ora today to colleagues looked at Tencent cloud above problems from the start simply looked at the database of the hardware configuration is as follows:

Manufacturers buy servers are custom-CPU KVM do not know the problem or other problems so is actually very pit
The same configuration of a PC machine I am here for:
