It's very much possible, Devstack will install no problem on a KVM guest. The VM's you start up will be super slow (VM on top of a VM), but it will work.
If you really want to get fancy, you can install all of OpenStack on the KVM guest, except the nova-compute service, then install nova-compute on your hypervisor directly. Once you get that set up properly, your OpenStack VM's will boot along-side your KVM guest running OpenStack, directly on the hypervisor.
It should be possible, it is already done with for example VMware ESX and virtualbox. But then you need to install nova in combination with qemu. Because according to my knowledge it is not possible run virtualization software on top of virtualization software.
Theoretically, you can do that and Openstack should run without any error.
I have installed openstack taking ESXi as hypervisor. I suppose doing it on KVM is pretty easier as you might get a good documentation regarding it, so you can go for it.
If you are using it for a development/evaluation purpose, I would suggest you do that with virtualbox vm. It helps you with having KVM service running on the VM where you are installing it. If you are doing it on a VM in KVM, just check if KVM service (modprobe) on the vm is operational for you to create new VM.
