Algorithm 2: Integrated VM consolidation.
1:	Input: hostList Output: scheduleMap
2:	for each: host in hostList do
3:	if LR(host) is overloaded then
4:	while host is overloaded do
5:	VM ← MMT(host)
6:	migrationList.add(VM)
7:	end while
8:	end if
9:	end for
10:	scheduleMap.add(RUA(migrationList))
11:	Obtain candidateHostSet from hostList
12:	for each: host selected from candidateHostSet do
13:	if PA(host) is underloaded then
14:	if RUA(host.getVmList()) succeeds then
15:	scheduleMap.add(RUA(host.getVmList()))
16:	Switch the host to sleep mode
17:	end if
18:	end if
19:	end for
20:	return scheduleMap
