When I was running a Fedora desktop and was doing a lot of dev/test work on VMs+Foreman+Puppet, I used Libvirt+QEMU as the VM hypervisor. I ran Foreman inside a CentOS VM, which talked to my desktop's Libvirtd to provision new VMs, hand out IPs via DHCP, boot via TFTP, then kickstart. It worked pretty well, and helped me to spin up a vcenter foreman controlled dev environment for a few hundred users in just a few days. My recommendation would be Vagrant + Libvirt.
