Hi Chris, Actually, the system does not belong to us therefore we only had the log file. But it seems reasonable that besides the size of ephemeral diisk in _base, we also have the image of vm downloaded from Glance that consumes the disk capacity. That can make the strange value of disk_over_commit.
I will check this situation later. Btw, thank you for your help.

Just a thought...did you clear out the _base directory between tests? Or is there maybe an extra backing file sitting there consuming space?
