Suddenly I got this "guru meditation" error and I have no clue on what could cause it. These machines - real and virtual - were not in true use, they were idle most of time.

Host system:

NAME="openSUSE Leap"
VERSION="15.0"
ID="opensuse-leap"
ID_LIKE="suse opensuse"
VERSION_ID="15.0"
PRETTY_NAME="openSUSE Leap 15.0"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:leap:15.0"


Virtual machine:

Ubuntu 18.04 LTS (I think most important informations are in the log). If more is needed, I can try to send it when asked.

Thanks!

That is not an official build of VirtualBox. You should try one of the official builds from the download page, remember to update the extension pack and Guest Additions as well, then let us know if you still have problems.
