qemu 下載與安裝
1. 下載:
Qemu 下載網頁 - http://wiki.qemu.org/Download
2. 解壓縮:
tar xfva qemu-2.5.0.tar.bz2
解開後會出現 qemu-2.5.0 目錄
3. 設定前安裝套件:
libtool
zlib1g-dev
pkg-config
libsdl1.2-dev
libcurl4-openssl-dev
libsasl2-dev
libaio-dev
libvde-dev
libvdeplug2-dev
uuid-dev
libcap-ng-dev
4. 設定:
在 qemu-2.5.0 目錄下執行:
./configure
請注意底下兩個參數一定要設定成功:
SDL support yes
KVM support yes
如果有類似底下訊息時:
lzo support no
bzip2 support no
我們可以編輯 configure 這個檔案,搜尋 bzip2 與 lzo 這兩個關鍵字,此時會發現有底下片段,分別是:
if test "$bzip2" = "yes"; then
feature_not_found "libbzip2" "Install libbzip2 devel"
fi
以及
if test "$lzo" = "yes"; then
feature_not_found "liblzo2" "Install liblzo2 devel"
fi
這表示我們的系統中沒有安裝 bzip2 devel 以及 lzo devel 套件,在 Debian 底下,此兩個套件的名稱為:
libbz2-dev
liblzo2-dev
將上述兩個套件安裝,再執行 ./configure 後會發現 lzo 及 bzip2 都已支援,其訊息如下:
lzo support yes
bzip2 support yes
其它找不到套件的訊息依此類推來解決,理論上可以作到的訊息如下:
./configure

5. 編譯 qemu
請在設定完成後執行:
make -j 8 (8 核)
6. 安裝
請以 root 權限執行底下指令:
make install
將 qemu 安裝在 /usr/local/bin 目錄下
7. 測試
X86 版本:
請執行底下指令:
$ qemu-system-x86_64 -version
qemu-system-x86_64: error while loading shared libraries: libiscsi.so.1: cannot open shared object file: No such file or directory
我們會看到 qemu-system-x86_64 抱怨找不到 libiscsi.so.1,這最主要的原因目前的 libiscsi 這個動態連結函式庫的檔名已經是 libiscsi.so.2 了,所以 qemu 找不到 libiscsi.so.1,要解決此問題,我們要手動新增這個檔案,請以 root 權限切換至 /usr/lib/x86_64-linux-gnu 目錄,執行:
/usr/lib/x86_64-linux-gnu# ls -l libiscsi.so*
lrwxrwxrwx 1 root root 18 Jul 31 2014 libiscsi.so -> libiscsi.so.2.1.12
lrwxrwxrwx 1 root root 18 Jul 31 2014 libiscsi.so.2 -> libiscsi.so.2.1.12
-rw-r--r-- 1 root root 143344 Jul 31 2014 libiscsi.so.2.1.12
可以看到目前只有 libiscsi.so.2 這個檔案,在此目錄中要再新增 libiscsi.so.1 連結檔,指令如下:
/usr/lib/x86_64-linux-gnu# ln -s libiscsi.so.2.1.12 libiscsi.so.1
之後可以再執行 ls 確認一下連結檔是否已建立成功:
/usr/lib/x86_64-linux-gnu# ls -l libiscsi*
-rw-r--r-- 1 root root 223084 Jul 31 2014 libiscsi.a
lrwxrwxrwx 1 root root 18 Jul 31 2014 libiscsi.so -> libiscsi.so.2.1.12
lrwxrwxrwx 1 root root 18 Mar 25 10:43 libiscsi.so.1 -> libiscsi.so.2.1.12
lrwxrwxrwx 1 root root 18 Jul 31 2014 libiscsi.so.2 -> libiscsi.so.2.1.12
-rw-r--r-- 1 root root 143344 Jul 31 2014 libiscsi.so.2.1.12
此時再執行 qemu 即沒有問題:
$ qemu-system-x86_64 -version
QEMU emulator version 2.5.0, Copyright (c) 2003-2008 Fabrice Bellard
qemu-system-arm -M ?
可以看到 qemu arm 模擬器的資訊
qemu-system-arm -version
可以看到 qemu 模擬器版本資訊
