[SPDK] NVMF target in the virtualbox

[SPDK] NVMF target in the virtualbox

Hello

Is there a way to use the NVMf target while running SPDK inside virtualbox.
I do not know if there is a RDMA NIC in DPDK. Could not find anything while
googling it.

Thanks
Sumit

SPDK currently uses the ibverbs/rdmacm directly, so whatever the kernel provides as the rdma device is used. Personally I have not tried DPDK devices.

Does DPDK's IB framework uses the kernel IB framework ? I am very new to
DPDK but my understanding is that DPDK does not use any of the kernel
networking frameworks. Softiwarp or Softroce register with kernel IB
frameworks so they probably wont work with DPDK/SPDK.

I tried Softiwarp with SPDK and was able to get the target to start, but I couldn't get the Linux initiator to work with it.

You need some kind of RDMA device in order to run NVMe-oF currently, whether it is real or virtual. I’ve seen some mention of a Soft-RoCE driver added to the Linux kernel in 4.8 (linux/drivers/infiniband/sw/rxe/rxe.h). That would probably work too, but I’ve never used it.

Hi Benjamin

I could not find any RDMA NIC for virtualbox (dont have any real NICs, trying on my laptop). That too we need a NIC which is supported by DPDK. Are you aware of any ? Or is there a loopback mode which can be used to play with NVMf target on spdk ?

I’m not particularly familiar with the capabilities of virtualbox, unfortunately. I do know that QEMU can emulate at least an NVMe SSD and SPDK will load and run against that.

You’d need virtualbox to emulate an RDMA NIC, or you’d need to map a real RDMA NIC directly into the VM. The same goes for the NVMe SSD. You don’t need any RDMA support from DPDK itself.
