[Qemu-devel] [PATCH 0/3] Add options to make writing a front end easier

[Anthony Liguori <aliguori@cs.utexas.edu>]

Howdy,

I've been working on a QEMU front end for a bit now.  The following 
patch introduces a number of things to make writing front ends in 
general a bit easier.  This includes making the char devices exposable 
as unix sockets and adding a daemonize option.

Unix sockets are useful for a front end because their permissions can be 
controlled and it's easier to guarantee uniqueness (verses trying to 
find an unused TCP port).

The daemonize option is useful as it provides a deterministic way to 
know that QEMU is ready to accept connections (for something like VNC).  
Otherwise, you have to use a connect loop and timeout attempting to 
connect.  This gets particularly ugly when an error occurs for some reason.

I've made an attempt to support the Win32 build but I haven't verified 
that current CVS is buildable (my changes shouldn't make it any worse).

Regards,

Anthony Liguori
