vmxnum=$(egrep '(vmx|svm)' --color=always /proc/cpuinfo -o |wc -l)
cpunum=$(cat /proc/cpuinfo | grep processor | wc -l)
if [ $vmxnum -eq $cpunum ];
then
echo "cpu not support"
exit 1
else
echo "ok ,continue "
fi
2 安装软件包
apt-get install qemu-kvm libvirt-bin bridge-utils -y
modprobe kvm_intel
if [ $? -eq 0 ];
then
echo "you must motify this in bios"
fi
ERROR: could not insert 'kvm_intel': Operation not supported
或者
dmesg | grep kvm | grep -c "disabled by bios"
root@MySQLmaster:~# dmesg | grep kvm
[1031219.203545] kvm: disabled by bios
[1031343.376838] kvm: disabled by bios
需要开启bios对虚拟化的支持
3 修改网络配置：
cp /etc/network/interface /etc/network/interface.bak
cat >> /etc/network/interface < auto lo br0 iface lo inet loopback iface eth4 inet manual iface br0 inet static #bridge_ports eth0 eth2 bridge_ports eth4 address 192.168.4.102 netmask 255.255.255.0 gateway 192.168.4.233 bridge_stp off bridge_waitport 0 bridge_fd 0 EOF /etc/init.d/networking stop && /etc/init.d/networking start 4 修改内核参数： cat >> /etc/sysctl.conf < #for kvm net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 EOF sysctl -p 5 生成磁盘镜像文件： qemu-img create -f raw /data/debian7.img 10G 6 开启vnc vim /etc/libvirt/qemu.conf vnc_listen = "192.168.4.102" /etc/init.d/libvirt-bin restart 7 安装系统： virt-install -d -n vm_kvm -r 2048 --disk path=/data/debian7.img,bus=virtio,cache=none --network bridge=br0,model=virtio --cdrom=/data/software/debian-7.4.0-amd64-netinst-bnx2-auto.iso windows通过vnc连接： 安装debian7. 待续... 参考： http://hi.baidu.com/zhangfan879/item/eec87ee59764443c86d9de02 ....
