Re: PostgreSQL and virtualization

["Medi Montaseri" <montaseri@xxxxxxxxx>]

Another view is...by the time you figure out all these virtualization solutions you can buy a used box for less than $100 (no monitor needed) and focus on the real test. By the way, in any  HA one issue will be the IP takeover on the surviving node. Under the IP will be the Mac address of the previous primary node which is now cached in switches and/or routers so a rebuild of the ARP cache will be needed. I am not sure how these virtualizations play the MAC game but minimally your test is tainted from that point of the view

You can also look at VirtualBox (www.virtualbox.org).  I my experience
it is as easy as VMWare and faster.
