Ticket #1299 (closed defect: duplicate)
virtualbox consumes all CPU -> IO-APIC
|Reported by:||brian||Owned by:|
I have installed the PUEL 1.5.6 version from your download site and have a WindowsXP guest running on a Ubuntu Gutsy Linux host. The guest runs fine except for two issues:
- Mouse integration does not work. Virtualbox thinks that it should. I get the two little
green arrows on the mouse, however any mouse activity in the guest window makes the guest's mouse cursor simply move in a down-and-to-the-right diagonal line. There is a direct correlation to mouse events and mouse cursor movement in the guest -- that is, even though the mouse cursor in the guest only moves in a diagonal-down-and-right line, it only moves in that direction when I generate mouse events by moving my mouse.
- VirtualBox consumes 100% of a CPU, while it runs this guest, even when the WindowsXP guest is
idle. I've straced the VirtualBox process while this is happening and there seems to be an extraordinary number of ioctls to the file descriptor that the VirtualBox process has open to the vboxdrv driver. I posted to the mailing list about this and the strace details can be found in that posting.
