Hi,

Having attended a few PGCons, I've always heard the remark from a few presenters and attendees that Postgres shouldn't be run inside a VM. That bare metal is the only way to go.

Here at work we were entertaining the idea of running our Postgres database on our VM farm alongside our application vm's.  We are planning to run a few Postgres synchronous replication nodes.

Why shouldn't we run Postgres in a VM?  What are the downsides? Does anyone have any metrics or benchmarks with the latest Postgres?

Thanks!

Lee Nguyen
