Generally, virtual machine image files are directly stored in an IMG image file or directly partitioned using/dev/SDA. However, if the Virtual Machine partition is "broken", it will be hard to recover. Qemu supports qcow2, an image format that allows you to create Incremental Images. This allows you to store modifications in new files and protect the original image when an error occurs. This function is very useful,[Xen seems to support qcow2, to be

After a long time ago, I accidentally saw it again and recorded it for sharing. Background:The SMS function is provided to the customer's Development System.

If you have special requirements for independently modifying the xen
