Package: xen-utils-common
Version: 4.11.3+24-g14b62ab3e5-1
Severity: important
Hello,
In case memory in dom0 gets tight, the OOM killer tends to try to kill
xenstored and xenconsoled. From then on it's very difficult to control
the VMs running on the system... It'd be good to protect them from the
OOM since they are so precious.
I'm currently using a hack such as
for i in $(pgrep xenconsoled) ; do
echo -1000 > /proc/$i/oom_score_adj
done
in /etc/init.d/xen, but there are cleaner ways to do this :)
