VBoxManage: error: Error starting guest session (current status is: starting)

[rklehm]

After upgrade from 5.0.26 to 5.1.2 we can not use our automated run sequences controlled by several VBoxManage guestcontrol <vm> run commands, because some of them are returned with the error message:

VBoxManage: error: Error starting guest session (current status is: starting)

This seems to occur not at the first launch of a guestcontrol command after starting the VM, but at one of the following. For example one of such sequence is:

> VBoxManage snapshot ${VM} restore "${RestoreSnapshot}"
> VBoxManage  sharedfolder add ${VM} --name RunExecution --hostpath ${HostRunExecutionDirectory}/${BID} --automount
> VBoxManage startvm "${VM}"  --type headless
> VBoxManage guestproperty get "${VM}" "/VirtualBox/GuestInfo/Net/0/V4/IP"
> VBoxManage controlvm "${VM}" setvideomodehint 1920 1080 32
> VBoxManage guestcontrol ${VM} run --username ${VmUser} --password ${VmPassword} --wait-stdout -- \
  "c:\windows\system32\xcopy.exe" "${RunExecutionDirectory}\\runtime-uitest" "C:\\runtime-uitest\\" /r /y /s /i
('''failed''') > VBoxManage guestcontrol ${VM} run --no-wait-stdout --no-wait-stderr \
  --username ${VmUser} --password ${VmPassword} -- "C:\Windows\system32\cmd.exe" /c \
  "${RunExecutionDrive} & cd ${RunExecutionDirectory} & ${RunExecutable} /param:dummy=dummy "

Until solved we downgrade to 5.0.26.
