Hello,
I'm testing cgroups on an Ubuntu 10.04 machine and have run into some
difficulty trying to contain a named process. In /etc/cgrules.conf I have
user1:emacs memory user1/emacs/
user2 memory user2/
and in /etc/cgconfig.conf I have
mount {
cpu = /mnt/cgroups/cpu;
cpuacct = /mnt/cgroups/cpuacct;
memory = /mnt/cgroups/memory;
}
group user1/emacs {
perm {
task {
uid = user1;
}
admin {
uid = root;
}
}
memory {
memory.limit_in_bytes = 10485760;
}
}
group user2 {
perm {
admin {
uid = root;
}
task {
uid = root;
}
}
memory {
memory.limit_in_bytes = 1048576;
}
}
If I run "cgexec -g memory:user1/emacs emacs" as user user1, the process
process shows up in /mnt/cgroups/memory/user1/emacs/tasks. If I just run
emacs as user1, the process does not show up there. If user1/emacs task
uid is set to root, I cannot successfully cgexec.
cgrulesengd is running and I also have the cgroup PAM module loaded via
the common-session stack. All of user2's jobs show up in
/mnt/cgroups/memory/user2/tasks without requiring cgexec.
Any advice on how to configure named processes would be greatly
appreciated.
Thanks,
Ryan
