KVM（二）QEUM安装

安装：
（1）确保CPU支持HVM

# grep -o -E ‘svm|vmx’ /proc/cpuinfo –color
vmx
vmx
vmx
vmx
svm是adm的
vmx是inter的

（2）装载模块

# modprobe kvm
# modprobe kvm_intel
# lsmod | grep “kvm” –color

（3）验证

# ls /dev/kvm -l
crw-rw—- 1 root root 10, 232 Dec 23 14:37 /dev/kvm

（4）安装管理工具栈(qemu-kvm)：
# yum grouplist | grep -i “virtualization” –color
Virtualization：
qume-kvm
Virtualization Client:
python-virtinst,virt-manager,virt-viewer
Virtualization Platform
libvirt,libvirt-client
Virtualization Tools
libguestfs
安装工具栈：
# yum -y install qemu-kvm

# rpm -ql qemu-kvm | grep -i “/usr/libexec/qemu-kvm”
/usr/libexec/qemu-kvm

# ln -sv /usr/libexec/qemu-kvm /usr/bin/
`/usr/bin/qemu-kvm’ -> `/usr/libexec/qemu-kvm’
