| 8 | In server environments with many VMs, the Guest Additions can be
|
|---|
| 9 | used to share physical host memory between several VMs. This
|
|---|
| 10 | reduces the total amount of memory in use by the VMs. If memory
|
|---|
| 11 | usage is the limiting factor and CPU resources are still
|
|---|
| 12 | available, this can help with running more VMs on each host.
