Online migration to OpenVZ - live video
During the discussion of online migrations with Shchors, 2 videos were born with the online migration of OpenVZ containers between nodes.
In the first video, the container in which nginx is running migrates, requests from ab to two threads go to / status, requests are written to the log, i.e. the size of the occupied space is dynamically changed.
')
In the second, the container in which the table is copied inside the mysql is migrated (select into blabla2 select * from blabla1), the size of the base is 350mb, 850k records.
The main host machine is core quad q6600 with Vista, VMware virtual machines are running inside, and Linux already has OpenVZ in them.
3e - from virtualka to vmware to virtual hyper-v, different physical machines, via switch length 100mbit
