Hello all!

I have a Openstack ambient with 5 components (Grizzly Version):

1 Xenserver 6.2 (top of list)
  - 1 cloud controller (ubuntu 12.04)
  - 1 network Quantum (ubuntu 12.04)
  - 1 compute with Qemu
  - 1 Compute Xen (nova-compute PV machine with Xenapi)

I can create instances with the compute qemu, but i cannot create instances with the Xen Hypervisor.

When I create a instance with the Xen compute I received the error below:

Hello,

I think that there is a mismatch between the nova plugins that you're using in dom0 and the nova code you're running in the DomU. So you need to update the content of /etc/xapi.d/plugins on dom0 according to the version you are running on the domU. On my installation I just copied the content of /opt/stack/nova/plugins/xenserver/xenapi/etc/xapi.d/plugins that is located on domU (I'm running devstack) to /etc/xapi.d/plugins that is located on dom0.

Hope this help,
Guillaume
