Hi,
What is the root cause of the below issue:
Failed to register the device pciPassthru0 for x:x.x due to unavailable hardware or software support.
We have Sun x4-8 server that the server had 768 GB memory, there was no problem but after upgrading memory to 1TB, the machines with pass-thru devices couldn't be start.
Two virtual machines are located on the server and the machines have one NIC and two HBA ports.
ESXi version: 6 U2
