#2258 fixed Solaris 10u5 guest hangs and consumes 100% CPU Shane Hjorth
Description

Running Virtualbox 2.0.2 on a Sun Ultra 24 running Ubuntu 8.04 (64bit) and I am finding stability to be a real problem when Intel VT-x is enabled which in turn allows me to run Solaris 10u5 x86 in 64-bit mode.

Running with VT-x disabled (same guest no running in 32-bit mode) is however stable.

After a period of time (30minutes+ depends on activity on the guest itself) when VT-x is enabled the Solaris 10u5 (64-bit) VirtualBox process will become non-responsive (hang) and CPU usage will shoot up to 100%.

The spinning thread is looping in the following call:

(gdb) where

I have tried a number of troubleshooting steps to solve this issue:

  • patched the Ultra 24 bios to the latest available.
  • Upgraded virtualbox from 2.0.0 -> 2.0.2
  • Ran the Solaris 10u5 system with and without VBox tools installed on the guest.
  • Installed a fresh copy of Solaris 10u5 (64bit).

Nothing has helped so far.

This issue appears to be triggered by load within the guest itself. For example I had to re-attempt the installation of Sun Communication Suite 5 three times before it would complete without the VM hanging half-way through the process. Installing the same product when the same OS is running in 32bit mode completes without a problem.

I currently have 3 Solaris 10u5 guests running.

#2260 fixed Solaris 10 U5 Host panic Carson Gaspar
Description

I installed vbox 2.0.2 on my Sol 10 x86 U5 server. I created a VM, installed windows server 2008 enterprise, shutdown the VM, attached the addon ISO, started the VM, and my machine panic'd.

I've attached the panic messages from syslog, and the results of 'showrev -p'

I have the core file, let me know what additional information I can provide.

#2261 fixed Windows XP guest freeze Kevin Patterson
Description

Host hardware: MacBook Pro with OS X 10.5.5

Issue: Trying to build a Windows XP SP2 guest and find that it fails after 20% formatting of a dynamic disk. I can reliably reproduce this behaviour every time, even if I try different XP setup media.

Although I've verified the host disk, is this an early indicator that something could be wrong it? I only ask because other work colleagues who have identically-spec'ed MacBook Pros have successfully built XP guests.
