HPC PoC Lab on Azure platform - PXE node warewolf provisioning work around

I already have my Azure based HPC PoC and I am using warewolf provisioning tool. Come across an issue trying to set up PXE boot to provision nodes. Found out that azure does not support PXE boot on its virtual machines. I have read of work-arounds and one of them was to set up nested hyper-v VMs. Has anybody successfully done this ?
