[dpdk-users] DPDK VIRTIO on Google cloud platform (GCP)

[Prabhuram K]

Hi,
I am trying to run DPDK inside GCP and internally it uses virtio with 3
queues. But on loading, it throws error telling only one queue is
supported.
I am running DPDK 19.11.

EAL: PCI device 0000:00:05.0 on NUMA socket -1

EAL:   Invalid NUMA socket, default to 0
EAL:   probe driver: 1af4:1000 net_virtio
EAL: PCI device 0000:00:06.0 on NUMA socket -1
EAL:   Invalid NUMA socket, default to 0
EAL:   probe driver: 1af4:1000 net_virtio


*Ethdev port_id=0 nb_rx_queues=3 > 1*


Anyone has similar issues? How to enable multi-queue in google cloud ?

I am using e2-custom (4 vCPUs, 5.5 GB memory).


Any specific machine types to be used for multi-queue in GCP?


Any help is highly appreciated.


Thanks,

Prabhu

Looks like GCP (host side) only supports a single queue.
GCP has their own custom implementation of virtio.
Virtio supports negotiating the number of queues between host and guest.
Not a DPDK problem.
