Hi,
=20
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-kv=
m/
=20
Those two hooks will configure the kvm module properly and allow
dhcp/pxe to be used from within the nested VM.
Yes. Though it=E2=80=99s likely not going to work out of the box anyway =
due to older kernel.
See a guide from Ladi[1], there was also a presentation about nested =
hyper-v on KVMForum 2017=20
Thanks,
michal
