Disclaimer: I don't have any experience prior to today on cgroups.
I've been looking into getting openvz containers to work on the (unsupported) debian 3.10 kernel and *think* I'm close. I've been getting an error about "Failed to set limits for CPU limits (Cgroup, requested group parameter does not exist)". I used strace on starting the vm and found this:
I have an idea that this the missing cpu.cfs_quota_us may possibly be required (see Ref 1 below). What I don't understand is why this would be needed if the vm's "CPULIMIT" is 0. Is it possible to recompile my kernel with support for "cfs_quota_us"?
