Bug ID 21077731
Issue: Oracle VM 3.3.x and 3.4.1 do not support the Intel Virtualization Technology for directed I/O (VT-d) and Single Root I/O Virtualization (SR-IOV) BIOS options. These options are enabled by default in the system BIOS settings.
Affected software: Oracle VM 3.3.x and 3.4.1
Workaround: Disable VT-d and SR-IOV before installing Oracle VM 3.3.x or 3.4.1.
From the BIOS Setup Utility main menu:
Navigate to IO → IO Virtualization.
Disable VT-d and SR-IOV.
