6.7 Edit the bitfusion-server-2 virtual machine hardware settings
Follow the steps:
1. Under the Virtual Hardware tab, Verify the number of vCPUs is 8
• Minimum No. of vCPUs = 4x No. of GPU devices attached to the appliance. In this case, 4 x 2 GPUs
i.e. 8
2. Verify the memory is set to 48GB and select the checkbox Reserve all guest memory.
• Minimum GB of memory = 1.5x aggregate total of GPU memory on all GPU cards passed through. In
this case, 1.5x 32GB i.e. 48GB
3. Click on Add New Device and add two PCIe devices. Select the PCI devices from the drop-down
menu.
• 0000:86:00.0 | GV100GL V100 SXM2 16GB

6. Under the Virtual Machine Options tab, select Advanced > Configuration parameters and then select
Edit Configuration. Edit the pciPassthru.64bitMMIOSizeGB parameter to 64.
• pciPassthru.64bitMMIOSizeGB= <n>, where n equals (num-cards * size-of-card-in-GB) rounded up to
NEXT power of 2. In this case, 2x 16 → 32, rounded to next power of 2 i.e. 64
7. Refrain from powering on the virtual machine. Click on Enable Bitfusion from the bitfusion-server-2
