一、KVM的编译安装
1、安装基本系统和开发工具
1.1 编译内核
mkdir /root/kvm
cd /root/kvm
wget http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.5.tar.gz
tar -zvxf linux-3.5.tar.gz -C /usr/src
cd /usr/src/linux-2.6.34.4
make menuconfig
vi .config
增加
CONFIG_SYSFS_DEPRECATED_V2=y
CONFIG_STP=m
CONFIG_BRIDGE=m
修改
CONFIG_STP=y
CONFIG_BRIDGE=y
make -j30 all
make modules_install
make install
1.2 安装kvm_mod
wget http://nchc.dl.sourceforge.net/project/kvm/kvm-kmod/3.5/kvm-kmod-3.5.tar.bz2
tar -jvxf kvm-kmod-3.5.tar.bz2
cd kvm-kmod-3.5
./configure
make && make install
reboot
1.3 确认kvm_kmod安装成功
lsmod | grep kvm
kvm_intel 40286 0
kvm 266256 1 kvm_intel
如果你的系统是64位可以直接进行这一步，因为64位的ubuntu是自带kvm模块的
1.4 安装qemu-kvm
apt-get install -y libglib2.0-dev
cd /root/kvm
wget https://launchpad.net/ubuntu/+archive/primary/+files/qemu-kvm_1.0%2Bnoroms.orig.tar.gz
tar -zxf qemu-kvm-0.12.5.tar.gz
cd qemu-kvm-0.12.5
./configure –prefix=/usr/local/kvm –disable-vnc-tls –disable-vnc-sasl –disable-curl –enable-system –static
make && make install
ln -s /usr/local/kvm/bin/qemu-img /usr/bin/qemu-img
ln -s /usr/local/kvm/bin/qemu-io /usr/bin/qemu-io
ln -s /usr/local/kvm/bin/qemu-nbd /usr/bin/qemu-nbd
ln -s /usr/local/kvm/bin/qemu-system-x86_64 /usr/bin/qemu
ln -s /usr/local/kvm/bin/qemu-system-x86_64 /usr/bin/kvm
ln -s /usr/local/kvm/bin/qemu-system-x86_64 /usr/bin/qemu-kvm
二、libvirt的编译安装
apt-get install -y libdevmapper libdevmapper-dev libgnutls-dev libxml2-dev libpciaccess-dev libudev-dev libnl-dev gnutls-bin
cd /root/kvm
wget https://launchpad.net/ubuntu/+archive/primary/+files/libvirt_1.0.2.orig.tar.gz
tar -zxf libvirt_1.0.2.orig.tar.gz
cd libvirt-1.0.2
./configure –prefix=/usr/local/libvirt –enable-debug=no –with-storage-lvm=no
make && make install
ln -s /usr/local/libvirt/bin/virsh /usr/bin/virsh
三、virtinst的编译安装
四、常见错误问题
问题一：configure: error: You must install the GnuTLS library in order to compile and run libvirt
解决方法：
Ubuntu：apt-get install -y libgnutls-dev
问题二：
/usr/local/libvirt/sbin/libvirtd
19:49:56.942: error : virRunWithHook:857 : internal error 'brctl setfd virbr0 0' exited with non-zero status 1 and signal 0: libvir: error : cannot execute binary brctl: No such file or directory
19:49:56.982: warning : qemudStartup:1832 : Unable to create cgroup for driver: No such device or address
解决方法：
Ubuntu：apt-get install -y bridge-utils
问题三：
19:51:11.368: error : virRunWithHook:857 : internal error '/sbin/iptables –table filter –insert FORWARD –destination 192.168.122.0/255.255.255.0 –out-interface virbr0 –match state –state ESTABLISHED,RELATED –jump ACCEPT' exited with non-zero status 1 and signal 0: iptables: Unknown error 18446744073709551615
19:51:11.368: error : networkAddMasqueradingIptablesRules:637 : failed to add iptables rule to allow forwarding to 'virbr0': Invalid argument
19:51:11.420: warning : qemudStartup:1832 : Unable to create cgroup for driver: No such device or address
如果使用桥接网络独立IP可以忽略
问题四：
checking libxml2 xml2-config >= 2.6.0 … configure: error: Could not find libxml2 anywhere (see config.log for details).
解决方法：
Ubuntu: apt-get install -y libxml2-dev
问题五：
configure: error: You must install the GnuTLS library in order to compile and run libvirt
解决方法：
Ubunut： apt-get install -y gnutls-bin(可省)
apt-get install -y libgnutls-dev
问题六：
configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt
解决方法：
Ubunut：apt-get install -y libdevmapper-dev libdevmapper
问题七：
configure: error: libnl-devel >= 1.1 is required for macvtap support
解决方法：
Ubunut：apt-get install -y libnl-dev
问题八：
# ./configure –prefix=/usr –libdir=/usr/lib64 –localstatedir=/var –sysconfdir=/etc –with-hal=yes –with-udev=yes
checking for UDEV… no
configure: error: You must install libudev-devel >= 145 to compile libvirt
解决方法：
Ubunut： apt-get install -y libudev-dev
问题九：
configure: error: You must install libpciaccess-devel >= 0.10.0 to compile libvirt
解决方法：
Ubuntu： apt-get install -y libpciaccess-dev
问题十：
configure: error: You must install python-devel to build Python bindings
解决方法：
Ubuntu：apt-get install -y python-dev
sudo apt-get install python-dev
注：有时依然不能用virsh nodedev-dumpxml pci_0000_00_19_0
#./configure –prefix=/usr –libdir=/usr/lib64 –localstatedir=/var –sysconfdir=/etc –with-hal=yes –with-udev=yes –with-polkit=yes
….
checking for POLKIT… no
configure: error: You must install PolicyKit >= 0.6 to compile libvirt
# apt-get install libpolkit-agent-1-0 libpolkit-backend-1-0 libpolkit-gobject-1-0 libpolkit-gtk-1-0
