As has often been the case, Microsoft has introduced a new gotcha this month in the cumulative update for Windows 7.
After installing this update, virtual machines (VM) may fail to restore successfully if the VM has been saved and restored once before. The error message is, “Failed to restore the virtual machine state: Cannot restore this virtual machine because the saved state data cannot be read. Delete the saved state data and then try to start the virtual machine. (0xC0370027).”
This affects AMD Bulldozer Family 15h, AMD Jaguar Family 16h, and AMD Puma Family 16h (second generation) microarchitectures.
Microsoft is aware of the issue and has set mid-February as a tentative time to see a fix.
Stay close, we’ll keep a watchful eye out and let you know when the fix is available.
