This cause me a big production problems, please help me. one virtual machine shutted down unexpectly. The Hype-v log shows: DM operation add for the virtual machine 'XXXXName' failed with error: Unspecified error (0x80004005) (Virtual machine ID 7EDDD39A-F963-4FAA-8854-6179B7611AC3).
could it be possible if nobody touch the Hype-v and DM error happened??? please tell me how to fix this problem.
DM is "dynamic memory". Your virtual machine tried to add memory and failed. A human didn't trigger this, you've just run out of memory.
Edit: the reason it failed, the error code, is explained here. It's possible there was a permission problem trying to allocate more memory. But still, essentially, you ran out of memory.
