systemd-machined introduced a new method CreateMachineWithNetwork that obsoletes CreateMachine. It expects to be given a list of VETH/TAP device indexes for the host side device(s) associated with a container/machine. This falls back to the old CreateMachine method when the new one is not supported.

If we don't properly clean up all processes in the machine-<vmname>.scope systemd won't remove the cgroup and subsequent vm starts fail with 'CreateMachine: File exists' Additional processes can e.g. be added via echo $PID > /sys/fs/cgroup/systemd/machine.slice/machine-${VMNAME}.scope/tasks but there are other cases like http://bugs.debian.org/761521 Invoke TerminateMachine to be on the safe side since systemd tracks the cgroup anyway. This is a noop if all processes have terminated already.

Added <capabilities> in the <features> section of LXC domains configuration. This section can contain elements named after the capabilities like: <mknod state="on"/>, keep CAP_MKNOD capability <sys_chroot state="off"/> drop CAP_SYS_CHROOT capability Users can restrict or give more capabilities than the default using this mechanism.

Cgroups code uses VIR_CGROUP_DEVICE_* flags to specify the mode but in the end it needs to be converted to a string. Add a helper to do it and use it in the cgroup code before introducing it into the rest of the code.

Currently, virCgroupGetPercpuStats is only used by the LXC driver, filling out the CPUTIME stats. qemuDomainGetPercpuStats does this and also filles out VCPUTIME stats. Extend virCgroupGetPercpuStats to also report VCPUTIME stats if nvcpupids is non-zero. In the LXC driver, we don't have cpupids. In the QEMU driver, there is at least one cpupid for a running domain, so the behavior shouldn't change for QEMU either. Also rename getSumVcpuPercpuStats to virCgroupGetPercpuVcpuSum.

Make future patches smaller by matching a sane header listing in the first place. No semantic change. * src/util/vircgroup.h: Move free next to new, and controller functions next to each other. * src/util/vircgroup.c (virCgroupFree, virCgroupHasController) (virCgroupPathOfController, virCgroupRemoveRecursively) (virCgroupRemove): Sort implementation to be closer to header.

Systemd uses a named cgroup mount for tracking processes. Add it as another type of controller, albeit one which we have to special case in a number of places. In particular we must never create/delete directories there, nor add tasks. Essentially the systemd mount is to be considered read-only for libvirt. With this change both the virCgroupDetectPlacement and virCgroupCopyPlacement methods must be invoked. The copy placement method will copy setup for resource controllers only. The detect placement method will probe for any named controllers, or resource controllers not already setup. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Currently when getting an instance of virCgroupPtr we will create the path in all cgroup controllers. Only at the virt driver layer are we attempting to filter controllers. This is bad because the mere act of creating the dirs in the controllers can have a functional impact on the kernel, particularly for performance. Update the virCgroupForDriver() method to accept a bitmask of controllers to use. Only create dirs in the controllers that are requested. When creating cgroups for domains, respect the active controller list from the parent cgroup Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>
