It seems, there is an issue on HPE G8 servers with the below ESXi versions:

  1. ESXi 5.5 Patch 10
  2. ESXi 6.0 Patch 4
  3. ESXi 6.5

Intel® IOMMU’s (aka VT-d) interrupt remapper functionality has been changed in the above versions and you need to enable it manually:


  • Run this command:

    esxcli system settings kernel set –setting=iovDisableIR -v FALSE

  • Reboot the ESXi host.
  • Ensure the iovDisableIR setting is set to FALSE with this command:

    esxcli system settings kernel list -o iovDisableIR

    For example:

    esxcli system settings kernel list -o iovDisableIR

    Name          Type  Description                                 Configured  Runtime  Default
    ————  —-  —————————————     ———-  ——-  ——-
    iovDisableIR  Bool  Disable Interrupt Routing in the IOMMU…   FALSE       FALSE    TRUE

Oracle Software Collections 2.3

The Software Collections library allows you to install and use several different versions of the same software at the same time on a system.  Software collections are primarily intended for development environments.  These environments often require more recent versions of software components such as Perl, PHP, or Python to access to the latest features.  However, they also need to avoid the risk of disrupting processes on the system that rely on different versions of these components.

You use the software collection library utility (scl) to run the developer tools from the software collections that you have installed. The scl utility isolates the effects of running these tools from other versions of the same software utilities that you have installed.
