We are looking to use virtualisation on a new project to help with
deployment etc.
One of the servers will be database server, specifically the RDBMS will
be PostgreSQL.
Therefore on that server will be the host Linux OS with a guest Linux
OS running on Xen. The guest OS is the one with the database.
My question is
If the database is running on a guest OS with its own disk space etc
and we then wish to deploy and run a newer image due to a software change or
something what happens to the data in the database on the older image? Is
this lost?
How can the new image pick up the existing data? Am I having a
fundamental misunderstanding?
Thanks in advance for your responses.
