[lxc-users] memory.limit_in_bytes works, but not memory.memsw.limit_in_bytes and cpuset.cpus

Hi.

I setup some containers (lxc 1.1.2 ubuntu-lxc-git-stable-1_1 ppa) and i 
can configure memory with memory.limit_in_bytes, but i have two 
problems:

- if i try to setup the swap memory limit with 
memory.memsw.limit_in_bytes (in config or with lxc-cgroup), don't work 
aparently, this is a minor problem now, the servers works only with 
real memory, swap is only for minimal use in general.

- if i setup the cpus with cpuset.cpus and the cores are consecutive 
(lxc-cgroup -n $container cpuset.cpus 2,3) this appear inside the 
container (/proc/cpuinfo show two cores) but, if are non-cosecutive 
(lxc-cgroup -n $container cpuset.cpus 2,6) then in /proc/cpuinfo only 
appear one core (with top/htop too) but if i do:

stress -c 8 --timeout 5s

in the container, outside in the host (with htop for example) that 
correctly the cores 2 and 6 are stressed. The failure is cosmetic, but 
in the container only will report one cpu.
