In virtualized systems, the setup of provided resources differs depending on how the system is implemented. Also, resource changes might or might not require temporary stoppage of a logical partition. If a logical partition needs to be stopped, this should not affect much because PFM - Agent for Platform is also stopped. However, if a logical partition does not need to be stopped, and the system resources change dynamically, the performance data obtained by PFM - Agent for Platform might be significantly affected. In this case, we recommend that you collect performance data not significantly affected by dynamic resource changes.

The following table shows the resources that can be collected for each virtualized system.

Table 2-2 Resources for each virtualized system

Virtualized system	Resource
	Processor count	Memory	Disk	Network
Zone	--	--	TS	--
PowerVM	DS	DS	TS	TS
HP Integrity Virtual Machines (I-VM)	TS	TS	TS	TS
VMware/KVM	TS	TS	TS	TS
Virtage	TS	TS	--	TS
WPAR	DS	DS	DS	--

Legend:

DS: Dynamic change is possible.

TS: The logical partition needs to be temporarily stopped.

--: Not supported
