I am trying to create a kilo test environment running on top of xen (controller, network, and compute are VMs). At this point I cannot have mutliple networks and I am planning to use 1 network for everything (management, compute, and etc) on neutron. I tried to find correct configuration for this type of environment but there is nothing on OpenStack docs site. I am wondering if anyone can provide some instructions. Unfortunately devstack does not meet my needs. I appreciate all the help in advance!

Do you mean Xen, or XenServer?

If XenServer, check out which gives a guide for using Mirantis OpenStack.

Many of those networks _do_ have to be isolated though - so if you want a setup with only one NIC and no access to VLANs then also check out which explains how you can use GRE tunnels to create fake networks for proof of concept environments.

To be honest i haven't setup openstack on top of xen , but my knowledge says you need to set up OpenVSwitch bridge and set br-ex as the ethernet interface.

You can create openstack with one interface also. Though it does not make any practical sense but I myself made such kind of setup just for development environment. I used devstack in ubuntu and packstack in Centos for it.

If you want more customization then you can always go for a manual installation guide. Here is the link :-

If you follow this guide the only thing you have to do it install all the packages that come on the single node. Configuration is exactly the same . It will also take very less time if you install in manually.
