Hi Kei,

I use the Diablo release of openStack and I didn't change anything in
the libvirt XML template.
I can saw a difference for the console file.
The trunk version of Nova use a file for the logging console but the
Diablo Release use a pipe.

Can I change it manually ? Must I open a bur for Diablo release ?

Regards,
Doude.
