In this blog we want to explore using NVIDIA GPU Direct RDMA with OpenShift Virtualization. The question is why would we want to do so? Sometimes there might be some legacy applications that cannot run inside a container and therefore will need to run on a virtual machine. These virtual machines will most likely run on Openshift given it has the capability to do both container and virtual machine workloads. This unified environment makes management of IT infrastructure efficient because customers are not managing disparate systems for their various workloads.
Assumptions
We assume we already have a OpenShift cluster running with some kind of backend storage and OpenShift Virtualization installed. In our example environment we have 3 control planes and 3 worker nodes. The worker nodes have Mellanox BF3's and NVIDIA A40 GPUs. We are using OpenShift Data Foundation as the backing storage where needed and it is useful when live migration is a requirement. With the assumptions covered we can begin configuring the system for GPU Direct RDMA.
Enable Device PassThrough
Before we can consume the devices in a virtual machine we need to enable device passthrough on the workers nodes for the Mellanox cards and the GPU devices so they can be used directly by the virtual machines. First we need to enable intel_iommu and can do so by creating the following MachineConfig.
$ cat <<EOF > 100-worker-iommu.yaml
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:
labels:
machineconfiguration.openshift.io/role: worker
name: 100-worker-iommu
spec:
config:
ignition:
version: 3.2.0
kernelArguments:
- intel_iommu=on
EOF
Next we will create a butane file that contains the vendor/pci ids of the devices we wish to bind to vfio which enables them for passthrough.
$ cat <<EOF > 100-worker-vfiopci.bu
variant: openshift
version: 4.16.0
metadata:
name: 100-worker-vfiopci
labels:
machineconfiguration.openshift.io/role: worker
storage:
files:
- path: /etc/modprobe.d/vfio.conf
mode: 0644
overwrite: true
contents:
inline: |
options vfio-pci ids=10de:2235,10de:145a,15b3:a2dc,15b3:c2d5,15b3:1021,15b3:0237,15b3:0016
- path: /etc/modules-load.d/vfio-pci.conf
mode: 0644
overwrite: true
contents:
inline: vfio-pci
EOF
After building the butane file above we can pass it through the butane command to generate the corresponding custom resource file.
$ butane 100-worker-vfiopci.bu -o 100-worker-vfiopci.yaml
Next we need to generate a mlx_core blacklist so the driver does not load on the worker node. We do not need to do this for the GPU drivers because by default the nouveau driver is blacklisted in OpenShift.
$ cat <<EOF > 99-machine-config-blacklist-mlx5_core.yaml
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:
labels:
machineconfiguration.openshift.io/role: worker
name: 99-worker-blacklist-mlx5-core
spec:
kernelArguments:
- "module_blacklist=mlx5_core"
EOF
With the MachineConfigs generated we can go ahead and create them on the cluster.
$ oc create -f 100-worker-iommu.yaml
$ oc create -f 100-worker-vfiopci.yaml
$ oc create -f 99-machine-config-blacklist-mlx5_core.yaml
One by one the nodes will reboot as the MachineConfigs are applied to them. Wait for all the worker nodes in the cluster to reboot before proceeding and confirm with the output of the oc get mcp command.
$ oc get mcp
NAME CONFIG UPDATED UPDATING DEGRADED MACHINECOUNT READYMACHINECOUNT UPDATEDMACHINECOUNT DEGRADEDMACHINECOUNT AGE
master rendered-master-08f7504a24cb5e9734f3cfe995db08c6 True False False 3 3 3 0 122d
worker rendered-worker-8c3ff0c3b0d16b30f7eb76992fd7d3b1 True False False 3 3 3 0 122d
Once confirmed we can proceed to the next section about exposing the devices to OpenShift.
Expose Devices to OpenShift
Now that devices have been configured for passthrough we need to expose them to the kubevirt-hyperconverged configuration. We can do this by editing that configuration.
$ oc edit hyperconverged kubevirt-hyperconverged -n openshift-cnv
Once we are in edit mode we can add our devices. Our environment example looks like the following below where we have A40 GPUs, Mellanox CX7s and Mellanox BF3s. The resourceName is arbitrary after the nvidia.com portion. Since both BF3 and CX7 cards show up as CX7 when looking at them via lspci I decided to put the BF3 prefix on the ones from a BF3 card so I could tell the difference. Another thing to note is that this setup should really have consistently configured cards in the workers. What I mean is that the cards should either be set for ethernet ports or infiniband ports as there is no way I could tell the difference.

Once the lines are added we can save and exit the edit command. We can use the following command to check that they are properly showing. Note some of my nodes has BF3 cards and some just had vanilla CX7 cards.

