Under the vm advanced options, under host. You chose a specific host then allow passthrough or pinning.

Thanks.  The Installation->Reinstall was something I missed but that doesn't seem to have helped.  The host info still says that 'Device Passthrough' is Disabled. I'm sure I enabled everything I needed to in the BIOS but will have to double check.  This is an old motherboard without IPMI though.  Meh.

In order  to change a kernel parameter  - set the host into maintenance -> edit the host -> kernel ->  put  ticks where necessary or type your kernel parameter and save.
Next use the 'Installation'  dropdown and select reinstall.
Once  it's over - reboot the host from UI.


At least this is the way I have enabled  nested virtualization.
