[openstack-dev] Unable to logging to guest console on XCP/xenserver
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.

Re: [openstack-dev] Unable to logging to guest console on XCP/xenserver
The trace below seems to be wanting to access the console log, rather than the
VNC console.
I believe there is a blog post about how to enable this, but basically you need
a cronjob to run in dom0 to rotate the logs. This is because the Xen console
logging is not ring-based, and therefore without a cronjob it will fill the
logging up. Therefore it is not enabled by default.
To enable the console log, check out
https://github.com/openstack/nova/blob/master/tools/xenserver/rotate_xen_guest_logs.sh
and add crontab entries for that script as described at the top of the file.
The first invocation of the script will enable the console logs for your VMs
and you then won't see the error log.
Thanks,
Bob
