I have Virtual Box setup with the following commands:

vboxmanage setextradata myVm "VBoxInternal/Devices/pcnet/0/LUN#0/Config/transfer/HostPort" 50000
vboxmanage setextradata myVm `"VBoxInternal/Devices/pcnet/0/LUN#0/Config/transfer/GuestPort" 50000
vboxmanage setextradata myVm "VBoxInternal/Devices/pcnet/0/LUN#0/Config/transfer/Protocol" TCP

On the host machine, the following command times out:

telnet localhost 50000

What am I doing wrong? The above command does work on the guest machine.

Shutting down and restarting the virtual machine fixed the problem.
