 NVMe drives as pass-through devices
To preserve the existing RAID configuration on the DGX-2 System and simplify the
process of reusing this resource if the server were ever to be reverted from KVM,
NVMe drives cannot be used as pass-through devices.
 The DGX-2 KVM host cannot be used to run deep learning containers with GPUs.
 NVIDIA GPUDirect
TM
is not supported on multi-GPU guest VMs over InfiniBand.
11.1.2 About the Guest GPU VM (Features and
Limitations)
 Guest GPU VMs are based on an installed KVM image.
 Guest GPU VM size and resources are based on the number of GPUs assigned
 Once a GPU VM is created and resources assigned, reconfiguring the VM (adding or
removing GPUs, modifying other resource allocations) is not supported.
 Access to the hardware is restricted from within the guest GPU VM such that
● GPUs cannot be reset
● GPU VBIOS cannot be updated
● System firmware (including Mellanox IB) upgrade is not supported
● There is no guest UEFI BIOS support
11.1.3 About nvidia-vm
Guest GPU VMs can be managed using the virsh (see https://linux.die.net/man/1/virsh)
program or using libvirt-based XML templates. For the NVIDIA KVM, NVIDIA has
taken the most common virsh options and configuration steps and incorporated them
into the tool nvidia-vm, provided with the DGX KVM package. nvidia-vm simplifies
the process of creating guest GPU VMs and allocating resources. In addition, you can
use nvidia-vm to modify default options to suit your needs for the VM and manage
VM images installed on the system.
