Virtage functionality
Like other virtualized systems, the functionality provided by Virtage includes the following:
- Virtual networks
- Virtual processors
- Virtual memory
Virtage manages the above functionality to implement a virtualized system. The logical partition must be stopped to change the virtual network or virtual memory, or to change the number of assigned virtual processors. The logical partition does not need to be stopped to change the virtual processor assignment percentages.
Virtage configuration
Like VMware, Virtage has a parent/child configuration.
To set up a virtualized system on Virtage:
- Start the installed instance of Virtage.
- Create and set up a virtual machine.
- Start the virtual machine.
Using PFM - Agent for Platform on Virtage
Keep the following in mind when using PFM - Agent for Platform on Virtage.
- Installing PFM - Agent for Platform
- Because Virtage is configured in a special environment called an SVP frame, do not install PFM - Agent for Platform on an SVP frame.
- Processor information
- Because a virtualized system based on Virtage runs after the logical partition is set up, the number of processors is not changed while PFM - Agent for Platform is running. Accordingly, operation can be performed as usual, but the number of allocated processors might not match the number of processors that physically exist.
- Memory
- Because a virtualized system based on Virtage runs after the logical partition is set up, the amount of memory is not changed while PFM - Agent for Platform is running. Accordingly, operation can be performed as usual.
- Devices
- Disk performance data is only for logical partition groups. System-wide performance data that includes the host OS cannot be collected. For the network adapter information, information about network adapters allocated to the guest OS is obtained.
