你好
我对获得VM内存转储的可能性有兴趣进一步分析（进程，套接字，其他工件列表）。如果使用KVM虚拟机管理程序（acropolis），如何进行。

我需要在正在运行的VM上创建转储以进行分析。需要对过程的详细描述。如果我理解正确，Nutanix中的所有VM都以文件的形式保存，哪些文件是VM转储文件？Qualanix是否具有创建和下载虚拟机​​的完整伪文件的特殊程序？
操作系统没关系，它可以是任何东西。

请告诉我要了解这个问题的信息。

In AHV another concept is used for storing data and it doesn\u2019t store it in files like ESXi does.\u00a0<\/p>

To create a memory dump you will need to force a VM to crash. There is no such feature to suspend a VM, so you will need to crash it and then reboot it. For Windows VM that can be done by doing an NMI dump (VM will go to blue screen, then write a dump, then will reboot)\u00a0and on Linux by running the \u201csend-key\u201d command. In both situations VM will be crashed and the memory dump will be generated. The dumps will then be available in the guest VM. Both procedures are described in details in the KBs that i linked above.<\/p>","className":"post__content__best_answer"}">

Hello
I am interested in the possibility to get a VM memory dump for further analysis (list of processes, sockets, other artifacts). How to do it if using the KVM hypervisor (Acropolis).

I need to create a dump on a running VM for analysis.\u00a0A detailed description of the procedure is required. If I understand correctly, all VMs in Nutanix\u00a0are kept in the form of files, which files are VM dump files? \u041er does Nutanix have a special procedure for creating and downloading a complete dummy file(s) of a virtual machine?
OS doesn't matter, it can be anything.

Please tell me the information to understand this issue.<\/p>","quoteUsername":"Vladimir13","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

也许，这些文章可能有用：

对于Windows VM：https://portal.nutanix.com/page/documents/kbs/details?targetid=ka03200000099a4caa.

对于Linux VM：https://portal.nutanix.com/page/documents/kbs/details?targetid=ka00e000000cwc9cak.

是的，我找到了类似的程序。谢谢。
我是否正确理解，创建内存转储的过程将为在正常模式下工作的VM工作，并且不挂起？

在Internet I符合信息中，要在VMware中保存VM的转储，我可以暂停VM的工作，然后下载直接文件* .vmss

.vmss.

.vmss

这是暂停状态文件，存储暂停虚拟机的状态


也许在AHV中，有类似VMware中的功能，暂停VM和下载RAM转储文件？

也许你能给我这个信息如何用VM的所有文件打开文件夹并下载它们？
谢谢你。

Yes, I have found similar procedures. Thanks you.
Did I understand correctly that the procedure for creating a memory dump will work for a VM that works in normal mode and does not hang?

In the internet i met information, that to save dump of a VM in the VMware, I can suspend work of the VM and then download direct file *.vmss<\/p>
\t\t\t

.vmss<\/p>\t\t\t<\/td>\t\t\t

\t\t\t

<vmname>.vmss<\/p>\t\t\t<\/td>\t\t\t

\t\t\t

This is the suspended state file, which stores the state of a suspended virtual machine<\/p>\t\t\t<\/td>\t\t<\/tr><\/tbody><\/table>


Maybe in the AHV there is feature like as in the VMware, pause a VM and and download ram dump file?
\u00a0<\/p>

and maybe can you give me the information how can i open the folder with all files of a VM and download them?
Thank you.<\/p>","quoteUsername":"Vladimir13","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

在AHV中，另一个概念用于存储数据，它不会将其存储在ESXi等文件中。

要创建内存转储，您需要强制VM崩溃。没有这样的功能可以暂停VM，因此您需要崩溃，然后重新启动它。对于可以通过执行NMI转储完成的Windows VM（VM将转到Blue屏幕，然后通过运行“发送键”命令来编写转储，然后重新启动）和Linux上。在两个情况下，VM将崩溃，将生成内存转储。然后转储将在Guest VM中使用。这两种过程都在上面链接的KBS中描述了。

我想我想出来了。谢谢您的帮助。
我会向客户提供这些信息，我希望这些信息和他将关闭这个问题。

I think I figured it out. Thanks for the help.
I will give this information to the customer, I hope this information and he will close the question.<\/p>","quoteUsername":"Vladimir13","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

我试图为VM Windows制作转储文件，该文件是创建的。一切都是工作。

但是，也许有没有标准过程从ACLI和ACLI下载转储文件创建VM Memory的转储文件而不进入VM？
还是没有这种可能性？:)

据我所知，现在在AHV中没有这种可能性。转储文件只能从VM中获取。

As far as i know, there is no such possibility in AHV now. The dump files can only be acquired from inside the VMs.<\/p>","quoteUsername":"Sergei Ivanov","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
