Thanks Erik firstly for your response, I seems have high probability to hit this issue now.
Is there any workaround solution?

Thanks!

Sounds like this one:
https://gitlab.com/qemu-project/qemu/-/issues/933

so it may we worth following up with it. If it's the same issue (from your
description it sure looks like it) then it is a race condition in the IDE
emulation in QEMU and we had to disable an upstream integration test in libvirt
for the suite to stop failing :(.
