Hi All,
I've just installed Qubes 4.0.1 on a brand new Dell Latitude 5590 (Intel
i5/8250U, with 16GB RAM) using the downloaded ISO burnt to a UBS stick
prepared on a Windows machine with Rufus (partition scheme GPT target
system UEFI).
I've booted the new machine on UEFI mode and the firmware Virtualization
settings all enabled (there are 3 parameters here: "Virtualization",
which is I suppose is VT-x, "VT for Direct I/O", which I suppose stands
for VT-d and "Trusted Execution").
When I issue lscpu command on dom0 I get "Virtualization type: none".
What's wrong? Why I do not see virtualization on dom0? I run a Windows
HVM, which confirms Virtualization (VT-x) is available. But what about
VT-d? Isnt it available for isolation purposes?
Dom0 is basically a VM running on top of Xen, so all it's reporting is
the emulated CPU (to over-simplify things a bit). In order to get the
actual values, ask Xen directly with "xl info". You can also run
"qubes-hcl-report".
