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. krishna
