debugging Windows programs on XenServer

WinDbg

WINDBG is one of a number of tools available from Microsoft that can be used for debugging Windows guests in XenServer env Ironments.

You can get the QEMU to passive-open a TCP port in DOM0 for serial output and wait for a connection, the This method would work if You ' re running in a machine with a dynamically assigned IP address:
On XenServer 6.2 or later

Xe Vm-param-add uuid=<uuid> Param-name=platform Hvm_serial=tcp::<port>,server,nodelay

On earlier versions

Xe Vm-param-add uuid=<uuid> param-name=other-config Hvm_serial=tcp::<port>,server,nodelay

Then:

1. Grab a copy of HW Virtual Serial Port from http://www.hw-group.com/products/hw_vsp/hw_vsp2_en.html and install it .
2. Fire up the application and configure a COM port-to-point at your dom0 IP address and the <port> your specified to QE MU above). Make sure this uncheck ' NVT Enable ' in the Settings tab.
3. Start the COM port.
4. Configure debugging inside the guest by editing boot. Ini in the usual.
5. Reboot the VM.
6. Start WinDbg and point it at the COM port created.

An unofficial Method

To the best of my knowledge we had never released Sockpipe.exe but that's a method some of our own developers use, it's N ' t supported is useful to developers in a debug scenario.

If you ' re running WinDbg in 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=<uuid> Param-name=platform hvm_serial=tcp:<machine>:<port>

On earlier versions

Xe Vm-param-add uuid=<uuid> param-name=other-config hvm_serial=tcp:<machine>:<port>

Then:

1. Ru n Sockpipe.exe (which seems to is available here) on the machine where you want to run WinDbg. Run it without arguments to get help; It should is fairly obvious what's going on. For example, you could use ' Sockpipe <name> <port> ' (where <port> was the name number as specified to QEM U above).
2. fire up WinDbg and go "File->kernel debugging", make sure that "Pipe" is ticked, and enter \\.\pipe\<name> ; In the Port box, where <name> was the pipe name specified to Sockpipe. Hit OK.
3. Configure debugging inside the guest by editing boot. Ini in the usual.
4. Reboot the VM.
5. Debug as normal.

I ' M told it is a bit slow, but it mostly works although it had limitations; It won't work for SMP or SMP Vista.
