HostMemoryLow error - windows 2008r2 x64 host

[lenny]

Hi,

I'm getting the dreaded HostMemoryLow message on a windows host. 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.

Did you ever install an older version of VirtualBox, namely 3.2.12 and was it different with this version?

Please could you attach the complete VBox.log file?

And does this happen as well if you disable the preview function in the GUI?

The previous versions we have had running which also experienced this error were: 4.0.0 3.2.8 3.1.6 ( this was on w2k3 server 32 bit but error popped up after running 3 vms)

I disabled the preview function by right clicking in the GUI details area and un-ticking preview (is this the correct way to disable preview ?) , and then managed to recreate the error - see full vbox.log attached.

If you need me to test against 3.2.12 or to provide any other info/diagnostics then please let me know.

hmm the last post the formatting didnt work as expected. It was only version 3.1.6 which we ran on w2k3 32 bit, the others were on the current platform w2k8 x64.

Please reopen if still relevant with a recent VirtualBox release.
