The error message seems very clear to me: no such host pipe exists. What makes you think that it should? I.e., which host application is creating a named pipe called 'MYVM'? It seems an unlikely name for typical host app to use. Site Moderator Posts: 29847 Joined: 4. Sep 2008, 17:09 Primary OS: MS Windows 10 VBox Version: PUEL Guest OSses: Mostly XP.
No, that would be wrong, at least as far as my understanding goes.Some application on your host will create a named pipe - this has to exist beforehand, just like a physical serial port has to exist beforehand if you want to use that. VirtualBox, on behalf of the VM, opens the pipe as a client, not a server.
Looks like I was wrong, or at least only half right. The manual mentions a server mode too (which somehow I don't remember reading about before), in which case the pipe is named along the lines you chose. If the 'Connect to existing pipe/socket' checkbox is ticked in the VM settings then you operate in client mode, unticked means server end.
However 'MYVM' would still be wrong unless that really is the name you gave to your VM. But if you want the VM to be a server, what is the client?If you want to continue this conversation then please provide a VM log file. With the VM fully shut down, right click it in GUI. Select 'Show Log' and save 'VBox.log' (ONLY) to a zip file.

Hi again,This is something that intrigue me and i want to understand why i get the error of VERRFILENOTFOUND. I have been able to setup a pipe tunnel without the need of third party software before and now im getting this error which i do not know where is coming from.I have attached a log and a picture of my VM serial port settings.BTW - MYVM is not the real name of my vm as you can see from the logs, the real name is ASA842 and the pipe is.pipeASA842, according to vbox documentation the pipe can be called whatever you want.

So, what else on your host creates that pipe?If another software is using this PIPE, and if i rename the PIPE i dont understand why im unable to connect through it and keep getting the same error.
I think this is a problem with Vbox that is not able to create the PIPE and that is what i read from the log file.'

Virtualbox Serial Port Not Working
Opening an existing pipe, not creating a new one.The Windows file open function is called CreateFile, and the same function is used for opening existing files as well as creating new ones, so you shouldn't read any significance into the 'Createxxxxxx' name.If two entities are to communicate via a named pipe, one side has to create it and act as a server, listening for requests. The other side opens an existing pipe, this is the client. The client will get an error of 'File Not Found' if it attempts to open a named pipe that hasn't been created yet, i.e. If the client is started before the server. This is what you are seeing.I'll ask one last time, then I'm afraid I have to give up. Which host application are you expecting will have created a pipe with this name?
Where and what is the server? Site Moderator Posts: 29847 Joined: 4. Sep 2008, 17:09 Primary OS: MS Windows 10 VBox Version: PUEL Guest OSses: Mostly XP.
VirtualBox Serial Debugging on WindowsThis tutorial uses VirtualBox version 4.2.6. You can set Port Mode as either Host Pipe Mode or Raw File Mode when serial debugging with VirtualBox.With Raw File Mode, you can easily and quickly save the debugged onto a.txt file whereas it might be rather difficult for to check out the content of debugging real time. When it comes to Host Pipe Mode, it’s a little more complicated than the Raw File Mode, but you can confirm what is being debugged real time. The results made by the two modes differ little from each other, so we recommend you employ a relatively simpler way: Raw File Mode. Serial Debugging using a Raw File1. Run VirtualBox.
Free download for pc games. Select your haiku image then click settings.Select Serial ports. Tick the tickbox 'Enable Serial port'. Change Port Mode to 'Raw File'.Then set the name and directory of the file to be saved in File Path.And click start (virtual machine) or double click your Haiku image.2. Once you open the file on the designated path, you can make sure it has been debugged.

Serial Debugging using Host pipe HyperTerminal and VMWareGateway Method.First of all, you need vmwaregateway.exe (you can find that ) Move the downloaded file to the directory you want.Start Command Prompt by pressing Win+ R and enter “cmd”. Then drag and drop vmwaregateway.exe onto cmd with the mouse. Then add “/t” before pushing the Enter button on your keyboard.C:Documents and Settingsme'C:wherevmwaregatewayisvmwaregateway.exe' /ttest mode - press Ctrl+ c to stop program. Run HyperTerminal.
If your OS is Windows XP, you can find it here: StartProgramsAccessoriesCommunicationsHyperTerminalHowever if you are running Windows vista, Windows 7, and Windows 8, then sadly HyperTerminal is not included as a bundled application like XP had. These later versions of windows do have software we can use, but it is not at all user friendly, rather you should just download HyperTerminal from and follow the directions given. If you run HyperTerminal, it will ask you to create a new connection, pick a name and icon. Click OK.After it will ask you what you are connecting with, change it to “ TCP/IP(winsock)“Change the host address to “localhost” and change the port number to “ 567”, click OK again.If it can’t connect, vmwaregateway.exe isn’t running in Command Prompt properly.Command Prompt should now read: C:Documents and SettingsmeC:Documents and Settingsme'C:wherevmwaregatewayisvmwaregateway.exe' /ttest mode - press Ctrl+ c to stop program incoming telnet request accepted. Run Virtualbox. Select your Haiku image then click settings.Select Serial ports.
While this formula may seem like the absolute answer because it involves numbers, math and a bit of homework, it doesn’t mean you’re stuck with the number you get as a result. Size chart snowboard.
Tick the tickbox “ Enable Serial port” and for Port Number tick “ COM1”(Because Haiku by default writes debug information to the COM1 port)Change Port mode to “ host pipe” and change the port path to:.pipevmwaredebug and click OKWhen you start your VM, it will now be debugging onto HyperTerminal.PuTTY MethodA simpler way is to use PuTTY Telnet, which can read VirtualBox’s fake serial port pipe directly without the need for vmwaregateway.exe. You can get Putty from the author’s site atThe trick is to use Serial mode, and replace the COM1 with.pipevmwaredebug or whatever you called the pipe in the VirtualBox serial settings. There are additional serial settings near the end of the preferences where you can set the baud rate to 115200, turn off handshaking and use 8N1 bits.Then fire up VirtualBox, and once it is running your VM, the pipe will exist and you can start up PuTTY.
Configure HaikuIf you are to control the output port and speed, you should do it with Haiku.Run Haiku on VirtualBoxOpen the file /boot/home/config/settings/kernel/drivers/kernel. To revise Output Port,#serialdebugport numTurn “num” into any figure you want. Default setting is 0 (COM1). To change Transmission speed,#serialdebugspeed valuesChange values.

I have two apps which communicate over a named pipe (Unix domain socket) - all on one machine. I cannot figure out how to get the app in the VirtualBox VM (Linux) to open the named pipe on the host (Centos7).I have mounted the shared folder so the Linux VM can see the shared folder containing the named pipe 'file'. But when it tries to connect to it, it gets ECONNREFUSED (no one listening).The only thing I could see in the VirtualBox Manager was a section on setting Serial Ports to point to named pipes. But I want my app in the VM to connect to the actual named pipe, not COM1.Is this possible?
