Hello,

This is a very strange problem, and it has happened me on two separate machines under only one user account (installation under another user account was absolutely fine).

The host OS is Centos 5.4 in both cases. VirtualBox V 3.0.10 (installed from rpm VirtualBox-3.0.10_54097_rhel5-1.x86_64.rpm) in both cases. The VM is to run Win XP (official licensed version) in both cases.

What happens on installing the OS (Win XP) is that the machine goes down. Once it 'sleeps', it cannot be 'reawakened' - no rection from mouse or keyboard. The OS is still functioning as I can ssh from another machine.

Any ideas why/how this is happening? And how I can prevent it. :-(

Thanks

actually, VirtualBox now continuously hangs the entire system, no matter which machine I use to access this user account... :-( all other user accounts work fine...
