?1.KVM主機虛擬機直接克隆

virt-clone?-o?module-IT?-n?lb-test2?-f?/data/vm/vmfiles/lb-tes2.img 說明：以modeule-IT做為源，克隆module-IT以及module-IT.img，并創(chuàng)建名稱為lb-test2，鏡像為-f?/data/vm/vmfiles/lb-tes2.img

啟動虛擬機配置主機名，IP地址等

2.通過復(fù)制配置文件與磁盤文件的虛擬機克隆（適用于異機的靜態(tài)遷移）

（1）確認(rèn)源虛擬機：

[root@server?~]#?virsh?list?--allId????Name???????????????????????????State ----------------------------------------------------1?????test1??????????????????????????running2?????lu-test1???????????????????????running3?????module-IT-oa-test??????????????running4?????test2-IT???????????????????????running5?????IT-clone-TEST??????????????????running9?????LB_test1???????????????????????running10????lb-test2???????????????????????running-?????clean??????????????????????????shut?off-?????module-IT??????????????????????shut?off-?????Winprinter?????????????????????shut?off [root@server?~]#?virsh?shutdown?LB_test1 Domain?lb-test2?is?being?shutdown

（2）.導(dǎo)入KVM虛擬機配置文件

[root@server?~]#?virsh?dumpxml?LB_test1?>/etc/libvirt/qemu/LB_test2.xml

（3）.復(fù)制KVM虛擬機磁盤文件

[root@server?vmfiles]#?cp?binzai.qcow2?binzai-test2.qcow2

（4）.直接編輯配置文件

[root@server?vmfiles]#?vim?/etc/libvirt/qemu/LB_test2.xml? <domain?type='kvm'><name>LB_test1</name>??#由字母和數(shù)字組成，不能包含空格<uuid>9ea6f52f-1a18-5a8a-7920-611efa92c8c9</uuid>??#由命令行工具uuidgen生成<memory?unit='KiB'>1048576</memory>???#在不reboot?guest情況下，guset可以使用的最大內(nèi)存，以KB為單位<currentMemory?unit='KiB'>1048576</currentMemory>??#guest啟動時內(nèi)存，可以通過virsh?setmem來調(diào)整，但是不能大于最大可使用內(nèi)存<vcpu?placement='static'>1</vcpu>??#分配的虛擬CPU<os><type?arch='x86_64'?machine='rhel6.4.0'>hvm</type>??#架構(gòu)：64位，machine：宿主機的操作系統(tǒng)<boot?dev='hd'/>??#指定啟動設(shè)備，可以重復(fù)多行，指定不同的值，作為一個啟動設(shè)備列表</os><features>???#處理器特性<acpi/><apic/><pae/></features><clock?offset='utc'/>??#（utc該為localtime）Kvm虛擬機采用utc時間，需要先修改配置文件使用KVM虛擬機的時間與虛擬主機同步。<on_poweroff>destroy</on_poweroff>?#停止虛擬機，相當(dāng)于關(guān)閉電源，Kill?kvm進(jìn)程也是一樣<on_reboot>restart</on_reboot>??<on_crash>restart</on_crash><devices><emulator>/usr/libexec/qemu-kvm</emulator>??#模擬元素<disk?type='file'?device='disk'><driver?name='qemu'?type='qcow2'?cache='none'/><source?file='/var/lib/libvirt/p_w_picpaths/binzai.qcow2'/>???#使用qumu-img命令創(chuàng)建該文件，kvm?p_w_picpath的默認(rèn)目錄為：。。。。。<target?dev='vda'?bus='virtio'/><address?type='pci'?domain='0x0000'?bus='0x00'?slot='0x05'?function='0x0'/></disk>???? #采用普通的驅(qū)動，即硬盤和網(wǎng)卡都采用默認(rèn)配置情況下，硬盤為ide模式，采用virtio驅(qū)動，硬盤工作在SCSI模式下<controller?type='usb'?index='0'><address?type='pci'?domain='0x0000'?bus='0x00'?slot='0x01'?function='0x2'/></controller><interface?type='bridge'>??#網(wǎng)卡<mac?address='52:54:00:93:45:fe'/><source?bridge='br0'/><model?type='virtio'/><address?type='pci'?domain='0x0000'?bus='0x00'?slot='0x03'?function='0x0'/></interface><serial?type='pty'><target?port='0'/></serial><console?type='pty'><target?type='serial'?port='0'/></console><input?type='tablet'?bus='usb'/><input?type='mouse'?bus='ps2'/><graphics?type='vnc'?port='-1'?autoport='yes'/><sound?model='ich6'><address?type='pci'?domain='0x0000'?bus='0x00'?slot='0x04'?function='0x0'/></sound><video><model?type='cirrus'?vram='9216'?heads='1'/><address?type='pci'?domain='0x0000'?bus='0x00'?slot='0x02'?function='0x0'/></video><memballoon?model='virtio'><address?type='pci'?domain='0x0000'?bus='0x00'?slot='0x06'?function='0x0'/></memballoon></devices> </domain>

（5）.定義新虛擬機配置文件

[root@server?vmfiles]#?virsh?define?/etc/libvirt/qemu/LB_test2.xml

（6）.啟動虛擬

virsh?start?LB_test2
