An Energy-Efficient Strategy and Secure VM Placement Algorithm in Cloud Computing

Algorithm 4

VMs free.

	Input: ACTH = {acth1, acth2, …, acthk} ⟶ Hosts which are in active state,
	ACTV = {actv11, actv12, …, actv21, actv22, …, actv2p} ⟶ VMs which are in active state.
	Output: ACTV Updated.
(1)	for each host in active state acthi ∈ ACTH then do
(2)	for each VM actvij ∈ acthi then do
(3)	if actvij in idle state then
(4)	Deallocate actvij resources to acthi
(5)	end if loop
(6)	end for loop
(7)	end for loop