If everything looks good we can proceed to launching our virtual machines.
Launch Virtual Machines
We need to launch a few virtual machines in order to test GPUDirect RDMA with our passthrough devices. The virtual machine custom resource files will look something like the examples below though they could be different depending on what one plans to test and what workloads will run inside the vm. We will need two virtual machines running on different compute nodes so we ensure each yaml has a defined nodeSelector. Note in these examples we are referencing one of the Mellnox devices and one of the NVIDIA GPU devices. The first machine is defined below.

Once we have generated the virtual machine custom resource files we can create them on the cluster.
$ oc create -f rhel9-rdma1.yaml
$ oc create -f rhel9-rdma2.yaml
We can validate they are running by using oc get vmi.
$ oc get vmi

If everything looks good we can proceed to configuring the NVIDIA drivers on the virtual machines.
Prepare for NVIDIA DOCA and GPU Drivers
Now that our virtual machines are up and running we will need to configure the NVIDIA DOCA and GPU drivers to take advantage of the devices we have passed up to them.
$ oc get vmi

We can use virtctl to access the console of the virtual machines and login.
$ virtctl console rhel9-rdma1

Next we need to enable the CodeReady repository.
$ sudo subscription-manager repos --enable=codeready-builder-for-rhel-9-x86_64-rpms
Repository 'codeready-builder-for-rhel-9-x86_64-rpms' is enabled for this system.
For NVIDIA's drivers there are dependencies to EPEL so we will need to enable that repository as well.

After adding the required repositories we also need to make sure the nouveau driver is properly blacklisted. To do this we will need to edit the default grub file.
$ sudo vi /etc/default/grub
We just want to append the modprobe.blacklist=nouveau on the GRUB_CMDLINE_LINUX line like the example below.
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"

GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true
We also need to create two denylist.conf files under /etc/modprobe.d.
$ sudo echo "blacklist nouveau" > /etc/modprobe.d/denylist.conf
$ sudo echo "options nouveau modeset=0" >> /etc/modprobe.d/denylist.conf
Finally we can rebuild the dracut image and generate the new grub file.
$ sudo dracut --force
$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg

Build Perftest with CUDA Libraries
Now we can move onto building perftest binaries by first cloning the repository.
$ git clone https://github.com/linux-rdma/perftest.git
Cloning into 'perftest'...er]# git clone https://github.com/linux-rdma/perftest.git

Next we need to export our paths for the CUDA libraries.
$ export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
$ export LIBRARY_PATH=/usr/local/cuda/lib64:$LIBRARY_PATH
~
Now we can change directories into the perftest project and run autogen.sh.
$ cd ./perftest
$ ./autogen.sh

Next we can find our eth1 interface.
$ nmcli con show

We will bring down the interface.
$ nmcli con down "Wired connection 1"
Connection 'Wired connection 1' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3)
Modofy the interface to add static ipaddress and mtu of 9000.
$ nmcli con modify "Wired connection 1" ipv4.method manual ipv4.addresses 192.168.12.2/24 mtu 9000
Then bring the interface back up.
$ nmcli con up "Wired connection 1"
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4)
This completes setting up the network connectivity inside the virtual machines.
Run Performance Tests
Now that we have configured our virtual machines with all the requirements we can run some tests to confirm that GPUDirect RDMA is working properly. To do this we will use the perftest tooling we built and run the ib_write_bw command. This will require that we open two console sessions into each virtual machine. The first consolse session we will run the listener ib_write_bw command and in the second we will run the initiator. In the first VM we will run the following command.
$ sudo /home/cloud-user/perftest/ib_write_bw -R -T 41 -s 65536 -F -x 3 -m 4096 --report_gbits -q 16 -D 60 -d mlx5_0 -p 10000 --source_ip 192.168.12.1
WARNING: BW peak won't be measured in this run.
Perftest doesn't supports CUDA tests with inline messages: inline size set to 0

The second VM should have the following command.
$ sudo /home/cloud-user/perftest/ib_write_bw -R -T 41 -s 65536 -F -x 3 -m 4096 --report_gbits -q 16 -D 60 -d mlx5_0 -p 10000 --source_ip 192.168.12.2 192.168.12.1
If we go back to the first VMs console screen we should see output similar to the results of our run below.

Next we can run another test in our corresponding virtual machines where in the first one we add the following switches to our original command --use_cuda=0 --use_cuda_dmabuf. This will ensure we are now testing with GPU and using DMA-BUF. Note that DMA-BUF is now preferred over using nvidia-peermem module. The first VM should have the following command.
$ sudo /home/cloud-user/perftest/ib_write_bw -R -T 41 -s 65536 -F -x 3 -m 4096 --report_gbits -q 16 -D 60 -d mlx5_0 -p 10000 --source_ip 192.168.12.1 --use_cuda=0 --use_cuda_dmabuf
