Open Stack

Hi,

I am trying to use Openstack Havana to control XCP hypervisor with neutron
OVS plugin. I can launch instances normally but unable to logging to guest
console. Please see the below log from nova compute to get a clear idea.

Log:

Any pointers to debug the issue would be really helpful. Please let me know
how I can debug this issue.
