Instead of calling virCgroupForDomain every time we need the virCgrouPtr instance, just do it once at Vm startup and cache a reference to the object in virLXCDomainObjPrivatePtr until shutdown of the VM. Removing the virCgroupPtr from the LXC driver state also means we don't have stale mount info, if someone mounts the cgroups filesystem after libvirtd has been started Signed-off-by: NDaniel P.

The virCgroupMounted method is badly named, since a controller can be mounted, but disabled in the current object. Rename the method to be virCgroupHasController. Also make it tolerant to a NULL virCgroupPtr and out-of-range controller index, to avoid duplication of these checks in all callers Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Currently the LXC container code has two codepaths, depending on whether there is a <filesystem> element with a target path of '/'. If we automatically add a <filesystem> device with src=/ and dst=/, for any container which has not specified a root filesystem, then we only need one codepath for setting up the filesystem.

Some of the LXC callbacks did not lock the virDomainObjPtr instance.

The naming used in the RPC protocols for the LXC monitor and lock daemon confused the script used to generate systemtap helper functions. Rename the LXC monitor protocol symbols to reduce confusion. Adapt the gensystemtap.pl script to cope with the LXC monitor / lock daemon naming conversions. This has no functional impact on RPC wire protocol, since names are only used in the C layer Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

If an LXC domain failed to start because of a bogus SELinux label, virLXCProcessStart would call VIR_CLOSE(0) by mistake. This is because the code which initializes the member of the ttyFDs array to -1 got moved too far away from the place where the array is first allocated. Signed-off-by: NDaniel P.

The virCaps structure gathered a ton of irrelevant data over time that. The original reason is that it was propagated to the XML parser functions. This patch aims to create a new data structure virDomainXMLConf that will contain immutable data that are used by the XML parser. This will allow two things we need: 1) Get rid of the stuff from virCaps 2) Allow us to add callbacks to check and add driver specific stuff after domain XML is parsed. This first attempt removes pointers to private data allocation functions to this new structure and update all callers and function that require them.

Currently we rely on a VIR_ERROR message being logged by the virRaiseError function to report LXC startup errors. This gives the right message, but is rather ugly and can be truncated if lots of log messages are written. Change the LXC controller to explicitly print any virErrorPtr message to stderr. Then change the driver to skip over anything that looks like a log message. The result is that this error: Failed to start domain busy error: internal error guest failed to start: 2013-03-04 19:46:42.846+0000: 1734: info : libvirt version: 1.0.2 2013-03-04 19:46:42.846+0000: 1734: error : virFileLoopDeviceAssociate:600 : Unable to open /root/disk.raw: No such file or directory changes to error: Failed to start domain busy error: internal error guest failed to start: Unable to open /root/disk.raw: No such file or directory Signed-off-by: NDaniel P.

This adds support for host device passthrough with the LXC driver. Since there is only a single kernel image, it doesn't make sense to pass through PCI devices, but USB devices are fine.

Currently to deal with auto-shutdown libvirtd must periodically poll all stateful drivers. Thus sucks because it requires acquiring both the driver lock and locks on every single virtual machine. Instead pass in a "inhibit" callback to virStateInitialize which drivers can invoke whenever they want to inhibit shutdown due to existance of active VMs. Signed-off-by: NDaniel P.

Currently the LXC driver logs audit messages when a container is started or stopped. These audit messages, however, contain the PID of the libvirt_lxc supervisor process. To enable sysadmins to correlate with audit messages generated by processes /inside/ the container, we need to include the container init process PID. We can't do this in the main 'start' audit message, since the init PID is not available at that point. Instead we output a completely new audit record, that lists both PIDs. type=VIRT_CONTROL msg=audit(1353433750.071:363): pid=20180 uid=0 auid=501 ses=3 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 msg='virt=lxc op=init vm="busy" uuid=dda7b947-0846-1759-2873-0f375df7d7eb vm-pid=20371 init-pid=20372 exe="/home/berrange/src/virt/libvirt/daemon/.libs/lt-libvirtd" hostname=? addr=? terminal=pts/6 res=success' Signed-off-by: NDaniel P.

This bug was revealed by the crash described in https://bugzilla.redhat.com/show_bug.cgi?id=852383 The vlan info pointer sent to virNetDevOpenvswitchAddPort should never be non-NULL unless there is at least one tag. The factthat such a vlan info pointer was receveid pointed out that a caller was passing the wrong pointer. Instead of sending &net->vlan, the result of virDomainNetGetActualVlan(net) should be sent - that function will look for vlan info in net->data.network.actual->vlan, and in cany case return NULL instead of a pointer if the vlan info it finds has no tags. Aside from causing the crash, sending a hardcoded &net->vlan has the effect of ignoring vlan info from a <network> or <portgroup> config.
