#20944 invalid VM icons blurry in VirtualBox Manager after upgrade from 6.1.30 to 6.1.34 BrentS
Description

The icons for my virtual machines were crisp and in color under VirtualBox 6.1.30 (and previous versions). I just upgraded to 6.1.34 and they now appear in grayscale and blurry (screenshot attached).

Running under x86_654 Slackware Linux 15.0, Xorg 1.20.14, KDE 5.24.5, NVidia proprietary display driver 510.60.02, not using Wayland, 32-bit color depth and normal suite of X11 extensions, no graphical issues with other applications. I did not log out of my X session or adjust any other settings between exiting from 6.1.30, running the installer and extension pack installer (via VBoxManage), and starting 6.1.34 and immediately seeing the problem. xdpyinfo output also attached.

#15969 duplicate VirtualBox 5.1.x Error for Windows 7 Guest: VERR_IEM_INSTR_NOT_IMPLEMENTED BrettR
Description

Windows 7 Guest was crashing on Mac OS X El Capitan 10.11.6 Host for VirtualBox versions 5.1.4 and 5.1.6. I tried installing a fresh copy of Windows 7 on both VirtualBox 5.1.x versions mentioned but would still experience VirtualBox fatal errors. Discovered these errors would occur when taxing the Windows 7 guest, particularly when using the Windows Update tool.

I've tested VirtualBox 5.1.4/5.1.6 with a variety of settings, with subsequent fresh installs of Windows 7, but I experience these fatal errors no matter what.

I rolled back to VirtualBox 4.3.40 to try and reproduce the VERR_IEM_INSTR_NOT_IMPLEMENTED fatal errors -- so far I've had no such issues. It would appear this bug stems from some addition to the 5.0 or 5.1 updates.

#11944 obsolete Virtualbox "Error opening file for reading: Permission denied" when run from command line Brian B
Description

When the virtualbox command is run from the command line I get the following error:

Error opening file for reading: Permission denied

Eventually I used strace to track this down:

[pid 16866] open("/proc/self/auxv", O_RDONLY) = -1 EACCES (Permission denied)
Error opening file for reading: Permission denied

Examining it, that file is owned by root but I'm running virtualbox as a non-privileged user. I'm guessing it gets created early and then virtualbox drops privileges before opening the file:

# ls -l /proc/16866/auxv
-r-------- 1 root root 0 Jul  8 16:55 /proc/16866/auxv
