    Put it under load and it does some strange things sometimes.

    My unit has 2 2008 R2 VMs, an XP VM, and 2 Debian VMs in operation all the time. It works WONDERFULLY. Until the hard disks run out of read/write time.

    Also, RAM is an interesting balance as I said before, if you add too much to a given VM you can actually reduce performance of everything on the box. In the case of running things in a hypervisor, you DON'T want drive caching at all.

    That's why when i create the vm i tell it that all paging is done to RAM not to the disk.. You can also set vm.swappiness=0 and that eliminates the kernel's predilection to swap. At that point it won't usually swap until ALL ram is actually exhausted.

    Yes but that doesn't help when you're filling ram with useless bits. But yes, that adjustment is rather important for live services like Untangle.

    And you can run VoIP through an Untangle in ESXi... but you'd better reserve enough hardware on that box such that Untangle is essentially running bare metal, just within the VM context.
