Is it possible to run esxi v5.5 under oVirt 3.5, i.e. nested virtualization?

I don't know about ESXi 5.5, but I was just recently able to run Hyper-V under oVirt. Look for my thread on "Hyper-V in a guest". I did have to reboot the host for the module parameters to take effect when all was said and done.

Basically, you install 'vdsm-nestedvt' on your hosts. It should be in the repos for your distro, if you are running CentOS6 or above.

Once installed, reboot your host, as there is a parameter that needs to get passed to the kvm_* module when it loads to allow nested KVM.

Once you have rebooted, go to your Hosts tab and look in :Host Hooks"; you should see something like this:

before_vm_start 50_nestedvt

You probably need also the macspoof hook if you want to have properly working network connectivity for your L2 VMs:

I hope this helps.

Alan
