I did a fresh installation on FreeBSD 10.4-RELEASE-p5 amd64 GENERIC.

Whenever I need to stop the VM it hangs indefinitely. The OS in VM is
also FreeBSD 10.4-p5 amd64. Virtual machine runs fine, but if is use
shutdown -r now, shutdown -p now (in VM) or use ACPI PowerOff in
phpVirtualBox or VBoxManage it always hangs after OS in VM is completely
down (buffers synced etc.)

Packages used:
     virtualbox-ose-kmod-5.2.0_1
     virtualbox-ose-nox11-5.2.0_1

Built with Options        :
           PYTHON         : off
           R0LOGGING      : off
           UDPTUNNEL      : on
           VDE            : on
           VNC            : on
           WEBSERVICE     : on


     The process is still running:

# ps auxww | grep FBSD_104_tpl
vboxusers 1268   0.0  5.3 1062960 891668  -  I    11:30PM   0:32.43
/usr/local/lib/virtualbox/VBoxHeadless --comment FBSD_104_tpl --startvm
ba50a283-41fa-48ae-8ff2-87591c50bfed --vrde config

# VBoxManage list vms
"FBSD_104_tpl" {ba50a283-41fa-48ae-8ff2-87591c50bfed}

      but no running VMs listed by VBoxManage

# VBoxManage list runningvms

# VBoxManage controlvm "FBSD_104_tpl" poweroff
VBoxManage: error: The virtual machine is being powered down
VBoxManage: error: Details: code VBOX_E_INVALID_VM_STATE (0x80bb0002),
component ConsoleWrap, interface IConsole, callee nsISupports
VBoxManage: error: Context: "PowerDown(progress.asOutParam())" at line
578 of file VBoxManageControlVM.cpp

The above is the second try to stop VM after few minutes of waiting on
"Stopping" in phpVirtualBox.

It must be killed by "kill PID", then I can run the VM again.
(phpVirtualBox says "Aborted")


Can anybody help me to debug and fix this issues?

I never see this problem on different machines with slightly older
version of VirtualBox. We are using the same setup for years.

What are the chances that you're VNC'ed to the VM during shutdown?  I've
yet to gather all the parts but there is a bug in libvncserver/vbox that
fails to allow a VM to quit if the VNC session isn't closed before the
the VM is shutdown.

Thank you! You saved me a lot of time.
Yes, this is the problem. When VNC is connected, the VM cannot be shut
down. If I disconnect VNC then shutdown works fine.
It is really annoying bug but at least I know a workaround now.
Thank you.

Do you know if this bug is reported somewhere?

Kind Regards

I haven't reported to Oracle yet and I don't see anything in their bug
tracker.  Maybe this weekend I'll try to get more information for the
bug.

Just in case if you want to follow along. It appears that vbox DEBUG is
broken and I think that might give us some more hints on to what's
happening here but for the time being I can't find that much more
information about this issue.

Thank you for your report. I am on Christmas vacation, I will check it later.
