No, all I'm saying is that this case hasn't been considered so far.

Nested isn't unusual. What's unusual is that you want a device
surfaced to a 2nd level guest that's being exposed by the host
hypervisor rather than the L1 guest one. Whether that's valid to
be done in a secure manner may need some thought, and
definitely will need code to be added afaict.

Hi Jan,Â

Thanks for your help. We've turned off the HYPERV options off and we can see the

disks again, we're going to run with this for now.Â

Unfortunately I've ran into another issue with the DomUs hanging early at boot

under this setup but I will open another thread for this.Â

Thanks,Â

Mark
