Viewing and Configuring OS Partition Settings

You can use either the Basic tab or the Advanced tab of the NI Real-Time Hypervisor Manager to view and configure hardware partition settings for an NI Real-Time Hypervisor system. Use the Basic tab if you do not need to assign specific devices to specific card slots or PCI interrupt request lines (PIRQs). Use the Advanced tab if you need to assign specific devices to specific card slots or manually resolve PIRQ conflicts.

Using the Basic Tab

If you do not need to assign specific devices to specific card slots or PIRQs, complete the following steps to partition the hardware devices in a Real-Time Hypervisor system using the Basic tab of the NI Real-Time Hypervisor Manager.

1. From Windows, select Start»National Instruments»NI Real-Time Hypervisor»NI Real-Time Hypervisor Manager to launch the NI Real-Time Hypervisor Manager.
2. Double-click the Memory row to display the Set Memory Configuration dialog box.
3. Review the amount of memory allocated to each operating system. If necessary, change the amount of memory allocated to each operating system to reflect your application requirements.
4. Click the OK button to keep the memory allocation settings you configured or click the Cancel button to revert any changes you made.
5. For every device in the Devices column, review the corresponding partition setting in the OS column. If necessary, change the OS partition settings to reflect your application requirements.

   Note  Some configurations are unavailable because of NI Real-Time Hypervisor system requirements.

6. Click the Apply button to automatically resolve PIRQ conflicts and apply the current configuration. When you apply the configuration, the NI Real-Time Hypervisor Manager generates a set of instructions.
7. Follow the instructions generated by the NI Real-Time Hypervisor Manager to ensure that each device is connected to the correct card slot.

Using the Advanced Tab

If you need to assign specific devices to specific card slots or PIRQs, complete the following steps to partition the hardware devices in a Real-Time Hypervisor system using the Advanced tab of the NI Real-Time Hypervisor Manager.

1. From Windows, select Start»National Instruments»NI Real-Time Hypervisor»NI Real-Time Hypervisor Manager to launch the NI Real-Time Hypervisor Manager.
2. Click Advanced to display the Advanced tab.
3. Double-click the Memory row to display the Set Memory Configuration dialog box.
4. Review the amount of memory allocated to each operating system. If necessary, change the amount of memory allocated to each operating system to reflect your application requirements.
5. Click the OK button to keep the memory allocation settings you configured or click the Cancel button to revert any changes you made.
6. For every device in the Devices column, review the corresponding partition setting in the OS column. If necessary, change the OS partition settings to reflect your application requirements.

   Note  Some configurations are unavailable because of NI Real-Time Hypervisor system requirements.

7. For every hardware device under a PXI chassis, review the corresponding PIRQ assignments in the PCI Interrupt column and make a note of which cards include a warning icon next to the PCI Interrupt assignment. The warning icon indicates a PIRQ conflict, which occurs when a device shares a PIRQ line with another device that is assigned to a different operating system, contrary to the NI Real-Time Hypervisor system requirements.
8. Resolve all PIRQ conflicts using one or more of the following methods.
   • Click and drag the conflicting devices to different card slots to ensure that cards assigned to different operating systems do not share PCI interrupt request lines (PIRQs).
   • Change the OS assignments of one or more conflicting devices.
   • Select File»Auto Resolve to automatically resolve PIRQ conflicts. The Auto Resolve operation resolves conflicts by changing only card slot assignments while leaving the current OS assignments unchanged.
9. Click the Apply button to apply the current configuration. When you apply the configuration, the NI Real-Time Hypervisor Manager generates a set of instructions.
10. Follow the instructions generated by the NI Real-Time Hypervisor Manager to ensure that each device is connected to the correct card slot.
