Hi Should libvirtd be in a cgroup hierarchy rooted at /dev/cgroup or it can be rooted also at /cgroup i,e can /etc/cgconfig.conf look like his (without the /dev) : mount { cpuset = /cgroup/cpuset; cpu = /cgroup/cpu; cpuacct = /cgroup/cpuacct; memory = /cgroup/memory; devices = /cgroup/devices; freezer = /cgroup/freezer; net_cls = /cgroup/net_cls; ns = /cgroup/ns; blkio = /cgroup/blkio; } thanks Zvi Dubitzky Email:dubi@il.ibm.com
