The virtual machine cannot boot into the system after a restart. What should I do?

Symptom

The virtual machine cannot boot normally and displays a Give root password for maintenance prompt.

Cause

The virtual machine fstab is configured for automatic disk mounting, but the disk device name has changed, preventing the virtual machine from mounting automatically.

Solution

• Run the following commands in the virtual machine to mount the disk:

  # Get disk UUID
  [root@localhost ~]# ll /dev/disk/by-uuid/
  # Mount the directory
  [root@localhost ~]# mount /dev/disk/by-uuid/$disk_UUID /zstack_ps
  # Configure automatic mounting using disk UUID
  [root@localhost ~]# vi /etc/fstab
