Leveraging from the original bug this came from when debugging: As a workaround for the case reported a user might set memtune options for the guest like this: <memtune> <hard_limit unit='KiB'>16961536</hard_limit> <soft_limit unit='KiB'>16961536</soft_limit> </memtune>
Needed numbers may vary depending on the case. Ugly but a workaround at least. This is still really awkward, at least we need to understand why it is even blocking when it should not. If there is no fix that makes it "just work" I'm fine SRUing something into the libvirt/qemu profiles but we'd need to know what and so far we don't. ** Changed in: apparmor (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apparmor in Ubuntu. https://bugs.launchpad.net/bugs/1679704 Title: libvirt profile is blocking global setrlimit despite having no rlimit rule Status in apparmor package in Ubuntu: New Bug description: Hi, while debugging bug 1678322 I was running along apparmor issues. 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.
