So here's a weird bug.

I have an F19 (minimal) guest on an F19 host. With the default qxl/spice config, if I do something like (at a VT - minimal install, remember):

less /var/log/messages
cat /var/log/messages
less /var/log/audit/audit.log
cat /var/log/audit/audit.log

really anything that causes a bunch of text to get printed to the screen, the system will print some of the text then crash (in the 'less' case, it usually crashes after I page down once or twice).

This happens whether I use virt-manager or spicec as the console. It does *not* happen if I use the 'vga' video adapter instead of 'qxl' - either with VNC or with SPICE. It *does* still happen if I pass 'nomodeset' with the qxl/spice config, though.

The screen freezes for a few seconds, then the VM shuts down.

It looks like I get an abrt crash report for qemu. abrt reporting is busted with F19 at present, so I'll attach the files from the abrt directory manually.

If you want to try and reproduce, to get a working F19 install, you can do an F18 install, do 'yum --releasever=19 --nogpgcheck distro-sync', then edit /etc/grub2.cfg and replace all occurrences of "Schrodingers Cat" with "Schrodingers Cat". That works at time of going to press.
