virtualbox.org

Hello,

I've seen posts about this now and then, and I've checked the bugzilla.

I'm running a P4 w/ hyperthreading enabled.
2.6.26-1-686 #1 SMP Wed Jul 30 20:02:15 <--Stock Debian

It seems that with any guest windows 2k or Linux, if I have USB enabled, my CPU usage skyrockets. Sometimes over 100% (2 cores right)

Is this ever planned on being fixed. I've downgraded to 1.6.0 and still see the problem.

Is it perhaps my own system? I feel this maybe the more likely culprit.
What tweaks do I need on my Linux host to stop the CPU spikes if it is my system.

Thank You,
btanoue

I think I am seeing the same problem. I turned off usb2 and its a bit more stable, but it still locks up, with high cpu usage

when i strace, it seems to be read fd 21 and 29 and failing, these are unix sockets and fifo, looks like something is broken.

KeyzerSuze,

If you can tell me how to run strace to profile virtualbox, I can also check to see if I am seeing the same thing you are.

run

ps -u "$(id -u)" ww

to show you al the processes running under your userid there will be a VBox.. appplication running finds its pid and then run strace -p <pid>
