Subject: [Xen-devel] [PATCH v4 05/16] libxl: Handle Linux stubdomain specific QEMU options.
Date: Wed, 15 Jan 2020 03:39:44 +0100
Message-ID: <27770209c1e2984cda8b9893ed6313fb2bdf30a6.1579055705.git-series.marmarek@invisiblethingslab.com> (raw)
In-Reply-To: <cover.f819645cd9f5cf7a6f692f9661cfb4e670a2cd08.1579055705.git-series.marmarek@invisiblethingslab.com>

From: Eric Shelton <eshelton@pobox.com>

This patch creates an appropriate command line for the QEMU instance
running in a Linux-based stubdomain.

NOTE: a number of items are not currently implemented for Linux-based
stubdomains, such as:
- save/restore
- QMP socket
- graphics output (e.g., VNC)

Simon:
 * fix disk path
 * fix cdrom path and "format"
 * pass downscript for network interfaces

[drop Qubes-specific parts]

---
Changes in v2:
 - fix serial specified with serial=[ ... ] syntax
 - error out on multiple consoles (incompatible with stubdom)
 - drop erroneous chunk about cdrom
Changes in v3:
 - change to use libxl__stubdomain_is_linux instead of
   b_info->stubdomain_version
 - drop libxl__stubdomain_version_running, prefer
   libxl__stubdomain_is_linux_running introduced by previous patch
 - drop ifup/ifdown script - stubdomain will handle that with qemu
   events itself
 - slightly simplify -serial argument
 - add support for multiple serial consoles, do not ignore
   b_info.u.serial(_list)
 - add error checking for more than 26 emulated disks ("/dev/xvd%c"
   format string)
