OK, so the title needs a little explanation:)
I have Xubuntu 16.04.5 LTS installed in my workstation. In there I have installed virt-manager, libvirt, qemu etc. to run a CentOS 7.5 VM as another hypervisor using nested virtualization; this VM works.
What does not work however is inside of the CentOS VM installing virt-manager, libvirt, qemu, etc. and run another VM inside of that. Trying to start a CentOS VM inside my L1 CentOS hypervisor kernel panics very soon after grub with a backtrace like this:

However, using the exact same procedure is successfull using an Xubuntu 18.04 as L0 instead!
So, to simplify:
Xubuntu 16.04 -> CentOS 7.5.1804 -> CentOS 7.5.1804 = Kernel panic
Xubuntu 18.04 -> CentOS 7.5.1804 -> CentOS 7.5.1804 = Success!
Please know if there´s any more information you need!
Thanks in advance!
