we’ve got an ESX guest server running Windows Server 2016 with an Nvidia Tesla M60 in compute mode attached as a PCI device.
This is all running fine without any issues.
The guest server has 256GB memory.
When I increase the guest server memory to 320GB, and re-check the ‘Reserve all guest memory’ option the server won’t start - I get the error messages ‘Failed to register the device pciPassthru0 for 5:0.0 due to unavailable hardware or software support.’ and ‘Module ‘DevicePowerOn’ power on failed.’
Has anyone got any ideas on what I can do to fix this please?
