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
Nested virt is largely outside the scope of this list, it's at a much
deeper level than virt-manager. First step is to run newest kernel you
can get your hands on in L0 and L1. Next would be to try something other
than VirtualBox in L1. If you hit issues at that point you can try
reporting on kvm mailing list
