Reboot hanging: Windows Server 2003 guest on Windows Server 2012 R2 host

[clearth]

Since some versions of VirtualBox I can never reboot my Windows Server 2003 guest on my Windows Server 2012 R2 host. (Earlier versions of VirtualBox crashed at the end of shut down, more earlier versions didn't have any problems.) With version 4.3.10 and 4.3.8 (and earlier?) the VM gets hanging after I choose reboot. I have then to choose Machine > Close... Later I can restart the machine using VirtualBox Manager. The Windows guest system doesn't detect any errors reported in the Windows event logs. I have disabled some energy saving BIOS options on the host. In VirtualBox I have not allowed any options, that boost hard disk IO speed. The Windows operating systems of the host is configurated to avoid energy savings. I have two other VMs on this Windows Server 2012 R2 host, both are Windows Server 2008 R2 VMs and have no problems. I will answer all further questions, that you VirtualBox developers would ask me.

The problem is very annoying to handle with every Windows-Update, that is necessary. So I hope, you can help and VirtualBox gets more stable.

The VM, that is hanging while reboot, has two hard disk images, one for the system and one for the data.

The two hard disk images, the .vbox file of the VM and the logs directory of the VM are on the same host hard disk. This host hard disk is a fast server hard disk, that only has the function to host this one VM.

This could be related to #12406. At least it is the same effect.

Please reopen if still relevant with a recent VirtualBox release.
