The pause feature has certain restrictions and limitations.
You cannot switch to Unity mode when a virtual machine is paused.
When paused, a virtual machine does not send or receive network packets. If a virtual machine is paused for more than a few minutes, some network connections might be interrupted.
If you take a snapshot when the virtual machine is paused, the virtual machine is not paused when you restore that snapshot. Similarly, if you suspend a virtual machine while it is paused, it is not paused when you resume the virtual machine.
If you initiate soft power operations when a virtual machine is paused, those operations do not take effect until the virtual machine is unpaused.
While a virtual machine is paused, LEDs and devices remain enabled, but device connection changes do not take effect until the virtual machine is unpaused.
You cannot pause a remote virtual machine.
