Mark Russinovich, founder and former Chief Software Architect at Sysinternals/Winternals and now Microsoft Technical Fellow has released version 5.0 of the SysInternals LiveKd tool.
LiveKd is a utility which allows you to enable kernel debuggers like Windbg and Kd, part of the Debugging Tools for Windows on a local system. Normally these tools only work when attaching a serial “null modem” cable between two systems and booting the to be analyzed system into debugging mode.
Version 5.0 of the LiveKd tool allows you to use the tool remotely on a virtual machine, without installing the software locally on that machine, but running the tool on a Hyper-V host. By providing this functionality, you can debug VMs which are unresponsive or have issues which prevent you from even installing LiveKd on that system.
The tool can also be started from the web, coming from the live.sysinternals.com website, where the other Sysinternals tools can be found as well.
