I've tried to reproduce the issue but failed miserably. I installed a fresh Ubuntu 18.04.1 made a cqow image essentially copying the filesystem for the guest. That means I was running the 4.15.0-29-generic kernel (reported as affected) both as host and guest. After an hour of running with 50
hogs (as root) I hit OOM but not the reported bug:

# uname -r
4.15.0-29-generic
# ~/git/stress-ng/stress-ng --sysfs 50 -t 5h
stress-ng: info: [1148] dispatching hogs: 50 sysfs

Can you provide some more information about your setup (e.g. qemu version, domain xml or qemu command line, etc.)?
