第一次用virt-manager建立帶有OS的p_w_picpath時，在最後一步總會遇到下面這個錯誤。後來發現應該是libvirt的問題，選擇從新編譯安裝另外一個版本。這裏從新選擇的時libvirt-1.1.4node

Unable to complete install: 'Failed to connect socket to '/var/run/libvirt/virtlogd-sock': No such file or directory'python

libvirtError: Failed to connect socket to '/var/run/libvirt/virtlogd-sock': No such file or directorymysql

在用virt-manager建立帶有OS的p_w_picpath時，許kvm和libvirt安裝且正常運行，有以下輸出即可：sql

root@u-node4:/home/zxl# kvm-okubuntu

INFO: /dev/kvm existsvim

KVM acceleration can be usedapi

root@u-node4:/tool/libvirt-1.3.4# virsh list服務器

Id Name Stateapp

----------------------------------------------------dom

而後安裝qemu 和virt-manager

root@u-node4:/tool/libvirt-1.3.4# apt-get install qemu virt-manager

root@u-node4:~# virt-manager （若是出現DBUS問題，那麼在切換用戶時注意用su - 代替su)

報錯，找不到br100網卡

而且本實驗要建立的p_w_picpath中的虛擬機是要將虛擬網卡創建在網橋上的，即建立基於虛擬局域網的虛擬網卡。此虛擬局域網能夠讓位於同一臺物理服務器上的虛擬機再次組成一個局域網

點擊finish安裝虛擬機

當裝完操做系統，且安裝了虛擬機中須要使用的軟件後，就能夠將虛擬機關閉

在宿主機執行virsh destroy ubuntu-12.04即可關閉虛擬機

root@u-node4:~# virsh destroy ubuntu-12.04

Domain ubuntu-12.04 destroyed

root@u-node4:~# virsh list --all

Id Name State

----------------------------------------------------

- ubuntu-12.04 shut off

接下來須要保存虛擬機的定義文件和虛擬機p_w_picpath

保存好虛擬機的定義文件後，找到第文件中關於虛擬機的硬盤p_w_picpath定義部分

</disk>

source file指明瞭虛擬磁盤p_w_picpath的全路徑，將此p_w_picpath剪切至保存目錄，如p_w_picpath目錄，則保存虛擬機p_w_picpath完畢

root@u-node6:~# mv /var/lib/libvirt/p_w_picpaths/ubuntu-12.04.img /p_w_picpath/

root@u-node6:~# mv ubuntu-12.04.xml /p_w_picpath/

因爲此虛擬機不在使用，則能夠udefine此虛擬機（udefine不是刪除，只是取消了此虛擬機的定義）

root@u-node4:~# virsh undefine ubuntu-12.04

Domain ubuntu-12.04 has been undefined

root@u-node4:~# virsh list --all

總結：

裝kvm,libvirt，virt-manager失敗許屢次的解決方法：

1：配置搜狐源

2：apt-get install qemu-kvm ubuntu-vm-builder bridge-utils

3: apt-get install qemu virt-manager(此時其實會裝libvirt-bin，有依賴,但可能運行virt-manager報錯，需最後purge掉）

4: apt-get install build-essential python-dev libxml2-dev libxslt-dev tgt lvm2 python-lxml unzip python-mysqldb mysql-client memcached openssl expect iputils-arping python-xattr python-lxml kvm gawk iptables ebtables sqlite3 sudo kvm vlan curl socat python-libxml2 iscsitarget iscsitarget-dkms open-iscsi build-essential libxml2 libxml2-dev make fakeroot dkms openvswitch-switch openvswitch-datapath-dkms libxslt1.1 libxslt1-dev vlan gnutls-bin libgnutls-dev cdbs debhelper libncurses5-dev libreadline-dev libavahi-client-dev libparted0-dev libdevmapper-dev libudev-dev libpciaccess-dev libcap-ng-dev libnl-3-dev libapparmor-dev python-all-dev libxen-dev policykit-1 libyajl-dev libpcap0.8-dev libnuma-dev radvd libxml2-utils libnl-route-3-200 libnl-route-3-dev libnuma1 numactl libnuma-dbg libnuma-dev dh-buildinfo expect ebtables iptables iputils-ping iputils-arping sudo dnsmasq-base dnsmasq-utils

5: tar -xf libvirt-1.1.4.tar.gz

6:/configure --prefix=/usr --sysconfdir=/etc

7:make && make install

8:virt-manage 安裝虛擬機

此時若是報APP的錯誤，則執行apt-get purge libvirt-bin,而後進入到執行./configure的目錄執行make clean，在從新執行6和7步，即可.
