I thought it could be used for anything on the XenAPI side too, although I have not tried it that way yet. We have posted some docs on the XenAPI side. Around the pooled live migration that uses this anyway: https://review.openstack.org/#/c/13202/ Cheers, John From:

Hi, I suspect the problem is that your VM was unable to access the internet on the VM's interface specified by: HOST_IP_IFACE You can see how the Ubuntu install parameters are specified here: https://github.com/openstack-dev/devstack/blob/master/tools/xen/scripts/install_ubuntu_template.sh#L53

OK, so XCP-XAPI install is not that well documented yet. There is at least one manual step to make the XenAPI plugins work. What you need to run, on your Dom0 is this: sudo mkdir -p /usr/etc I think it is simply not present because it is Ubuntu and not CentOS 5.x that you get with XenServer

I would have a look at the VM console for the image during the boot process to see what is happening. What you might find is that it is failing to boot (for some reason) then shutting down the instance because of the boot failure. Where did you get that Ubuntu image? Thanks, John From:

Hi, Sorry I missed this, I am still behind on my email. In the current model every XCP node gets a VM with nova-compute running on it, and it must be a linux PV VM. That node does several management tasks. For example, with raw images, it will stream the image into a VDI attached to that VM.
