I tried to test ./configure --without-lxc --without-remote. First, the build failed with some odd errors, such as an inability to build xen, or link failures for virNetTLSInit. But when you think about it, once there is no remote code, all of libvirtd is useless, any stateful driver that depends on libvirtd is also not worth compiling, and any libraries used only by RPC code are not needed. So I patched configure.ac to make for some saner defaults when an explicit disable is attempted. Similarly, since we have migrated virnetdevbridge into generic code, the workaround for Linux kernel stupidity must not depend on stateful drivers being in use. Then there's 'make check' that needs segregation. Wow - quite a bit of cleanup to make --without-remote useful :) * configure.ac: Let --without-remote toggle defaults on stateful drivers and other libraries. Pick up Linux kernel workarounds even when qemu and lxc are not being compiled. * tests/Makefile.am (test_programs): Factor out programs that require remote. * src/libvirt_private.syms (rpc/virnet*.h): Move... * src/libvirt_remote.syms: ...into new file. * src/Makefile.am (SYM_FILES): Ship new syms file.

The problem is described by [0] but its effect on libvirt is that starting a container with a full distro running systemd after having stopped it simply fails. The container cleanup now calls the machined Terminate function to make sure that everything is in order for the next run. [0]: https://bugs.freedesktop.org/show_bug.cgi?id=68370

The functions - iptablesAddForwardDontMasquerade(), - iptablesRemoveForwardDontMasquerade handle exceptions in the masquerading implemented in the POSTROUTING chain of the "nat" table. Such exceptions should be added as chronologically latest, logically top-most rules. The bridge driver will call these functions beginning with the next patch: some special destination IP addresses always refer to the local subnetwork, even though they don't match any practical subnetwork's netmask. Packets from virbrN targeting such IP addresses are never routed outwards, but the current rules treat them as non-virbrN-destined packets and masquerade them. This causes problems for some receivers on virbrN. Signed-off-by: NLaszlo Ersek <lersek@redhat.com>

When using a <interface type="network"> that points to a network with hostdev forwarding mode a hostdev alias is created for the network. This allias is inserted into the hostdev list, but is backed with a part of the network object that it is connected to. When a VM is being stopped qemuProcessStop() calls networkReleaseActualDevice() which eventually frees the memory for the hostdev object. Afterwards when the domain definition is being freed by virDomainDefFree() an invalid pointer is accessed by virDomainHostdevDefFree() and may cause a crash of the daemon. This patch removes the entry in the hostdev list before freeing the depending memory to avoid this issue. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1000973

Since PCI bridges, PCIe bridges, PCIe switches, and PCIe root ports all share the same namespace, they are all defined as controllers of type='pci' in libvirt (but with a differing model attribute). Each of these controllers has a certain connection type upstream, allows certain connection types downstream, and each can either allow a single downstream connection at slot 0, or connections from slot 1 - 31. Right now, we only support the pci-root and pci-bridge devices, both of which only allow PCI devices to connect, and both which have usable slots 1 - 31. In preparation for adding other types of controllers that have different capabilities, this patch 1) adds info to the qemuDomainPCIAddressBus object to indicate the capabilities, 2) sets those capabilities appropriately for pci-root and pci-bridge devices, and 3) validates that the controller being connected to is the proper type when allocating slots or validating that a user-selected slot is appropriate for a device.. Having this infrastructure in place will make it much easier to add support for the other PCI controller types. While it would be possible to do all the necessary checking by just storing the controller model in the qemyuDomainPCIAddressBus, it greatly simplifies all the validation code to also keep a "flags", "minSlot" and "maxSlot" for each - that way we can just check those attributes rather than requiring a nearly identical switch statement everywhere we need to validate compatibility. You may notice many places where the flags are seemingly hard-coded to QEMU_PCI_CONNECT_HOTPLUGGABLE | QEMU_PCI_CONNECT_TYPE_PCI This is currently the correct value for all PCI devices, and in the future will be the default, with small bits of code added to change to the flags for the few devices which are the exceptions to this rule. Finally, there are a few places with "FIXME" comments. Note that these aren't indicating places that are broken according to the currently supported devices, they are places that will need fixing when support for new PCI controller models is added. To assure that there was no regression in the auto-allocation of PCI addresses or auto-creation of integrated pci-root, ide, and usb controllers, a new test case (pci-bridge-many-disks) has been added to both the qemuxml2argv and qemuxml2xml tests. This new test defines a domain with several dozen virtio disks but no pci-root or pci-bridges. The .args file of the new test case was created using libvirt sources from before this patch, and the test still passes after this patch has been applied.

Doing DBus method calls using libdbus.so is tedious in the extreme. systemd developers came up with a nice high level API for DBus method calls (sd_bus_call_method). While systemd doesn't use libdbus.so, their API design can easily be ported to libdbus.so. This patch thus introduces methods virDBusCallMethod & virDBusMessageRead, which are based on the code used for sd_bus_call_method and sd_bus_message_read. This code in systemd is under the LGPLv2+, so we're license compatible. This code is probably pretty unintelligible unless you are familiar with the DBus type system. So I added some API docs trying to explain how to use them, as well as test cases to validate that I didn't screw up the adaptation from the original systemd code. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

These helpers use the remembered host capabilities to retrieve the cpu map rather than query the host again. The intended usage for this helpers is to fix automatic NUMA placement with strict memory alloc. The code doing the prepare needs to pin the emulator process only to cpus belonging to a subset of NUMA nodes of the host.

There are two levels on which a device may be hotplugged: config and live. The config level requires just an insert or remove from internal domain definition structure, which is exactly what this patch does. There is currently no implementation for a chardev update action, as there's not much to be updated. But more importantly, the only thing that can be updated is path or socket address by which chardevs are distinguished. So the update action is currently not supported.
