#10543 obsolete VERR_VMM_RING0_ASSERTION (VMMRZCallRing3: enmOperation=9) E1
Description

I have an intermittent fault with an Ubuntu 10.04 host with a windows SRV2003 Guest in terminal services mode. VBox is 4.1.6 r74727 . 16Gb RAM on Host. This Guest is the only one running on this host and the host does nothing else but run this server.

Every now and again I get a halt error and switch to Guru_Meditation, exact fault is:

Guru Meditation -2701 (VERR_VMM_RING0_ASSERTION)

Have tried reducing RAM assigned to guest to 3500 from 3584, and enabling PAE in guest

#10548 obsolete CentOS Guest - Mini Toolbar not visible in full screen mode w/ 3D enabled + compiz \
Description

The VB mini toolbar is not be visible when running in a Linux (CentOS 6.2 guest) with compiz installed and 3D acceleration enabled w/ guest additions. This only occurs when running the guest OS in the same full screen resolution of the host.

As Tested: VirtualBox: 4.1.14 r77440 Host: Windows 7 (6.1.7601 SP1 Build 7601) Guest: CentOS 6.2 (Kernel 2.6.32-220.13.1el6.x86_64) Compiz 0.8.2

Steps to reproduce:

  • Configure all of the above as tested and ensure compiz is running.
  • Set guest to full screen and either auto-resize guest to native resolution of host or manually configure guest to use native resolution.

Observe: minitoolbar will not be visible when running in full screen.

WORKAROUND:

  • Set the mini toolbar to be visible at the bottom of the screen
  • Configure the vertical resolution of the guest OS to be at least 1 pixel less than the native resolution of the host. To accomplish this, I set

my guest resolution to "1920x1079" from "1920x1080" in /etc/X11/xorg.conf.

  • Restart linux window manager or reboot the guest, go to display setting and your custom resolution should appear as an option to select.
#10550 obsolete VM crashes when connecting via VNC jackwhaines
Description

I have a fresh install of 4.1.14_OSE on a FreeBSD 9.0 server. Dual Quad-Core 3.33Ghz w/ 32GB RAM. I have 3 other boxes with similar hardware running great, although running on 4.1.12_OSE. Moved 2 VMs from those servers to the new server and then created a new VM on the new server. Everything works great until I attempt to VNC to the port. When I do, it connects, but never shows screen. After 15-20 seconds, the VM crashes and I get a Bus error: 10 (core dumped)
