Publication number: US20220012087A1
Application number: 17/485,071

Abstract:
A migration method and a migration system of a virtual machine are disclosed. The method includes: a virtual machine detecting whether a migration instruction is received, wherein the virtual machine runs on a first processor of a first host machine; the virtual machine calling and obtaining video memory data generated in the first processor if the migration instruction is detected; and the virtual machine migrating the video memory data to a second processor of a second host machine. The present disclosure solves the technical problem that a virtual machine using a GPU pass-through mode fails to perform a live migration between host machines in the existing technologies.

Publication number: US20220006617A1
Application number: 17/481,131

Abstract:
Disclosed are data storage and verification methods and a device executable in a trusted execution environment. The data storage method comprises: encrypting, using a first key, user data and version information of the user data to generate first ciphertext, and storing the first ciphertext into a general storage space (S310); generating verification information of the user data (S320); and storing the version information and the verification information into a secure storage space (S330). The present disclosure effectively prevents version rollback of user data.
