[Xen-devel] [PATCH RFC 0/3] libxl: upstream Qemu as PV backend for IOEMU stubdom

[Simon Waterman <watermansrdev@xxxxxxxxx>]

This patch adds support for choosing upstream QEMU as the PV QEMU
backend for an IOEMU stubdom instead of qemu-xen-traditional.
The motivation is to expose QEMU features only available in upstream
like VNC auth options.

It adds a new xl.cfg file parameter named device_model_pv_version taking
the same values as device_model_version.  I made the choice configurable
as upstream QEMU requires more RAM than qemu-xen-traditional.

This patch was prompted by guidance from Ian when my SASL patch to
qemu-xen-trad was deemed too complicated.
