5.3.6 Pausing a VM
If you need to free up CPU cycles on the host machine, you can pause some of the VMs. This option
writes the current state of the VM to the host machine’s RAM so that it can be recovered by
resuming the VM . A paused VM can also be moved to a suspended state without resuming it first.
1
In the VM Client , click the Virtual Machines view.
2 Do one of the following:
Š Select the VMs to be paused, then click the button.
Š
Select the VMs to be paused, then click Actions > Pause .
Š Right-click the VMs to be paused, then select Pause .
Each VM’s state is saved to RAM on the host machine.
WARNING: If you use the Restart option to reboot a VM, its previous state is lost. If you want
to recover its previous state, use the Resume option , which reads the VM information from the
host machine’s RAM.
Also, if you reboot the host machine, the VM’s state is lost, because it was saved to the host
machine’s RAM. To prevent the loss of a VM’s state when you need to reboot the host
machine, first use the
Suspend option to suspend the VM.
5.3.7 Resuming a Paused VM
1 In the VM Client , click the Virtual Machines view.
2 Do one of the following:

The previous state of the VM is restored from the information that was written to the host
machine’s RAM when the
Pause option was used.
If the VM’s console was open, it reopens automatically.
5.3.8 Suspending a VM
If you need to temporarily free up RAM on your host machine, or to save the state of any VMs
running when you reboot the host machine, use the
Suspend menu option. This option writes the
current state of the VM to the host machine’s hard drive so that it can be recovered by resuming the
VM .
