Do the two days of testing,,, found that may be the method to solve the problem:
1. Set the virtual machine name in English, because I started out as a Chinese, use the second method, didn't work, then set it to English, can say 100% success rate,
VirtualKD 2. Open, open the virtual machine, will not succeed the first time, on the virtual machine, and restart the virtual machine, the second open opportunity found VirtualKD reset into 1, wait a minute, this time, it becomes more than 2 or 2, or you will be successful, manually open the windbg basic manual open windbg, the attributes can also be more than 2 or 2,
In addition, I can debug is cloning a good snapshot of the virtual machine, so set up a named pipe,
Conclusion: big probability related to reset this property, and can analyze
