Raspberry Piの QEMUエミュレータで Windows互換の ReactOSを動かす方法 Raspberry Piの QEMUエミュレータで Windows互換の ReactOSを動かす方法

● Raspberry Piの QEMUエミュレータで Windows互換 OSの ReactOSを動かす

 ラズパイの QEMUエミュレータで ReactOSを動かせる事を知り、動かしてみました。
 (動くだけで実用性は全く有りません。そこに ラズパイと QEMUと ReactOSが有るからみたいな。)

 ReactOSとは Windows NT互換を目標にしているオープンソースのフリー OSです。(現在アルファ版で ReactOS自身の実用度も殆ど有りません)
ReactOS is a Free operating system.
 ReactOS is a Opensource operating system.

 Windows 2000をいじくっている時は ReactOSに大きな関心と期待を寄せていましたが、2018年現在では時既に遅しで価値を見出せなくなりました。(開発陣が未だにモチベーションを保って開発を継続している事には驚きを禁じ得ません)

 Raspbian OSは Raspbian Stretch(2018/04/18版)を使用しました。
pi@raspberrypi:~ $ uname -a
Linux raspberrypi 4.14.34-v7+ #1110 SMP Mon Apr 16 15:18:51 BST 2018 armv7l GNU/Linux

 ラズパイ本体は Pi 3B+を使用しました。

●ラズパイで QEMUエミュレータをビルドする

 最初はお決まりの手順(apt-get update)で、次に QEMUのビルドに必要なライブラリをインストールします。
sudo apt-get update
sudo apt-get -y install git
sudo apt-get -y install zlib1g-dev
sudo apt-get -y install libsdl2-dev
sudo apt-get -y install libpixman-1-dev

 QEMUを Gitから cloneしてソースリストを取得します。
cd
# git clone https://github.com/qemu/qemu.git
git clone git://git.qemu.org/qemu.git --branch v2.12.0 --single-branch --depth 1
# Note: checking out '4743c23509a51bd4ee85cc272287a41917d1be35'.
cd qemu

mkdir build
cd build

../configure --target-list="i386-softmmu" --enable-sdl

make

sudo make install



● ラズパイ用 QEMUエミュレータで ReactOSを動かす方法(VMware)

ReactOS An operating system based on the best Windows NT design principles

 VMware形式のイメージで ReactOSの起動を確認。(ただし実用性は有りません)
 ※ ReactOSの VMware形式の提供は 0.4.5 2017-05-17が最後。
# ReactOS 0.3.17 VMware 2015-04-07 OK
wget https://excellmedia.dl.sourceforge.net/project/reactos/ReactOS/0.3.17/ReactOS-0.3.17-REL-VMware.zip

wget https://excellmedia.dl.sourceforge.net/project/reactos/ReactOS/0.4.5/ReactOS-0.4.5-REL-VMware.zip
unzip ReactOS-0.4.5-REL-VMware.zip
qemu-system-i386 ReactOS.vmdk -m 64
※-mのメモリの指定で 96を指定すると再起動ループで起動しない。
※-mのメモリの指定で 128とかを指定すると青画面で起動しない。

                Linux kernel 3.3+ as well as most routers can talk
                L2TPv3. This transport allows connecting a VM to a VM,
                VM to a router and even VM to Host. It is a nearly-universal
                standard (RFC3391). Note - this implementation uses static
                pre-configured tunnels (same as the Linux kernel).

                on|off controls leading timestamps (default:on)
-dump-vmstate <file>
                Output vmstate information in JSON format to file.
                Use the scripts/vmstate-static-checker.py file to
                check for possible regressions in migration code
                by comparing two such vmstate dumps.

Generic object creation:
-object TYPENAME[,PROP1=VALUE1,...]
                create a new object of type TYPENAME setting properties
                in the order they are specified.  Note that the 'id'
                property must be set.  These objects are placed in the
                '/objects' path.

During emulation, the following keys are useful:
ctrl-alt-f      toggle full screen
ctrl-alt-n      switch to virtual console 'n'
ctrl-alt        toggle mouse and keyboard grab

When using -nographic, press 'ctrl-a h' to get some help.
