on Windows XP SP3 host I am using VirtualBox 3.1.4 and running guest Ubuntu 9.10.
When guest is started VirtualBox is using about 4% CPU. And at some stage guest freezes (I know this because music player inside guest stops playing and any click on any window does not produce any response). When I switch back to host I see 35-40% of CPU is being used by VirtualBox process. The only way I can solve the problem is to power-down guest.
I attached log file from this computer.
P.S. The same problem I have on Ubuntu 8.04 LTS host and Windows XP guest running VirtualBox 3.1.2 in headless mode, but on this computer guest freezes one's per two to three days, but always when some minor task is done.
I never experienced such a problem using VBox pre 3.1 release.
Any one else having the same problem?
