[Qemu-devel] [patch 0/7] qemu-kvm compat (v2)

[Marcelo Tosatti]

As discussed on this weeks qemu call, follows qemu-kvm compat patches
for qemu:

    - command line compatibility
    - allow configurable ram size for cirrus

Jan, please ACK.

v2:

- add -no-kvm command line compatibility
- change command documentation to deprecated style
- improve changelogs

[Qemu-devel] [patch 1/7] cirrus_vga: allow configurable vram size

[Marcelo Tosatti]

[-- Attachment #1: 01_cirrus-add-configurable-memsize --]
[-- Type: text/plain, Size: 3015 bytes --]

Allow RAM size to be configurable for cirrus, to allow migration 
compatibility from qemu-kvm.

This doesn't emulate anything. It just adds a warning that some long
disabled option was used.

It emulates the command line switch. In my mind, "printing a warning"
can be considered "emulating a command from qemu-kvm". If you prefer 
something else, please let me know the best wording.

"Use machine options to emulate..." makes no sense for those
warning-only switches. It makes sense where we translate them and
register the corresponding machine options.

So call this "Issue warning when deprecated -bla is used" or so.

To avoid breaking scenarios which are setup with command line

Port drive boot option. From the qemu-kvm original commit message:

We do not want to maintain this option forever. It will be removed after
a grace period of a few releases. So warn the user that this option has
no effect and will become invalid soon.

[Qemu-devel] [patch 6/7] Emulate qemu-kvms -tdf option

[Marcelo Tosatti]

[-- Attachment #1: 06_qemukvm-commandline-opt-tdf --]
[-- Type: text/plain, Size: 1530 bytes --]

From: Jan Kiszka <jan.kiszka@siemens.com>

Releases of qemu-kvm will be interrupted at qemu 1.3.0.
Users should switch to plain qemu releases.
To avoid breaking scenarios which are setup with command line
options specific to qemu-kvm, port these switches from qemu-kvm
to qemu.git.

Port -tdf option.
