Re: [Openstack] Get nova diagnostics to work with libvirt

2012-03-16 Thread Leander Bessa 
I don't remember where exactly i copied this from, but i found this in the
mailing list somewhere. This supposedly is the output produced by the
nova-diagnostics command with xen. Maybe this can help?

Re: [Openstack] Get nova diagnostics to work with libvirt

2012-03-12 Thread Vishvananda Ishaya 
I gave pretty detailed instructions the last time this came up:

http://www.mail-archive.com/openstack@lists.launchpad.net/msg06980.html

That should be enough to get you started.

Diagnostics are a bunch of key/value pairs, but unfortunately there doesn't 
seem to be an example of what they are.  If someone running xen could post the 
result of get_diagnostics so that it could be added to a docstring and 
implemented for libvirt, that would be awesome.

 Hello,
 
 If recall correctly, the nova diagnostics command does not work with libvirt. 
 I can't find the exact post where this happend, but someone suggested that i 
 could implement the diagnostics command for libvirt. If so, where in the 
 openstack source code should i look to find the required interface/class for 
 this command? I'm using Ubuntu 11.10 and OpenStack Diablo.
 
 Regards,
 
 Leander
