Host hangs under high load

$

Hello all,

 

I have a problem with VMWare Workstation 2013. I'm not sure if the same problem exists under 9.0.2.

 

The problem is, when the load on my host is high, my input freezes, if I have VMWare Workstation running. If I do not have VMWare Workstation running at the time, my host is "just busy", but once CPU cycles come free, it starts responding again.

 

When VMWare Workstation is running a VM (just opening the GUI doesn't do this), and I move my mouse over the "desktop" of my VM (so it tries to grab input), my input no longer works (no mouse, no keyboard). Only solution is a hard reboot.

 

It's not swapping (no disk activity),the host is not starved for resources (plenty), and it does not occur when Workstation is not running a VM. In my opinion, it seems to be related to the "grabbing" of the mouse. If I have music playing on my host desktop, it keeps running, so not all processes freeze. Just my mouse and keyboard which no longer respond.

 

VMWare.log only reports this:

2013-09-02T11:59:28.736+01:00| vmx| I120: ToolsUpdateManifestInfoWorkerThreadDone: Updating the manifest info.

2013-09-02T11:59:35.084+01:00| vmx| I120: LOADAVG: 4.01 3.44 2.36

 

Because of the hard reboot, I'm not sure if there was still some logging in my FS cache.

 

Host: Ubuntu 13.04 with 3.11 rc7 kernel.

pCPU: 2 core, HT enabled (4 cores)

pRAM: 8 GB

 

Guest: Windows XP X64

vCPU: 2 cores

vRAM: 1 GB

 

Steps to reproduce:

- Open VMWare Workstation

- Start a VM

- Produce load on host machine

- Move the mouse over the desktop in the VM

 

Expected results:

- VM grabs input, and I can ungrab it by pressing Ctrl-Alt

 

Actual results:

- Host machine seems "hang", no longer accepting input from keyboard / mouse
