I found upstream codes conflict with COLO and lead to crash,
and I located to this patch:
commit 386a907b37
Author: Wei Wang <wei.w.wang@intel.com>
Date: Tue Dec 11 16:24:49 2018 +0800
migration: use bitmap_mutex in migration_bitmap_clear_dirty
My colleague Wei's patch add bitmap_mutex in migration_bitmap_clear_dirty,
but COLO didn't initialize the bitmap_mutex. So we always get an error
when COLO start up. like that:
qemu-system-x86_64: util/qemu-thread-posix.c:64: qemu_mutex_lock_impl: Assertion `mutex->initialized' failed.
This patch add the bitmap_mutex initialize and destroy in COLO
lifecycle.
