Hi Simone,
sorry for the late comment (I just found this thread while researching on nested oVirt-on-VMware issues).

It seems that the problem is generally known and has been solved upstream in kernel 4.16:


Any ETA on backports in RHEL7? ;-)
(Note: should I open a Bugzilla on kernel package for this?)

Ciao Giuseppe,
Thanks for the accurate report.
Honestly I'm not aware of backport ETA but I'd suggest to file a bug on product: Red Hat Enterprise Linux 7, component kernel, subcomponent KVM pointing to the upstream patch.
Not sure if we are still on time for RHEL 7.6.
I seems that Hyper-V would experience the same troubles and I think that making nested-inside-Windows-host work should be deemed fairly important for demo/trial/lab uses... :-)

In the meanwhile, workarounds have been published for the new Ansible-based setup flow:


on the other side, I can confirm that with the legacy setup flow (with option --noansible) adding the following to the answer file avoids the problem (did not test whether newer types like pc-i440fx-rhel7.2.0 solve it too):


Many thanks.

Best regards,

Hi Simone:
   Yes, it's in a nested environment.  L0 is vmware esxi 5.5.

I know for sue that a nested kvm env over vmware esxi is still problematic; kvm over kvm works fine instead.
