In my case the problem is quite subtle.
Nearly every time we send the key strokes, the guest os keeps receiving space
or tab or new line character. And ending part of the text is truncated, where
the truncated part is fixed depending on the keystrokes we are sending.
Additionally, the keystroke
Public bug reported:
Whenever capslock is pressed on host, both capslock keycode(0x3a 0xba)
and capslock LED keycode(0xfa 0xfa) would be sent to the ps2 keycode
stream.
However, capslock LED is handled by another thread, confirmed by tracing
`ps2_write_keyboard` with gdb. The keycode of casplock
### Reproduce steps
Add `fprintf(stderr, "ps2_queue 0x%x\n", b);` to `hw/input/ps2.c` and
re-build qemu.
- qemu-system-x86_64 -hda --enable-kvm -m <> -display vnc=:1
- vncviewer -Shared :5901
In guest os, find the keyboard device(very likely to be /dev/input/event0)

NUMA: move numa related code to n
Add hmp command set-mem-policy to set host memory policy for a guest
NUMA node. Then we can also set node's memory policy using
the monitor command like:
(qemu) set-mem-policy 0 policy=membind,relative=false,host-nodes=0-1
