This document explains how to debug a guests' kernel using KGDB.
|
|
|
|
1. Run the guest:
|
|
'kvm run -k [vmlinuz] -p "kgdboc=ttyS1 kgdbwait" --tty 1'
|
|
|
|
And see which PTY got assigned to ttyS1 (you'll see:
|
|
' Info: Assigned terminal 1 to pty /dev/pts/X').
|
|
|
|
2. Run GDB on the host:
|
|
'gdb [vmlinuz]'
|
|
|
|
3. Connect to the guest (from within GDB):
|
|
'target remote /dev/pty/X'
|
|
|
|
4. Start debugging! (enter 'continue' to continue boot).
