Hi,
I have a HP server running Windows 2012 R2 + Hyper-V. On this server, four VM have Windows Server 2003 R2, and one VM has Windows 2012. After power outage, 1 2003 R2 VM and 1 2012 VM are started properly, but the other three machines aren't. I've started it manually. All VM's have last version of Hyper-V integration tools installed, the option "Automatically start VM if it was running before the service was stopped" was chosen. I'm not very familiar with Hyper-V, so, I've investigated only Hyper-V-VMMS event log. There are some recurring errors:
The Integration Services Setup Disk image could not be updated: The process cannot access the file because it is being used by another process. (0x80070020).
and
Failed to get the disk information.
But I think it isn't a clue.
How can I clarify, why these machines aren't started automatically?
