Hi,
on Windows XP SP3 host and Ubuntu 9.04 I had VirtualBox 2.2.2 working well without any problem.
Then I did the following:
1. shutdown virtual guest
2. installed VirtualBox 2.2.4 over the existing installation.
3. rebooted Windows host
4. opened VirtualBox GUI
5. deleted all VirtualBox log files to make sure there is no errors in logs.
6. selected Ubuntu guest and clicked Start button from tools bar menu.
The error displayed: "Cannot access the kernel driver! Make sure the kernel module has been loaded successfully." Then only Abort button available and click on it displayed error: "Failed to open a session for the virtual machine..."
See attached pictures.
I have checked the log files but there was no log file created! Very strange.
Has anyone got the same problem?
Regards
