Hi Bob,

    Still nothing :(

    I've changed the nova.conf file to reflect the new key:

xenapi_disable_agent=True

    but still doesn't work. I keep getting the timeout error messages in
the nova-compute.log and the dashboard keeps showing the 'Spawning' message
much longer than it should. The instance is up in around 40 seconds, but
the openstack dashboard mark it as running only after around 4 minutes.

    In case it helps, I'm using Debian Wheezy 7.0, Xen 4.1.4 and XCP 1.3.2
as my domU (so it is XCP Kronos), and I obviously have the nova-xcp-plugins
installed.

    BTW, I made a mistake the first time. It is always the other way around
in the nova-compute.log. First I get the 'Running' state change message in
the log, and then all the errors regarding the timout. Sorry about that.

Regards,
Gonzalo.
