Hi. Upgraded from VBox 4.2.0 to 4.2.4 today and installed the corresponding extensions. Immediately, I noticed that my primary guest (WinXP with guest additions) is unusably slow. Guest boot times went from 20-30 seconds to well over 5 minutes during which guest disk activity was strangely intermittent. Once booted, the guest remained unusably slow. 5 seconds to refresh the desktop, 8-10 seconds to open the 'Start' menu, etc. 'top' running on the host machine indicated that VirtualBox process was pegging the two CPUs allocated to it. I saw no abnormal network activity and /proc/interrupts didn't indicate abnormally high interrupt levels.

After rebooting the host system, things started behaving more normally. This led me to believe that perhaps the upgrade process left one of the old 4.2.0 kernel drivers loaded and that was conflicting with the new 4.2.4 stuff. Problem solved, I thought. However, after about 4 hours, the guest was back to running unbearably slow with VBox once again pegging both its CPUs. Since I can't afford to reboot the host machine every 4 hours, I guess I'll go back to VBox 4.2.0.

Anybody seen this kind of behavior following a VirtualBox upgrade?

Host system details:
Fedora 14 running 2.6.35.14-106 (yeah, yeah, it's old. I know)
8GB ram, 4-core i7 processor.
VBox v4.2.4 with corresponding extensions installed

Guest details:
WinXP with guest additions installed
VM settings: 2 CPUs, 2GB RAM, 128MB video memory, NAT networking

VM log file please, as a zipped attachment. The VM log file is called "VBox.log", and can be found in the "Logs" subfolder of your VM folder.

I'm having a similar problem only a reboot doesn't help. It's mostly the video refresh is really slow and stuttered. I get mouse trails when I drag my mouse across the screen. I'm running the 64 bit 4.2.4 rpm on FC17. Any advice? Logs attached.

• First we don't support the RPMfusion version of VirtualBox.
• Next you do not have enough free available memory.
• Finally you will have a lot better results if you enable VT-x in your bios.
