1、准备的镜像以及RPM包 （1）需要准备的ISO CentOS-6.0-x86_64-bin-DVD1.iso CentOS-6.0-x86_64-bin-DVD2.iso （2）需要额外到CentOS 6.4或CentOS 6.3下载的如下安装包： libjpeg-turbo-1.2.1-1.el6.x86_64.rpm libjpeg-turbo-devel-1.2.1-1.el6.x86_64.rpm libusb1-1.0.9-1.1.x86_64.rpm libusb1-devel-1.0.9-1.1.x86_64.rpm pixman-0.18.4-1.el6_0.1.x86_64.rpm pixman-devel-0.18.4-1.el6_0.1.x86_64.rpm spice-protocol-0.12.2-1.el6.noarch.rpm spice-server-0.12.0-12.el6.x86_64.rpm spice-server-devel-0.12.0-12.el6.x86_64.rpm （3）下载qemu-1.2.0-23.fc18.src.rpm相关的SRPM包 需要到http://mirrors.ustc.edu.cn/fedora/linux/releases/18/Fedora/source/SRPMS/目录下载如下SRPM包 usbredir-0.5.2-1.fc18.src.rpm libseccomp-1.0.1-0.fc18.src.rpm qemu-1.2.0-23.fc18.src.rpm 如果rpm-build-4.8已经升级到rpm-build-4.9,那么systemtap也必须升级，需要额外下载如下包 systemtap-2.0-4.fc18.src.rpm 编译后安装如下包 rpm -ivh systemtap-2.0-4.el6.x86_64.rpm systemtap-client-2.0-4.el6.x86_64.rpm systemtap-devel-2.0-4.el6.x86_64.rpm systemtap-sdt-devel-2.0-4.el6.x86_64.rpm systemtap-runtime-2.0-4.el6.x86_64.rpm 2、制作本地YUM安装源 vi /etc/yum.repos.d/iso.repo 添加如下内容： [CentOS6.0] name = CentOS6.0 baseurl = file:///iso file:///iso2 enabled = 1 gpgcheck = 0 挂载ISO镜像 mount -o loop CentOS-6.0-x86_64-bin-DVD1.iso /iso mount -o loop CentOS-6.0-x86_64-bin-DVD2.iso /iso2 3、使用rpmbuild重新编译qemu-1.2.0-23.fc18.src.rpm rpmbuild --rebuild qemu-1.2.0-23.fc18.src.rpm 注意：这个过程中会提示缺少很多依赖的安装包，解决办法： （1）用yum install从本地源中安装，注意提示的版本号得符合要求 （2）用rpm -ivh（或是升级安装rpm -Uvh）来安装额外从CentOS 6.4或CentOS 6.3中下载的RPM包 （3）用rpmbuild --rebuild来编译如下两个包 usbredir-0.5.2-1.fc18.src.rpm libseccomp-1.0.1-0.fc18.src.rpm 编译完成后生成的包如下： /root/rpmbuild/RPMS/x86_64/usbredir-server-0.5.2-1.el6.x86_64.rpm /root/rpmbuild/RPMS/x86_64/usbredir-devel-0.5.2-1.el6.x86_64.rpm /root/rpmbuild/RPMS/x86_64/usbredir-debuginfo-0.5.2-1.el6.x86_64.rpm /root/rpmbuild/RPMS/x86_64/usbredir-0.5.2-1.el6.x86_64.rpm /root/rpmbuild/RPMS/x86_64/libseccomp-1.0.1-0.el6.x86_64.rpm /root/rpmbuild/RPMS/x86_64/libseccomp-devel-1.0.1-0.el6.x86_64.rpm /root/rpmbuild/RPMS/x86_64/libseccomp-debuginfo-1.0.1-0.el6.x86_64.rpm 根据需要用rpm -ivh(或rpm -Uvh)安装这些二进制包。 出现一些问题的处理： （1）安装libseccomp-1.0.1-0.el6.x86_64.rpm出错 rpm -ivh libseccomp-1.0.1-0.el6.x86_64.rpm error: Failed dependencies: kernel >= 3.5 is needed by libseccomp-1.0.1-0.el6.x86_64 原因：因为CentOS 6.0内核版本为2.6.32-71.el6.x86_64,不符合其依赖的内核版本>= 3.5，测试过忽略这个依赖对编译qemu-kvm没有影响,编译出来的qemu-kvm可以在CentOS 6.0下正常运行。 解决方法： rpm -ivh libseccomp-1.0.1-0.el6.x86_64.rpm --nodeps （2）File not found: /root/rpmbuild/BUILDROOT/qemu-1.2.0-23.fc18.x86_64/usr/bin/vscclient 原因：因为CentOS 6.0内核版本为2.6.32-71.el6.x86_64,这个涉及到smartcard nss 的支持，对于内核版本小于3.12.8的则不支持，所以就不编译vscclient，到最后打qemu-img这个包就找不到该文件。