Create on the host side a new freezer cgroup, put UML into it and freeze/thaw it. i.e. mkdir /sys/fs/cgroup/freezer/uml ; echo <pid of a shell> > /sys/fs/cgroup/freezer/uml/tasks. In the said shell run UML and then freeze it using echo FROZEN > /sys/fs/cgroup/freezer/uml/freezer.state. Later thaw it: echo THAWED > /sys/fs/cgroup/freezer/uml/freezer.state Thanks, //richard -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
