The NativeEdge solution includes Device Passthrough to virtual machine capabilities such as USB, PCI-E, and GPU. In NativeEdge release 2.1.0.0, several issues were found in this functionality. 

Peripheral Component Interconnect Express (PCIe or PCI-E) is a serial expansion bus standard for connecting a system to one or more peripheral devices. If issues with setting up the PCI Device Passthrough are spotted, the following should be verified first:

  1. Verify PCI or PCI-E devices that were visible in NativeEdge Endpoint Peripherals
  2. Upload an application to catalog and enable PCI or PCI-E passthrough
  3. Deploy the application and add PCI or PCI-E device to deployment
  4. Deployment may stop responding for a long time, this is a symptom indicating a PCI or PCI-E passthrough issue
  5. After the Virtual Machine booting, any of the passed PCI devices are not observed

原因

Some of the PCI devices have sub-controllers (for example, USB controllers). NativeEdge endpoint devices handle and reconcile all PCI devices and sub-controllers during attachment to virtual machines. Some of the sub-controllers may have functional dependencies on each other. Hence, it causes undefined behavior when there is no special logic defined to sequence the handling of the controller during binding and unbinding operations.

解决方案

NativeEdge Engineering has created a dedicated hotfix to address the issues described above.

  • The hotfix only works if the NativeEdge environment is at version 2.1.0.0.

Contact Dell Support Services to allocate a hotfix bundle to fix the issue.

The following models of PCI devices are handled to treat this error in the latest hotfix bundle.

  • Sunix PUB0300XL
