我安装了CentOs 7的虚拟机之后，我安装了CentOs 7作为主机。
我不得不提问
1.如何从cli上的主机上看到磁盘客户机。 就像当我运行“virsh列表 – 所有”
2.如何从cli创build添加另一个磁盘而不创buildxml段落
谢谢

mkdir -p /mnt/ubimage losetup /dev/loop0 /opt/ub.img kpartx -a /dev/loop0 mount /dev/mapper/loop0p1 /mnt/ubimage
如果您的VM已经安装了LVM。 您需要应用其他步骤：
vgscan vgchange -ay mount /dev/VolGroupName/LogVolName /mnt/ubimage
