5. kvm问题
kvm安装
apt-get install kvm libvirt-bin
检查kvm是否可用
kvm-ok
dell r610机器出现下列问题:
root@ubuntu:/etc/init.d# kvm-ok
INFO: /dev/kvm does not exist
HINT: sudo modprobe kvm_intel
INFO: Your CPU supports KVM extensions
INFO: KVM (vmx) is disabled by your BIOS
HINT: Enter your BIOS setup and enable Virtualization Technology (VT),
and then hard poweroff/poweron your system
KVM acceleration can NOT be used
r610本身支持kvm但需要打开BIOS设置
PROCESS ... => VIRTUALIZATION TECHNOLOGY => ENABLE
配置OK!
测试kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
