when we start a vm, we call JOB_MASK(QEMU_JOB_NONE), then 1 << -1 will be execute.
we fix it as return 0

This makes QEMU_JOB_NONE and QEMU_JOB_QUERY to have the same result.
I think you need to fix some other place.
What is the problem you are seeing?

1、JOB_MASK(QEMU_JOB_NONE) = 0; JOB_MASK(QEMU_JOB_QUERY) = 1;
2、It isn't a question, but it looked awkward.

Could you point us to the place in our code where JOB_MASK is called on
QEMU_JOB_NONE?
