Folks,
Does anyone know whether libvirt provides a means for me to guarantee a
persistent link for my guest's virtual serial console? I need to have a
consistent mapping (for example, a symlink that always points to the
correct /dev/pts entry) so I can automate kgdb hookup on boot.
Jon.

The /dev/pts path for a guest is always recorded in the XML, so just query
the XML file for it once it is running to discover the allocated path, or
use the convenient 'virsh ttyconsole' command which prints just the path
immediately.

Ooh, now that's useful. It would also be nice to have a symlink, but I
think this will do for the moment - thanks!
Jon.
P.S. Thanks for awesome blog post on NUMA.
