I have looked through the forums and can see this error has been round for a while now, with no fix being made available. A couple of posts have said to try sysinternals cacheset utility. I have tried this (setting max size to 10% of physical memory) but still get this error. This error manifests itself after I have started 5 guests (details below) which run ok - when I start the 6th guest (it doesnt matter if its a windows or linux guest) then the guest VM is paused with the HostMemory low error. There is plenty of memory available to the guest according to taskmanager/resource monitor (4GB ). Please could somebody spare the time to look into this problem in order to provide a fix - I would rather stay with VirtualBox but will have to go over to VMware if there is no resolution forthcoming.
