virtualbox.org

Hello,

the subject pretty much has it. I am running 3.0.0-beta1 on Windows XP SP2 host. Guest is Ubuntu 8.04 LTS. Doing "sudo reboot" in guest results in a mighty freeze just after the guest finishes shutdown sequence and says "Will now reboot"

Interesting that virtualbox.exe does not eat any CPU after that when hanged. However it can't be killed at all except that by physically powering off the host. It even survives logoff.

Except that that it seems to work well, and guest is finally able to utilize all cores for builds, which is great. Thanks a lot for Virtualbox!

Bump. Is this a known problem? Is there any additional information I could collect and provide to help nail it?

Thank you for participating in the beta test.
I seriously doubt that you will hear from the Dev's until the first of the week since this is a weekend.
I know that they will see it and if necessary will ask questions.

Well, a VBox.log file of such a hanging session would be appreciated. Not sure if this is a known problem.

I've just installed 3.0.0-beta1 again. Using 1 cpu, guest reboot worked fine. However, after I powered off the guest, specified 2 cpus, booted it again and then tried to reboot it, Vbox froze again. Vbox window is not repainting.

Vbox.log file is attached. I tried attaching to hanging virtualbox.exe from MSVC8. The call stack looks as follows. If that's of any help, I can install a custom debug version (say with symbols file) and provide you with a call stack from that one.

Just for reference judging from disassembly it seems to be hanging in a system call.

I've just installed beta2 and there's a bit of improvement!
Guest still freezes at reboot, however, it's now possible to kill Virtualbox.exe from Task Manager instead of by rebooting the host.

Screenshot and the log file are attached.
Thanks!

Should be fixed already.

Great news. Looking forward to beta3 and/or release
