Subject [general][signal] I encountered some signals when debugging VM
Date Mon, 29 Oct 2007 11:26:38 GMT
The gdb trace is like this below, and it seems happen when creating VM.
I am curious, Where do they come from and what is major task of them ?
BTW. Can I block these signal when debugging VM?

Starting program:
