- Memory_overcommitment abstract "Memory overcommitment is a concept in virtualization that covers the assignment of more memory to virtual computing devices than the physical machine they are hosted on actually has. This is possible because virtual machines do not necessarily use as much memory at any one point as they are assigned, creating a buffer. If four virtual machines each have 1GB of memory on a physical machine with 4GB of memory, but those virtual machines are only using 500MB, it is possible to create additional virtual machines that take advantage of the 500MB each existing machine is leaving free. memory swapping is then used to hande spikes in memory usage. The disadvantage of this approach is that memory swap files are slower to read from than 'actual' memory, which can lead to performance drops.".
