[Xen-devel] [PATCH v2 0/2] Xen (PV and HVM) multiple PV consoles

Hi all,
this small patch series (sent before a few times) achieves two goals:

- make PV consoles work for PV on HVM guests;

- implement support for multiple PV consoles for PV and PV on HVM guests.

Changes in v2:

- nicer safety check in patch #1;

- kzalloc instead of kmalloc;

- removed the spin_lock in vtermno_to_xencons, use

It has been tested with pv and hvm guests, with console=ttyS0,
console=hvc0, and earlyprintk=xen, with and without serial='pty' in the
VM config file.

Stefano Stabellini (2):
      hvc_xen: support PV on HVM consoles
      hvc_xen: implement multiconsole support
