In FusionCompute, when the running host where the virtual machine is located fails, the resource...

Only when the virtual machine network card is in "SRIoV", "PF" or "PCI" pass-through mode can the hot migration function be supported.

During virtual machine live migration, if the migrated virtual machine has a large business volume or a large memory usage, it will lead to the hot migration time is longer, and it is recommended to perform hot migration when the business volume is small

When the load of most hosts is too light, the virtual machines can be integrated by live migration to reduce the number of hosts. Improve resource utilization and achieve energy saving and emission reduction

By default, the system interface will prompt a timeout when the hot migration time exceeds 12 hours, but the internal heat. The migration task timeout period is 24 hours, and the live migration will not be terminated until the system times out.
