ESXi Troubleshooting

Changing from passthrough to non-passthrough devices fails to take effect after a reboot​

  1. Edit the /etc/vmware/esx.conf file by changing the owner of the PCI device from passthru to vmkernel.

    Example of the edit:

    Change from: /device/000:02.0/owner = "passthru"

    Change to: /device/000:02.0/owner = "vmkernel"

    Replace 000.02.0 with the PCI address of the device. You can it fro ESXi Dashboard.

  2. Reboot the ESXi host.

Note: for some reason if the line is not there, adding it does not work.
