Hello. Nested virtualization lags and it have many errors for me.
I have a Host (L0) with libvirt(virt-manager) I have there a VM (L1) and I
want to run in L1 a Virtual Box machine (L2). But I get errors while
installing Windows in L2. Windows installed and it was ready for 1st boot
and i got a VirtualBox error when I started it. Linux distributions
doesn't boot in graphical install and live mode is not booting, I got lot
of text and it's stucked. Virtual Box Version is 5.2.
I created /etc/modprobe.d/kvm_intel.conf with text in it
options kvm-intel nested=Y
and VMX is running in L1
I think I got errors because of some graphical/video issues. Here are few
of my L1 settings
<cpu mode='host-passthrough'/>
<graphics type='spice'>
<listen type='none'/>
<gl enable='no'/>
</graphics>
<video>
<model type='virtio' heads='1' primary='yes'/>
</video>
also I tried to use
<video>
<model type='qxl' ram='65536' vram='65536' vgamem='1048576'
heads='1' pri$
</video>
I'm using nouveau drivers
if it's needed I can post full logs of VirtualBox error and full XML
configuration file for VM that I use in virt-manager.
Maybe I need to change VirtualBox in L1 to another virtualization software ?
OS
L0 - Debian
L1 - Debian
L2 - can't install any OS
