I wouldn't worry about *duplicate cache* as far as disk goes at all.

This duplicate cache is only going to benifit your vm, if the host machine has enough left over ram. If the host machine doesn't have enough ram, there won't be any cache to worry about. I think this also only applies when using a file based drive, where if you use a raw partition it doesn't get cached, cause the vfs is bypassed.

My primary "concern" was the VM cache. My thought was since the host was caching, there was no need for the VM to try to allocate precious VM memory for cache purposes. The goal "obviously?" being to allocate as much RAM as necessary for efficient Dovecot functioning in the VM and avoid any swap-to-disk issues.
