Earlier today I fat figer a setting on a VM and instead of giving it 2GB I gave it 2GB. Now mind you the host only has 196GB of ram. I was a bit surprise the configuration even complete without error. I figure out the error after I powered up the VM and saw the error.
How could Vmware let this config succeed even though the host only had 196GB of ram. Yes I know you can over commit a host thanks to different memory saving techniques but this seem excessive. How was I even able to power up the VM? Maybe the host force other Vm to balloon?
It's called Over Commit!
VM and Host have swap files, and you and you can use Flash/SSD rather than slow spinning rust.
Never used Swap to Cache ? SSD ? or PCI-E flash cards ?
