Bug Description
What happened:
libvirt console.log consumed >100GB of disk on a single vm, DoSing the compute node.
What you expected to happen:
libvirt should be using virtlogd which supports rotation and has sane defaults, and this wouldn't happen, as this was fixed upstream.
How to reproduce it:
Boot a vm, run anything in the serial console which outputs infinitely, wait until compute node crashes.
yes > /dev/stdout
or from any root shell, write infinitely to kmesg/printk.
