[Qemu-devel] [PATCH 0/4] Introduce global config and default devices

[Anthony Liguori <aliguori@us.ibm.com>]

This series introduces global config files stored in /etc/qemu.  There is both
a common config (qemu.conf) and a per-target config (target-<TARGET_NAME>.conf).

To demonstrate what can be done with global config, I've also made some
enhancements to the default device code that allows many of the builtin qemu
defaults to be overridden.  For instance, the following config file would always
disable the monitor on stdio and use virtio-net with tun/tap instead of
slirp.

/etc/qemu/qemu.conf:

[default]
  monitor = "stdio"

[net]
 type = "nic"
 default = "on"
 model = "virtio"

[net]
 type = "tap"
 default = "on"
