Which virtualization method is more suitable for a database server?

Question

Database administration

There is a MySQL database of about 40 GB in size, it will have to be moved to a separate VPS / VDS.
Advise a server with which virtualization is better to choose with OpenVZ or with KVM? and why

Answer 1

It makes no sense to put the base files of a normally loaded DBMS into a virtual machine.
If you don’t care about inconvenience and I / O overhead, it doesn’t matter whether it will be a container or a virtual machine, it is more important on which disks it will all be located and whether the DBMS itself will be configured correctly in terms of performance.
See for example Melkij 's excellent answer - How to set up Postgres in Docker?
PS - add mysql to the tags, by the way. All of the above is true for him, although it is written about postgres.
