Install and configure an openstack Virtual Machine. When you need to modify the ip address, you can modify the ip address in the database. Since many tables are created when the openstack environment is configured, the local ip address is configured. Therefore, when the local machine needs to modify the ip address, it needs to synchronize all the environment-rela

When using nova resize to modify the virtual machine configuration, the migrate code is actually called. By default, when Resize is executed, the disk image and the backend image are first merged into raw and then converted into qcow2. It also performs the Migration action. The whole process will consume a considerable amount of time, and we generally only need to modify the CPU and memory size, and do not need to merge images, but do not need to perf

On the other hand, virtual machine migration is divided into cold transfer and heat transfer, the so-called heat transfer of the mother's words is: thermal migration (Live migration, also known as dynamic migration, real-time migration), that is, virtual machine save/Restore (Save/restore): The entire virtual machine running state intact, At the same time can be
