PV console for HVM domains Creates a shared memory ring buffer and event channel in HVM domains for passing debug messages from PV drivers on HVM guests The console is used by windows PV drivers to send debug data to xenconsoled Signed-off-by: Owen Smith <owen.smith@citrix.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Isn''t that already solved by the debug io ports in the platform pci code?
