Sure. This approach is similar to what live CDs do, and a number of VM servers support this natively with no extra work on your part (e.g., VMWare GSX).
Of course, because the VM still needs space to write files (because the guest OS will need to write files even if your application doesn't), you're going to pay a hefty price in memory. Essentially the pieces of the VM that need to be written to must be offloaded to main memory, which reduces the memory available to the rest of the applications you have.

您可以将虚拟机映像放入 DVD 中吗？
可以
您可以在 DVD 中（内部）运行虚拟机吗？
可能不能，因为虚拟机本身需要 RAM 的写入权限文件之类的东西。
Can you put a vm image into a DVD?
Yes
Can you run the vm whithin (inside) the DVD?
Probably not, because the vm itself will need write permission for RAM files and things like that.
当然。这种方法类似于 Live CD 的做法，并且许多的 VM 服务器本身就支持此功能，而无需您进行额外的工作（例如，VMWare GSX）。
当然，由于虚拟机仍然需要空间来写入文件（因为即使您的应用程序不需要，来宾操作系统也需要写入文件），因此您将在内存方面付出高昂的代价。本质上，需要写入的虚拟机部分必须卸载到主内存，这会减少可供其他应用程序使用的内存。