对于CentOS 6.0而言这个不是必须的，所以可以删除。 /root/rpmbuild/SPECS/qemu.spec里部分关于smartcard nss 的说明： " --disable-smartcard-nss disable smartcard nss support" " --enable-smartcard-nss enable smartcard nss support" 解决方法： vi /root/rpmbuild/SPECS/qemu.spec 删除如下红色行： %files img �fattr(-,root,root) %{_bindir}/qemu-img %{_bindir}/qemu-io %{_bindir}/vscclient %{_mandir}/man1/qemu-img.1* 然后执行：rpmbuild -ba /root/rpmbuild/SPECS/qemu.spec （3）File must begin with "/": %{_unitdir}/qemu-guest-agent.service 原因: %{_unitdir}这个宏定义在Fedora release 18的rpmbuild 的宏定义配置文件中才有，对于CentOS 6.0而言是不存在的，再加上qemu-guest-agent.service 这个服务启动配置文件是针对Fedora release 18，对CentOS 6.0没有意义，所以可以删除掉。 解决方法： vi /root/rpmbuild/SPECS/qemu.spec 删除如下红色行： %files guest-agent �fattr(-,root,root,-) %doc COPYING README %{_bindir}/qemu-ga %{_unitdir}/qemu-guest-agent.service %{_udevdir}/99-qemu-guest-agent.rules 然后执行：rpmbuild -ba /root/rpmbuild/SPECS/qemu.spec （4）安装qemu-kvm-1.2.0-23.el6.x86_64.rpm报错 rpm -ivh qemu-kvm-1.2.0-23.el6.x86_64.rpm error: Failed dependencies: ipxe-roms-qemu is needed by qemu-kvm-2:1.2.0-23.el6.x86_64 qemu-common = 2:1.2.0-23.el6 is needed by qemu-kvm-2:1.2.0-23.el6.x86_64 seabios-bin >= 0.6.0-2 is needed by qemu-kvm-2:1.2.0-23.el6.x86_64 sgabios-bin is needed by qemu-kvm-2:1.2.0-23.el6.x86_64 vgabios >= 0.6c-2 is needed by qemu-kvm-2:1.2.0-23.el6.x86_64 原因：缺少这些依赖包 解决办法：与步骤3一样，将这些依赖的包安装上即可。 需要额外下载的RPM包： ipxe-roms-qemu-20120328-1.1.noarch.rpm #可以直接安装 sgabios-bin-0-0.3.20110621svn.el6.noarch.rpm #可以直接安装 vgabios-0.6c-2.fc14.noarch.rpm #可以直接安装 seabios-0.6.2-3.fc16.src.rpm # 编译成 seabios-bin-0.6.2-3.el6.noarch.rpm 后再安装 seabios-0.6.2-3.fc16.src.rpm 的下载地址： http://mirrors.ustc.edu.cn/fedora/linux/releases/16/Everything/source/SRPMS/ （5）安装qemu-common-1.2.0-23.el6.x86_64.rpm 报错 rpm -ivh qemu-common-1.2.0-23.el6.x86_64.rpm error: Failed dependencies: systemd-units is needed by qemu-common-2:1.2.0-23.el6.x86_64 原因：systemd-units 只有Fedora release 18才有这个服务，对于CentOS 6.0不需要，可以去除该依赖关系 解决办法<1>： rpm -ivh qemu-common-1.2.0-23.el6.x86_64.rpm --nodeps 解决办法<2>: vi /root/rpmbuild/SPECS/qemu.spec 将红色行删除 %package common Summary: QEMU common files needed by all QEMU targets Group: Development/Tools Requires(post): /usr/bin/getent Requires(post): /usr/sbin/groupadd Requires(post): /usr/sbin/useradd Requires(post): systemd-units Requires(preun): systemd-units Requires(postun): systemd-units 按照CentOS 6.0的qemu-kvm-0.12.1.2-2.113.el6.x86_64.rpm的SPEC修改如下红色行： %post common if [ $1 -eq 1 ] ; then #
