The guest OS is 32-bit Debian Etch (KDE), the host AMD64 X2 5200+. Kvm runs in SDL, command line: kvm -m 80 -hda disk.qcow
All of this happens with kvm trunk. Quite often, once or more per hour, the guest hangs/freezes, consuming nearly 100% kernel cpu (user cpu usage is 0,00%) on the host. I use the guest for browsing the net and irc, so it is used many hours/day for real work. The qemu monitor in the guest still works nicely, thoughm such as stopping and starting the cpu, inspecting registers etc. Looking at guest $eip, it seems to be in a loop at about 0xc011ac70 - 0xc011b508. One can also release the mouse grab and enter the grab again. I haven't found a way to make the guest exit the cpu loop. Output from kvm_stat when the guest freezes is: kvm statistics exits 0 0 halt_exits 20050310 0 invlpg 0 0 io_exits 170429877 0 irq_exits 0 0 irq_window 0 0 mmio_exits 9859649 0 pf_fixed 285553491 0 pf_guest 14202518 0 request_irq 489317 0 signal_exit 3584242 249 tlb_flush 22082315 0 The keyboard/mouse problems occure much more often in full screen mode. Very often (nearly every minute), the guest mouse will do something random without warning, like: - move instantly to some other location on the screen - click a mouse button (any of the three buttons). (If mouse happens to be over a web browser window and button 2 is pressed, firefox will try to treat the clipboard text as an url and go to that page, so this sometimes manifests itself in the web browser doing seemingly random stuff). Current keyboard problems are: - keys sometimes repeat on a normal keypress and don't stop until another key is pressed (nearly every minute, sometimes more often) - any of the Ctrl, Shift and Alt seem to get automagically pressed and stuck (several times per hour) ------------------------------------------------------------------------- Using Tomcat but need to do more?
