Hello Chenfu,

Thank you for posting your inquiry on the NVIDIA Developer Forum - Infrastructure and Networking - Section.

Yes, vDPA over VirtIO Full Emulation is supported for BF2. Chapter 5 of the “NVIDIA DOCA Emulated Devices” describes this → https://docs.nvidia.com/doca/sdk/pdf/emulated-devices.pdf

Thank you and regards,
~NVIDIA Networking Technical Support

We conducted testing by following the steps in the documentation to set up the environment and encountered two issues:

  1. When we set the number of VM network card queues to more than 15, QEMU fails to start and logs the message “you are asking more queues than supported: 15.”
  2. After starting the VM, it appears that the VM’s packet reception performance is only around 1.6Mpps, and when receiving packets at around 1 Mpps, the VM begins to experience packet loss.

Are these two issues reasonable?
