Hi All

I've been using VirtualBox for 4 years without incident and yet recently when I start my Windows XP guest it hangs (as in no activity) and one of the host CPU's is at 100% which shows as being used by VirtualBox VM.

I was running 4.2.12 and thought it might be a bug with that, but having upgraded to 4.2.18 it still exhibits the same problem. Now I used this machine just last week without a problem and as far as I can tell nothing has changed. No windows updates no Mac OSX updates, so I can't help wonder what is going on.

Below is the config file and attached is the log. Hopefully someone can help.

UPDATE

Well the 100% cpu issue and the hanging finally stopped after 2hours and the VM is now fine. Very strange, not sure what might be causing this as there doesn't appear to be anything in the logs.

Sounds like antivirus.

I deleted the VBox log file you posted, to save space since there seems to have been no actual VBox problem.

Sorry to point out the obvious here, but it wasn't antivirus as I checked, the system was responsive for a short while then it stopped. I ran task manager in the Guest and nothing was hogging CPU on the guest. Oh not only that but there was no activity on the HDD or the network.

Thanks

If this might help, I had no troubles with 4.2.16 and XP SP3.
I'm installing 4.2.18, and see what happens.

I've noticed the same behavior on Linux hosts. The task manager in the guest however shows 100% cpu.
(svchost) nice huh ? tells you a lot. I have noticed this pattern though. This only happens when the guest
has not been up for several days.

use process explorer from MS and it will show you that the wuauserv is using 100% CPU. Doing this on metal as well. Something borked in the automatic updates from MS and can take as long a a few hours to complete a scan to update. Turn automatic update off and see if it works properly. If so turn it on and go to dinner and a movie.

I have already turned off auto update. Still see the same behavior.
