Oracle VM does not currently support the overcommitting of guest Virtual Machine (VM) memory.
Only available physical memory on Oracle VM Servers (dom0) can be allocated to guests (domU).
Using Oracle VM Manager, for example, it is possible to increase the memory configuration of guest VMs to have more memory than is physically available on Oracle VM Servers. Doing so, however, may give the false impression that a guest may be running with more memory than it really is.
The memory configuration of one or more running guest VMs was dynamically increased.
