##5.2 Nova计算节点

# compute 安装

#5.2.Nova-compute.sh

#基本配置：

#关闭selinux、防火墙

#更换阿里源、升级、重启、时间同步

#hostname设置

#安装OpenStack库

#安装配置Nova

yum install -y openstack-nova-compute

yum install -y python-openstackclient openstack-selinux

#设置Nova实例路径(磁盘镜像文件)

Vdir=/XLH_Data/nova

VHD=$Vdir/instances

mkdir -p $VHD

chown -R nova:nova $Vdir

#使用QEMU或KVM ,KVM硬件加速需要硬件支持

[[ `egrep -c '(vmx|svm)' /proc/cpuinfo` =  ]] && { Kvm=qemu; } || { Kvm=kvm; }
