[ovirt-users] Turn on "Nested Virtualization" on the "hosted-engine"

[Martin Sivak]

Hi,

it might be a good idea to install vdsm-hooks-nestedvt and
vdsm-hook-macspoof on the host as described for example here:
https://community.redhat.com/blog/2013/08/testing-ovirt-3-3-with-nested-kvm/

Those two hooks will configure the kvm module properly and allow
dhcp/pxe to be used from within the nested VM.

Best regards
