The virtual machine pauses automatically. How do I resolve this?

Cause

The Local Storage disk, host system disk, or Data Storage is full, causing a virtual machine I/O error and automatic pause.

Solution

• Log in to the host and run virsh domblkerror $vm_uuid to view details.

  • If the Local Storage disk is full, free up space on the corresponding Data Storage host by removing idle business virtual machines or disks, or deleting logs.
  • If the host system disk is full, delete unnecessary files or logs.
  • If the Data Storage is full, delete idle business virtual machines or disks.
