1 基于centos8 qemu src rpm

1.1 环境准备

下载src rpm

https://vault.centos.org/8.2.2004/AppStream/Source/SPackages/qemu-kvm-2.12.0-99.module_el8.2.0+524+f765f7e0.4.src.rpm

安装额外的repo

  • epel

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

或者

yum install epel-release -y

  • enable powertools

编辑/etc/yum.repos.d/CentOS-PowerTools.repo，设置enabled=1

准备rpmbuild开发环境

https://blog.csdn.net/get_set/article/details/53453320

  • yum install -y rpm-build rpmdevtools
  • cd /root && rpmdev-setuptree

rpmdev-setuptree这个命令就是安装rpmdevtools带来的。可以看到运行了这个命令之后，在$HOME目录下多了一个叫做rpmbuild的文件夹，里边内容如下：

  1. $ tree rpmbuild
  2. rpmbuild
  3. ├── BUILD
  4. ├── RPMS
  5. ├── SOURCES
  6. ├── SPECS
  7. └── SRPMS

安装src rpm

rpm -ivh qemu-kvm-2.12.0-99.module_el8.2.0+524+f765f7e0.4.src.rpm

src rpm会安装到$HOME/rpmbuild/下

安装rpmbuild qemu-kvm.spec的依赖

在$HOME/rpmbuild/SPECS/下执行rpmbuild -bp qemu-kvm.spec时会报缺少以下依赖

  1. [root@localhost SPECS]# rpmbuild -bp qemu-kvm.spec

其中，比较特殊的依赖有

  • iasl

yum search iasl是找不到相关包，但是可以直接yum install -y iasl，因为iasl是在acpica-tools中的

  • python3-devel

yum search python3-devel,是找不到相关包，但是可以直接yum install -y python3-devel

然后建立软连接

ln -sf /usr/bin/python3 /usr/bin/python

  • pkgconfig(epoxy)

yum install -y libepoxy-devel.x86_64

  • pkgconfig(gbm)

yum install -y mesa-libgbm-devel.x86_64

  • pkgconfig(libdrm)

yum install -y libdrm-devel.x86_64

  • pkgconfig(xkbcommon)

yum install -y libxkbcommon-devel.x86_64

其他的包，可以直接使用以下命令安装

  1. yum install -y bluez-libs-devel brlapi-devel check-devel cyrus-sasl-devel device-mapper-multipath-devel glib2-devel glusterfs-api-devel glusterfs-devel gnutls-devel libaio-devel libattr-devel libcacard-devel libcap-devel libcap-ng-devel libcurl-devel libgcrypt-devel libiscsi-devel libpmem-devel libpng-devel librados-devel librbd-devel libseccomp-devel libssh-devel libusbx-devel libuuid-devel lzo-devel ncurses-devel nss-devel numactl-devel pciutils-devel pixman-devel rdma-core-devel snappy-devel spice-protocol spice-server-devel systemd-devel systemtap-sdt-devel texinfo usbredir-devel zlib-devel

2 直接build qemu code

  • 编译命令
  1. ./configure --enable-kvm --prefix=/home/zhanghaoyu/qemu-obj/ --enable-debug --target-list=x86_64-softmmu
  2. make && make install
  • 依赖包安装
    • python
