The guest OS cannot boot until the VM reflects a state of “running.” Hence, the problem is tied to the virtual machine’s configuration, not to the guest operating system. Remember, the error message indicates that Hyper-V is unable to change the virtual machine’s state. While it is true that guest operating system corruption can cause a boot failure, error messages like the one shown above occur before Hyper-V even tries to load the guest OS. The biggest mistake that I typically see admins make as they try to resolve the problem is that of assuming that the virtual hard disk is to blame. I have encountered this and similar error messages on real-world, production systems on a few occasions. Upon doing so I received the error message shown below. This morning, for example, I tried to boot a previously healthy virtual machine that I hadn’t used in a few months. Other times, however, Hyper-V does not give you any information regarding the error’s underlying cause. If, for example, the VM is asking for more memory than what the Hyper-V host can provide, then you will receive an error message like the one shown below. When a virtual machine fails to start, the underlying cause is usually obvious. In this article, I wanted to outline a few different potential causes and solutions in case you find yourself with a Hyper-V virtual machine that won’t start. Brien’s solution saved many IT admins from days of stress, and that’s why this article is one of our 20 Best of 2020.Īlthough Hyper-V is normally very reliable, I have on occasion run into situations in which a previously functioning VM refuses to start. In this tutorial from January, Brien offers answers for a perplexing problem: What to do when a Hyper-V virtual machine won’t start. One of the problems with Hyper-V is that it is usually so reliable, so when problems arise users are at a loss. Actual TDP may be lower if not all I/Os for chipsets are used.For our readers who use Microsoft Hyper-V - and there are a lot of them - Brien Posey’s advice, knowledge, and in-depth tutorials are indispensable. System and Maximum TDP is based on worst case scenarios. Please refer to the Launch Date for market availability.
