A method for testing computing hardware detects the current time as being within a predetermined time period and transfers virtual machines (VMs) from a plurality of physical machines to other physical machines as targets according to a load balancing strategy. The load balancing strategy sums of a load ratio of one physical machine including the VM and a load ratio of one physical machine as a target for the transfer; if the sum of the two ratios is less than a preset load ratio, the VM-transferring physical machine is put into a standby state when the transfer takes place as long as the current time is still inside the predetermined time period. Physical machines which are in the standby state and have not been tested are awoken, and the awoken physical machines are connected to the server for testing.
