创建虚拟机 需要打开 BIOS 观察下 CPU 高级选项中的 virtinst 是否打开
否则
虚拟机类型中 没有 kvm 有些时候 用qemu 虚拟系统 会报错误 /dsp 关闭selinux 可以继续
yum install kvm qemu virt-manager
Install KVM
[1] Install KVM
[root@dlp ~]#
yum -y install qemu-kvm libvirt python-virtinst bridge-utils
[root@dlp ~]#
lsmod | grep kvm
kvm_intel

[root@dlp ~]#
/etc/rc.d/init.d/libvirtd start
Starting libvirtd (via systemctl):
[ OK ]
[root@dlp ~]#
chkconfig libvirtd on
[2] Configure Bridge networking for KVM virtual machine.
