Hi,

(my) question of the day: What happens to the KQEMU's shadow GDT and LDT
if the guest modifies their content (and not their locations) while QEMU
is running in emulator mode in userspace? I just enforced dt_changed=1
in update_dt_cache(), and this took me a few steps further in the
bring-up of our special guest OS under KQEMU.

In theory, this requires some flag in the kqemu_cpu_state to signal such
events down on KQEMU_EXEC - given userspace keeps track of all changes
already. Is there such a bit? Haven't looked into that details yet.
