#6553 obsolete VM freezes when disconnecting USB Sony Ericsson mobile phone AoS
Description

Hello,

Here's my config: Host: Ubunutu 9.10 64 bit Guest: Windows XP

I can connect my mobile phone (Sony Ericsson W995) to my VM to manage the device without any issue. When I disconnect the device (unplug cable), the VM freezes. I tried sending pausing/resuming the VM, replugging the device, sending the shutdown signal but without success.

The only way to get out of this situation is to reset the VM.

Thanks in advance.

#6554 obsolete rdesktop-vrdp segfaults in XPutImage on Debian Squeeze/i386 Maximilian Gass
Description

I created a Debian package for rdesktop-vrdp from VirtualBox 3.1.6. It works fine on a Debian Squeeze amd64 workstation, but segfaults after login on a Debian Squeeze i386 live system I am creating.

I have localized the problem in ui_desktop_restore in xwin.c. The call to XCreateImage returns NULL sometimes and then XPutImage triggers a segmentation fault.

(gdb) bt

#6556 obsolete Ubuntu 9.10 Host/Windows Server 2008 guest - guest intermittent hang Patrick Headley
Description

Host is: Ubuntu 9.10 64-bit Server Kernel = 2.6.33 but older kernels had the same issue Processor = Intel Xeon E5506 times 2 Memory = 23.6GB

Guest1 is: Windows Server 2008 Standard 64-bit SP2 Memory = 6GB but I've gone as low as 2GB Processor Cores = 3 with VT-x enabled but the number of cores don't seem to matter Video Memory = 128GB with 2D and 3D Acceleration enabled

Guest2 is: Windows Small Business Server 2008 64-bit SP2 Memory = 8GB Processor Cores = 3 with VT-x enabled but the number of cores don't seem to matter Video Memory = 128GB with 2D and 3D Acceleration enabled

The problem is that either guest will intermittently hang. Guest1 is more prone to hanging than Guest2. Guest2 has only hung-up a couple times since January of 2010. Guest1 may hang while booting or it could run for a week or more. It will typically hang-up every two or three days. Sometimes after rebooting the host the issue gets considerably worse or considerably better but there is no way I know of to reproduce one or the other.

The work-around that I've come up with is to stop the VirtualBox Guest Additions Service after booting the guest and logging in. I have not tried setting the service to disabled or to start manually.

I have a 10-year old Pentium-4 (32-bit) server with 2 processors with Ubuntu 9.10 as the host OS and one Windows XP (32-bit) guest. That machine has not experienced this issue.
