There are several things going on here. The memory setting in the configuration editor adjusts the memory that a particular virtual machine thinks it has. But, you can be running several virtual machines at once. The memory limit in the preferences pane gives how much memory is preallocated for all the virtual machines you have running. I leave it on "Automatic." The preallocation option creates a 1.5 GB file on your hard drive when you fire up Parallels to make sure a virtual machine can access RAM without restarting Parallels, if you want to increase its allocation. I leave it unchecked. > Is it necessary to put anti virus software on windows in Parallels? > I'm > doing very little is any surfing. I wouldn't hang XP out on the Internet without protection. Here's why [1]: A story on CRN tells the grim tale of the lifespan of an unprotected machine - according to information from Sophos, a machine on the Internet averages 12 minutes before it?s infected with a worm. The Internet Storm Center estimates the time at 34 minutes, while an AvanteGarde study over two weeks calculated an average 4 minutes before an XP SP1 machine was compromised by bots. Take it as you will ? even being very conservative, 34 minutes to infection is unacceptable. If your machines and XPE devices aren?t protected with a firewall and some good anti-virus software, you?re in for trouble.
