configure nova openstack with XenServer

I have successfully configured my XenServer environment to run DevStack. I decided to switch to a production environment. I configured a controller node on XenServer and a compute node (para virtualized vm hosted on Xen).
The dashboard is showing that provisioned VMs are created on the compute node. The compute node is hosting those VMs, unlike DevStack which provisioned VMs on XenServer directly. How can i configure nova service to use XCP ? i already followed the docs ( with no luck. here is my nova.conf file

rpc_backend = rabbit
rabbit_host = controller
  rabbit_password = ***************
  auth_strategy = keystone
   my_ip = *****************
  vnc_enabled = False
   vncserver_listen =
   vncserver_proxyclient_address = *************
 novncproxy_base_url = http://**********:6080/vnc_auto.html
  compute_driver = xenapi.XenAPIDriver
 network_api_class =

 firewall_driver = nova.virt.libvirt.firewall.IptablesFirewallDriver

 allow_same_net_traffic = False
 multi_host = True
send_arp_for_ha = True
share_dhcp_address = True

Could this just be a display issue? I see that you say that the _dashboard_ claims that the VMs are starting on the compute VM rather than the xenserver host - however if the nova service that you're running really is using the XenAPI driver then that nova service should not be physically able to start a server on the compute VM.

I assume you've checked actually where the VM is running? Does XAPI show the VM as started on the XenServer host? (either xe vm-list or with XenServer?)

Indeed after i changed virt_type=xenserver , it was attempting to creates VMs on the Xen host. I just had to run my compute node in PV mode

HI I am running openstack on ubuntu with devstack and now I want ot add a xen server compute node. From your thread it looks you have already done this.Could you please share any reference to achieve the same.
