qemu-kvm安裝kvm

1.BIOS開啟虛擬化

2.啟用kvm模塊

#modprobe?kvm

關(guān)閉防火墻

#?systemctl?stop?firewalld.service

3.功能區(qū)分intel/amd的啟用

#modprobe?kvm-intel #?lsmod?|?grep?kvm kvm_intel?????????????170181??3? kvm???????????????????554609??1?kvm_intel irqbypass??????????????13503??1?kvm

4.安裝kvm

#yum?install?-y?qemu-kvm?libvirt?virt-manager?qemu-kvm-tools

5.安裝網(wǎng)橋管理工具tunctl

下載：http://www.rpmfind.net/linux/rpm2html/search.php?query=tunctl

#?yum?install?tunctl-1.5-3.el6.x86_64.rpm

6.掛載U盤，拷貝鏡像文件

首先要進(jìn)入官網(wǎng)下載NTFS-3G工具

http://www.tuxera.com/community/ntfs-3g-download/

6.1.下載之后進(jìn)行解壓

wget?http://tuxera.com/opensource/ntfs-3g_ntfsprogs-2014.2.15.tgz tar?-xvf?ntfs-3g_ntfsprogs-2014.2.15.tgz

6.2.編譯并進(jìn)行安裝

cd?ntfs-3g_ntfsprogs-2014.2.15 ./configure make make?install

6.3.掛載NTFS

mount?-t?ntfs-3g?/dev/sda2??/mnt/ckl

6.5.拷貝

cp?/mnt/ckl/CentOS-7-x86_64-DVD-1611.iso?/root/CentOS-7-x86_64-DVD-1611.iso

7.配置網(wǎng)卡

7.1.會(huì)自動(dòng)啟動(dòng)一個(gè)橋設(shè)備，這相當(dāng)于VMware Workstation中的host-only僅主機(jī)的網(wǎng)絡(luò)設(shè)備；

#?ifconfig? ens3:?flags=4163<UP,BROADCAST,RUNNING,MULTICAST>??mtu?1500inet?192.168.1.3??netmask?255.255.255.0??broadcast?192.168.1.255inet6?fe80::ec4:17fa:8756:5a8f??prefixlen?64??scopeid?0x20<link>ether?00:1d:72:58:6f:93??txqueuelen?1000??(Ethernet)RX?packets?2606??bytes?162013?(158.2?KiB)RX?errors?0??dropped?2269??overruns?0??frame?0TX?packets?177??bytes?16706?(16.3?KiB)TX?errors?0??dropped?0?overruns?0??carrier?0??collisions?0device?interrupt?17??lo:?flags=73<UP,LOOPBACK,RUNNING>??mtu?65536inet?127.0.0.1??netmask?255.0.0.0inet6?::1??prefixlen?128??scopeid?0x10<host>loop??txqueuelen?1??(Local?Loopback)RX?packets?96??bytes?8308?(8.1?KiB)RX?errors?0??dropped?0??overruns?0??frame?0TX?packets?96??bytes?8308?(8.1?KiB)TX?errors?0??dropped?0?overruns?0??carrier?0??collisions?0virbr0:?flags=4099<UP,BROADCAST,MULTICAST>??mtu?1500inet?192.168.122.1??netmask?255.255.255.0??broadcast?192.168.122.255ether?52:54:00:7e:e7:ca??txqueuelen?1000??(Ethernet)RX?packets?0??bytes?0?(0.0?B)RX?errors?0??dropped?0??overruns?0??frame?0TX?packets?0??bytes?0?(0.0?B)TX?errors?0??dropped?0?overruns?0??carrier?0??collisions?0

7.2.使用網(wǎng)橋管理命令查看

#?brctl?show bridge?name?????bridge?id???????????????STP?enabled?????interfaces virbr0??????????8000.5254007ee7ca???????yes?????????????virbr0-nic

9.5.安裝過程

9.6.安裝完畢后結(jié)束掉kvm進(jìn)程

#?kill?-15?5168

9.7.重新啟動(dòng)，啟動(dòng)Guest虛擬機(jī)，修改啟動(dòng)方式為硬盤 -boot c ，去除光盤資源

#?/usr/libexec/qemu-kvm??-m?512?-smp?1?\ -drive?file=/home/kvm/p_w_picpath/cent7_1.qcow2?\ -net?nic,vlan=2,model=e1000,macaddr=52:54:00:12:34:56?\ -net?tap,vlan=2,ifname=tap10,script=no?-boot?c?\ -vnc?192.168.1.3:1??--daemonize

10.安裝完成
