一、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
