Also even when setting the profile to aa-complain I see: [14406.210381] audit: type=1400 audit(1491482071.335:67): apparmor="ALLOWED" operation="setrlimit" profile="/usr/sbin/libvirtd" pid=7674 comm="libvirtd" rlimit=memlock value=2164260864
So far so good, but still the value is not raised. As if the action never happened. So on an ALLOWED setrlimit to pid 7674 the value afterwards is not the value set in the call.

Thanks to jjohansen we debugged some of it and eventually I was asked to report to a bug. Symptom: [ 8976.950635] audit: type=1400 audit(1491310016.224:48): apparmor="DENIED" operation="setrlimit" profile="/usr/sbin/libvirtd" pid=10034 comm="libvirtd" rlimit=memlock value=1610612736 But none of the profiles has any rlimit statement in it: $ grep -Hirn limit /etc/apparmor* /etc/apparmor.d/sbin.dhclient:58: # such, if the dhclient3 daemon is subverted, this effectively limits it to /etc/apparmor.d/abstractions/ubuntu-helpers:16:# Limitations: /etc/apparmor.d/abstractions/ubuntu-helpers:64: # in limited libraries so glibc's secure execution should be enough to not /etc/apparmor.d/cache/.features:13:rlimit {mask {cpu fsize data stack core rss nproc nofile memlock as locks sigpending msgqueue nice rtprio rttime The profile contains a child profile which makes reading the dumps a bit painful, but I'll attach them anyway for you to take a look.
