Hello,
We've been having an interesting issue with our Windows Server 2012 Host. There are currently 10 VMs running on Hyper-V with guest OSes ranging from Windows XP to Windows Server 2008 R2. The currently running machines are working fine. I can connect to them, access them via RDP and Hyper-V, ping them, etc.
The issue arises when I attempt to start any of the remaining three VMs that are currently off. The VMs are running Windows XP, Windows Server 2003, and Windows Server 2008 R2 (all operating systems that are working fine on the other VMs). When I attempt to start the machine, I get the following error before any startup screen can be displayed:
The application encountered an error while attempting to change the state of 'WEBSERVER1'
'WEBSERVER1' failed to start worker process: Incorrect function. (0x80070001).
I even tried to create a new VM, but I received the exact same error message when I tried to start the machine. Anyone ever experienced this type of error? My first guess was some sort of logical VM limit, but I can't test that just yet as there are several users in our office who are utilizing the running VMs. I'm afraid that if I shut down any of the running VMs, I may not be able to start the machine up again.
Also, I went and checked the event viewer and found three entries for each attempt at starting a VM:
Event 17040, Hyper-V Worker: The authorization store could not be initialized from storage location 'msxml://C:\ProgramData\Microsoft\Virtual Machine Manager\VmmHyperVAuthstore.xml'. Error: The system cannot find the path specified. (0x80070003).
Event 15500, Hyper-V-VMMS: 'WEBSERVER1' failed to start worker process: Incorrect function. (0x80070001). (Virtual machine ID 4F14787D-58C6-4F30-92A8-E491828B2518)
Event 15130, Hyper-V-VMMS: 'WEBSERVER1' failed to start. (Virtual machine ID 4F14787D-58C6-4F30-92A8-E491828B2518)
Any help will be greatly appreciated!!
