Re: [Xen-devel] Qemu vnc color depth

This should be the default behaviour

This is evil. If we need a way to notify the client of colour depth
changes, then we should define an official VNC extension for this that clients can implement. cf the desktop-resize extension

So, if the client supports the extension use that to notify, otherwise
fallback to doing server-side conversions.

This is a good idea, I just hope it won't take ages to be accepted.
I'll work on this.

By default I am doing 1), however the second choice can be enabled passing the -vnc-switch-bpp command line option.

Don't add more command line options - the existing -vnc flag already
has the ability to take multiple flags in the format:

    -vnc hostname:display,flag,flag,flag,flag


    -vnc localhost:1,passwd,tls

another good suggestion, I'll modify the patch to use this.

Please send this to qemu-devel - we should not be introducing yet more
xen-specific forks to the QEMU code we have - it is a maintainance
disaster already with the number of patches we have.

Yeah I know, but sending patches to qemu-devel is like &>/dev/null
