一、安装kvm
1、先在blos中,开启vt-d功能
2、检查vmx看,是否开启vt-d
[[email protected] ~]# egrep --color ‘(vmx|svm)‘ /proc/cpuinfo
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts mmx fxsr sse sse2 ss ht syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts xtopology tsc_reliable nonstop_tsc aperfmperf unfair_spinlock pni pclmulqdq vmx ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm ida arat epb xsaveopt pln pts dts tpr_shadow vnmi ept vpid fsgsbase bmi1 avx2 smep bmi2 invpcid

3、yum install qemu-kvm virt-manager python-virtinst qemu-kvm-tools libvirt -y
4、配置桥接网卡
[[email protected] ~]# vi /etc/sysconfig/network-scripts/ifcfg-br0 DEVICE=br0 TYPE=Bridge ONBOOT=yes NM_CONTROLLED=no BOOTPROTO=none IPADDR=192.168.1.151 PREFIX=24 GATEWAY=192.168.1.1. DNS1=192.168.1.1 [[email protected] ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0 E=eth0 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=no BOOTPROTO=none BRIDGE=br0
#重启网络服务
service network restart
#查看ip
[[email protected] ~]# ifconfig br0 Link encap:Ethernet HWaddr E6:BB:52:CC:A2:13 inet addr:192.168.1.151 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::e4bb:52ff:fecc:a213/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:10 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:636 (636.0 b) eth0 Link encap:Ethernet HWaddr 00:0C:29:3C:A4:3F inet addr:192.168.1.151 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe3c:a43f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:75470 errors:0 dropped:0 overruns:0 frame:0 TX packets:87895 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4908230 (4.6 MiB) TX bytes:103752663 (98.9 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:1 errors:0 dropped:0 overruns:0 frame:0 TX packets:1 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:76 (76.0 b) TX bytes:76 (76.0 b) virbr0 Link encap:Ethernet HWaddr 52:54:00:7D:25:D1 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:31 errors:0 dropped:0 overruns:0 frame:0 TX packets:9 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2162 (2.1 KiB) TX bytes:1324 (1.2 KiB)
5、启动libvirtd服务
/etc/init.d/libvirtd start /etc/init.d/libvirtd status
6、安装虚拟机
[[email protected] ~]# cd /opt/
#创建分区
qemu-img create -f raw /opt/kvm.raw 10G
#加载镜像
dd if=/dev/cdrom of=/opt/centos66.iso
ls -lsh /opt/centos66.iso
#安装centos6.6
virt-install --virt-type kvm --name centos6.6 --ram 1024 --cdrom=/opt/centos66.iso --network network=default --graphics vnc,listen=0.0.0.0 --noautoconsole --os-type=linux --os-variant=rhel6 --disk path=/opt/kvm.raw
#清空iptables
iptables -L
iptables -F
备注:必须清空防火墙,否则无法连接TightVNC软件
7、查看监听端口
[[email protected] ~]# netstat -ntlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 192.168.122.1:53 0.0.0.0:* LISTEN 1744/dnsmasq tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1442/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1547/master tcp 0 0 0.0.0.0:39453 0.0.0.0:* LISTEN 1195/rpc.statd tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1175/rpcbind tcp 0 0 :::36693 :::* LISTEN 1195/rpc.statd tcp 0 0 :::22 :::* LISTEN 1442/sshd tcp 0 0 ::1:25 :::* LISTEN 1547/master tcp 0 0 :::111 :::* LISTEN 1175/rpcbind [[email protected] ~]# ps aux | grep kvm root 771 0.0 0.0 0 0 ?

8、安装windows连接vnc软件
软件名称:TightVNC viewer 2.8.8
#系统安装过程
省略。。。
#查看cpu分配缓存
[[email protected] ~]# lscpu -p # The following is the parsable format, which can be fed to other # programs. Each different item in every column has an unique ID # starting from zero. # CPU,Core,Socket,Node,,L1d,L1i,L2,L3 0,0,0,0,,0,0,0,0 1,1,0,0,,0,0,0,0 2,2,1,0,,1,1,1,1 3,3,1,0,,1,1,1,1
