WinDbg WinDbg is one of a number of tools that can be used for debugging Windows guests in XenServer environments. You can get QEMU to passive-open a TCP port on dom0 for serial output and wait for a connection, this method will work if you're running on a machine with a dynamically assigned IP address: on XenServer 6.2 or later xe vm-param-add uuid= param-name=platform hvm_serial=tcp::,server,nodelay on earlier versions xe vm-param-add uuid= param-name=other-config hvm_serial=tcp::,server,nodelay Then: • Grab a copy of HW Virtual Serial Port from and install it.

Serial Port pass-through to domU. To make your xenserver into a serial. This will create a com port in your virtual machine that is routed. Debugging Windows Guests on XenServer. You can get QEMU to passive-open a TCP port on dom0 for serial output. Dtsoft Virtual Cdrom Device Driver on this page. On XenServer 6.2 or later. Xe vm-param-add.

• Fire up the application and configure a COM port to point at your dom0 IP address and the you specified to QEMU above). Make sure that you uncheck 'NVT Enable' in the Settings tab. • Start the COM port.

• Configure debugging inside the guest by editing boot.ini in the usual way. • Reboot the VM. • Start windbg and point it at the COM port you created.

An Unofficial Method To the best of my knowledge we have never released sockpipe.exe but this is a method some of our own developers use, it isn't supported but may be useful to developers in a debug scenario. If you're running windbg on a machine with a statically assigned IP address then you can use the following setting to get QEMU to active-open a TCP port on your machine for serial output: on XenServer 6.2 or later xe vm-param-add uuid= param-name=platform hvm_serial=tcp:: on earlier versions xe vm-param-add uuid= param-name=other-config hvm_serial=tcp:: Then: • Run sockpipe.exe (which seems to be available ) on the machine where you want to run windbg. Run it without arguments to get help; it should be fairly obvious what's going on.

For example, you could use 'sockpipe ' (where is the name number as specified to QEMU above). • Fire up windbg and go ``File->Kernel Debugging', make sure that ``Pipe' is ticked, and enter. Pipe in the Port box, where is the pipe name specified to sockpipe. • Configure debugging inside the guest by editing boot.ini in the usual way. • Reboot the VM. • Debug as normal. I'm told it may be a bit slow, but it mostly works although it has limitations; it will not work for SMP 64 bit or SMP Vista.

I know Xen didn't use to do it, but I was also under the impression that it had been on the 'it's coming' list for so long that it must be there by now. Vmware and virtualbox have had serial and usb pass through for a while. It's only now that I'm looking at how I'm going to build a server for a customer next week, that I've discovered this thread, and I'm disappointed to see that it's still not there, and it sounds like it's still low priority and a long way off, if at all. I've managed to do the fiddle with the iSCSI driver to get windows guests to access a tape on the host and other fiddles with 'network' USB servers to get a windows guess to be able to see a USB security dongle on the host is there some other ('network'?) method of allowing a windows (sbs) or linux (hylfax) guest to be able to see a 9600 baud fax modem on a serial port? One of the critical questions about the Serial Port native integration is the necessity in the Industrial Automation process or even in little RS-232 controllers apps hosted inside the XenServer.
