People mentioned about long-term operations' LOCKs there. It seems that, in libxl_driver, certain opeations may hold a lock for too long, thus other operations, even those just do query jobs, would be blocked.
In qemu_driver, there seems to be a more complexy way to solve this problem, by employing a condition variable.
Yep, that's pretty much the approach we'd want to take for libxl too I believe.
My question is : Is "Fixing such problem in libxl_driver" in our todo-list?
Yes
If yes, what's the detailed solution? Will that be similar to qemu's CONDITION VARIABLE method?
