My guest is a vm ubuntu 16.04 on Virtualbox with host windows. Once I start vm, it goes to pause automatically several times. Without changing the amount of memory for guest, is there a way to disable auto-pause ? (This state is a warning from VB to let me know windows might experience lack of memory) Kian William

I notice this situation on my CentOS VS while I have another Ubuntu VS opened for weeks. When I close that Ubuntu, CentOS stop auto pause. So I think it maybe the memory issue.

Using different RAM types, memory caching applications or other host techniques that affect access to physical RAM may affect RAM allocation of the guest in VirtualBox.

If we can't avoid such techniques in the host we may try to enable pre-allocation of RAM for a virtual machine with the following command:

VBoxManage setextradata <vmname> VBoxInternal/RamPreAlloc 1

Another cause for issue with RAM allocation may come from guests that had memory ballooning enabled.
