraries have been reduced to a standard of 50 to 80 KB of object code.
VM的大小和类库已减小为50到80KB目标代码的标准。
Compiles all Ruby code into instructions (op_codes) which the shotgun VM runs - currently with a.
将所有的Ruby代码转换成shotgun虚拟机所执行的指令(op _ codes)——目前通过op _ code解释器执行。
For VM arguments, enter the code shown in Figure 61 by pasting the code provided in c: \ RCPEJBClient \ Snippet1.txt (Listing 9).
对于VMarguments，通过C： \RCPEJBClient \Snippet1 . txt所提供的代码(清单9)输入如图61所示代码。
Listing 12 shows the sample code demonstrating how to register and start a vm using vmware-cmd; Listing 13 shows the sample code demonstrating how to register and start a vm using vmrun.
清单12显示了演示如何使用vmware - cmd注册和启动vm的样例代码；清单13显示了演示如何使用vmrun注册和启动vm的样例代码？
The following code snippet (from kvm-12/user/main.c) provides a high-level peek into starting a VM (see Listing 1).
下面的代码片断（来自于kvm-12/user/main.c）从较高的层次上查看了VM 的启动（请参见清单1）。
Requiring explicit reference management when the native code wants to keep handles to VM objects between JNI calls.
当原生代码需要在JNI调用之间保存VM对象的句柄，需要显式引用管理。
Rubinius, a Ruby implementation that currently also uses userspace threading, recently added MVM support. With this code vm = Rubinius::VM.spawn
Rubinius是一个Ruby实现，它现在也在使用用户空间线程，最近它还增加了多虚拟机支持 。
The O-code could be interpreted on a physical machine (as a VM) or compiled from O-code to the native machine language of the host.
O-code可在物理机上解译（为VM），或从 O-code编译为主机的本机语言。
To avoid the chicken-and-egg question "How can a ruby VM work if it's parser is ruby code?" : during the build process of the Rubinius VM, the ruby source code of ruby_parser can be compiled into.
为了避免这个问题，在Rubinius的虚拟器中，ruby _ parser的Ruby源代码会被编译为Rubinius字节码。当Rubinius启动时，它通过读取ruby _ parser的字节码文件——这些文件不需要进行语法分析——来运行一个ruby语法分析器。
You will see that VM protection can effectively prevent code analysis, it is one of the most powerful protection systems.
可以看出，虚拟机加密是目前强度最高的保护方式之一，可以有效阻止代码还原及分析。
