ubuntu 14.04下bochs或者gdb调试Pintos

bochs调试：

galaxy@galaxy-virtual-machine:~/pintos/src/threads/build$ ../../utils/pintos -- run alarm-multiple

gdb调试：

首先bochs要支持远程gdb调试

galaxy@galaxy-virtual-machine:~$ cd bochs-2.6.6
galaxy@galaxy-virtual-machine:~/bochs-2.6.6$ ./configure --with-x --with-x11 --with-term --with-nogui --enable-debugger --enable-gdb-stub
00000000000i[      ] reading configuration from bochsrc.txt
