Guest stop to run

[cucca]

Hello All,
i have a guest linux machine, that stop to run! I don't remember if something has changed because i use it on several host, but the error i get in the log is:

UIFrameBufferQImage::resizeEvent: Resizing to FALLBACK buffer due to format is invalid..

i tryed to update VM, guest additions, extension pack but still not booting....

here with attached the log file..

thanx in advance!

What precisely is the guest you are trying to run? OS name? Version? 32bit or 64bit?

Also, please provide a complete log file, not the log of a session that was still in progress. I.e. shut down the VM before grabbing the log.
