[Qemu-discuss] question about qemu debug xv6 operation system kernal.

[krishnaLee]

Hi,
here I find some QEMU-build in commands:
https://pdos.csail.mit.edu/6.828/2017/labguide.html


I had install default qemu at ubuntu16.04 ,(qemu 2.5.0 monitor),I enter debug 
mode like this:
qemu-system-i386 -hda obj/kern/kernel.img -monitor stdio -gdb tcp::26000 -D 
qemu.log


after enter QEMU-monitor,I run " info pg ",it show "unknown command...",why? is 
that command has removed from qemu?
is there right command to show the page-table?


thank you.
