Since qemu 2.9 via 9103f1ce "file-posix: Consider max_segments for BlockLimits.max_transfer" this is a new access that is denied by the qemu profile. It is non fatal, but prevents the fix mentioned to actually work. It should be safe to allow reading from that path. Since qemu opens a symlink path we need to translate that for apparmor from "/sys/dev/block/*/queue/max_segments" to "/sys/devices/**/block/*/queue/max_segments" Signed-off-by: Christian Ehrhardt <christian.ehrhardt@canonical.com>
