I don't like real machines anymore. I like to have everything virtual.
Hardware dies? Buy a new one, minimum install, restart my virtual machines and I am done.
Hardware is too slow? Buy a new one, minimum install, restart my virtual machines and I am done.
New system needed? Don't by new hardware, just create new virtual machine.
I thought like this, too. Not anymore.
I used to have virtual Linux host machines on my real server for this and for that because I thought, as you, that when the hardware dies I have little effort and my VM is ready again.
I did that until I have actually seen how much resources and with that energy is wasted doing that.
After weeks my server system was unresponsive because after a while all resources were exhausted at the huge speed disadvantage VMs have.
VM, yes. Where it makes sense. But not if you can structure your stuff intelligently (for backup and simple recovery) on a real hardware.
