centos 7.5安装计算节点nova组件报错

1.报错信息:

Failing package is: 10:qemu-img-ev-2.12.0-33.1.el7_7.4.x86_6

2.原因:

缺少virt的yum源,在yum源中添加:

[virt]
name=CentOS-$releasever - virt - mirrors.aliyun.com
failovermethod=priority
baseurl=http://mirrors.aliyun.com/centos/$releasever/virt/$basearch/kvm-common/
gpgcheck=0
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
