Re: Problem enabling IOMMU with Buster and Xen

   I love how the various BIOS entries have zero help even though AMI has an 
empty help/description field. No, that was not enabled -- thanks! -- but even 
enabling it, doing a cold/poweroff boot cycle does nothing. It still gives the 
exact same error message.

   I actually haven't tried that. All of the various Xen "docs"/how-tos I've 
read say that each preceding step must be done or it won't work. (Based on 
your input, I'll try that but I'm not hopeful.)

   At this point I've read that Xen's passthrough might not work with some 
motherboard chipsets, so I'm wondering if Xen is a bit too cutting edge for 
what I want to do.

   What I want to do is to run multiple secure/separated VMs on a machine. One 
of those VMs will be to handle an Internet connection and firewall. Another VM 
will do filesharing via NFS and Samba; another VM is to run Kodi and output 
videos/TV via HDMI to a TV/monitor.

   From everything I've read, Xen is the ideal choice -- but only if I can get 
it to run. :)
