I have Zimbra running as an Ubuntu VM on an OpenSolaris host with VirtualBox. This works well, but since I run both MySQL and Memcached on the host OpenSolaris OS, it would be more appropriate to use these instead of virtualising them again.
Now, is there a simple way to do this? I talked to someone on IRC that said no, don't do it, since it'll make upgrades harder etc.
If there isn't a good way to do this, perhaps it should be added? It shouldn't be too hard to set in a config file that please use /this/ server for MySQL and /that/ server for Memcached etc.
