This is really strongly recommended against. It is better to mount each controller separately at /sys/fs/cgroup/<controller name> and have...

...ere a place in the code I can look where the CPU flags are checked? I did create this VM on the Debian 7 versions of libvirt and qemu, but I don't see that it should be much of a problem since you can swap CPUs in virt-manager. The end goal is to read Sandy Bridge+ RAPL MSRs from the guest OS. perf_events are now being exported, which is great for my work, but if I could read some of those RAPL MSRs, It would make my life orders of magnitude easier. Any help would be much appreciated. Best, Michael Giardino <giardino@ece.gatech.edu> <michael.giardino@gmail.com>
