When adding devices to the definition it's useful to check whether the devices don't reside on a conflicting address. This patch adds a helper that iterates all device info and compares the addresses with the given info.

Some code paths have special logic depending on the page size reported by sysconf, which in turn affects the test results. We must mock this so tests always have a consistent page size.

Do the allocation first, then add the actual device. The second part should never fail. This is good for live hotplug where we don't want to remove the device on OOM after the monitor command succeeded. The only change in behavior is that on failure, the vmdef->consoles array is freed, not just the first console.

For stateless, client side drivers, it is never correct to probe for secondary drivers. It is only ever appropriate to use the secondary driver that is associated with the hypervisor in question. As a result the ESX & HyperV drivers have both been forced to do hacks where they register no-op drivers for the ones they don't implement. For stateful, server side drivers, we always just want to use the same built-in shared driver. The exception is virtualbox which is really a stateless driver and so wants to use its own server side secondary drivers. To deal with this virtualbox has to be built as 3 separate loadable modules to allow registration to work in the right order. This can all be simplified by introducing a new struct recording the precise set of secondary drivers each hypervisor driver wants struct _virConnectDriver { virHypervisorDriverPtr hypervisorDriver; virInterfaceDriverPtr interfaceDriver; virNetworkDriverPtr networkDriver; virNodeDeviceDriverPtr nodeDeviceDriver; virNWFilterDriverPtr nwfilterDriver; virSecretDriverPtr secretDriver; virStorageDriverPtr storageDriver; }; Instead of registering the hypervisor driver, we now just register a virConnectDriver instead. This allows us to remove all probing of secondary drivers. Once we have chosen the primary driver, we immediately know the correct secondary drivers to use. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

A bunch of code is wrapped in #if WITH_LIBVIRTD in order to enable the virStateDriver to be disabled when libvirtd is not built. Disabling this code doesn't have any real functional benefit beyond removing 1 pointer from the virConnectPtr struct, while having a cost of many more conditionals. Signed-off-by: NDaniel P.

Add a virDBusErrorIsUnknownMethod helper so that callers don't need todo string comparisons themselves to detect standard error names.
-
由 Daniel P. Berrange 提交于
The virDBusMethodCall method has a DBusError as one of its parameters. If the caller wants to pass a non-NULL value for this, it immediately makes the calling code require DBus at build time. This has led to breakage of non-DBus builds several times. It is desirable that only the virdbus.c file should need WITH_DBUS conditionals, so we must ideally remove the DBusError parameter from the method. We can't simply raise a libvirt error, since the whole point of this parameter is to give the callers a way to check if the error is one they want to ignore, without having the logs polluted with an error message. So, we add a virErrorPtr parameter which the caller can then either ignore or raise using the new virReportErrorObject method. This new method is distinct from virSetError in that it ensures the logging hooks are run. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

The virDomainDefParse* and virDomainDefFormat* methods both accept the VIR_DOMAIN_XML_* flags defined in the public API, along with a set of other VIR_DOMAIN_XML_INTERNAL_* flags defined in domain_conf.c. This is seriously confusing & error prone for a number of reasons: - VIR_DOMAIN_XML_SECURE, VIR_DOMAIN_XML_MIGRATABLE and VIR_DOMAIN_XML_UPDATE_CPU are only relevant for the formatting operation - Some of the VIR_DOMAIN_XML_INTERNAL_* flags only apply to parse or to format, but not both. This patch cleanly separates out the flags. There are two distint VIR_DOMAIN_DEF_PARSE_* and VIR_DOMAIN_DEF_FORMAT_* flags that are used by the corresponding methods. The VIR_DOMAIN_XML_* flags received via public API calls must be converted to the VIR_DOMAIN_DEF_FORMAT_* flags where needed. The various calls to virDomainDefParse which hardcoded the use of the VIR_DOMAIN_XML_INACTIVE flag change to use the VIR_DOMAIN_DEF_PARSE_INACTIVE flag.

Currently, when there is an API that's blocking with locked domain and second API that's waiting in virDomainObjListFindByUUID() for the domain lock (with the domain list locked) no other API can be executed on any domain on the whole hypervisor because all would wait for the domain list to be locked. This patch adds new optional approach to this in which the domain is only ref'd (reference counter is incremented) instead of being locked and is locked *after* the list itself is unlocked. We might consider only ref'ing the domain in the future and leaving locking on particular APIs, but that's no tonight's fairy tale. Signed-off-by: NMartin Kletzander <mkletzan@redhat.com>

At the time that the network driver allocates a connection to a network, the tap device that will be used hasn't yet been created - that will be done later by qemu (or lxc or whoever) - but if the network has macTableManager='libvirt', then when we do get around to creating the tap device, we will need to add an entry for it to the network bridge's fdb (forwarding database) *and* turn off learning and unicast_flood for that tap device in the bridge's sysfs settings. This means that qemu needs to know both the bridge name as well as the setting of macTableManager, so we either need to create a new API to retrieve that info, or just pass it back in the ActualNetDef that is created during networkAllocateActualDevice. We choose the latter method, since it's already done for the bridge device, and it has the side effect of making the information available in domain status. (NB: in the future, I think that the tap device should actually be created by networkAllocateActualDevice(), as that will solve several other problems, but that is a battle for another day, and this information will still be useful outside the network driver)

The macTableManager attribute of a network's bridge subelement tells libvirt how the bridge's MAC address table (used to determine the egress port for packets) is managed. In the default mode, "kernel", management is left to the kernel, which usually determines entries in part by turning on promiscuous mode on all ports of the bridge, flooding packets to all ports when the correct destination is unknown, and adding/removing entries to the fdb as it sees incoming traffic from particular MAC addresses. In "libvirt" mode, libvirt turns off learning and flooding on all the bridge ports connected to guest domain interfaces, and adds/removes entries according to the MAC addresses in the domain interface configurations. A side effect of turning off learning and unicast_flood on the ports of a bridge is that (with Linux kernel 3.17 and newer), the kernel can automatically turn off promiscuous mode on one or more of the bridge's ports (usually only the one interface that is used to connect the bridge to the physical network). The result is better performance (because packets aren't being flooded to all ports, and can be dropped earlier when they are of no interest) and slightly better security (a guest can still send out packets with a spoofed source MAC address, but will only receive traffic intended for the guest interface's configured MAC address). The attribute looks like this in the configuration: <network> <name>test</name> <bridge name='br0' macTableManager='libvirt'/> ... This patch only adds the config knob, documentation, and test cases. The functionality behind this knob is added in later patches.

These two functions use netlink RTM_NEWNEIGH and RTM_DELNEIGH messages to add and delete entries from a bridge's fdb. The bridge itself is not referenced in the arguments to the functions, only the name of the device that is attached to the bridge (since a device can only be attached to one bridge at a time, and must be attached for this function to make sense, the kernel easily infers which bridge's fdb is being modified by looking at the device name/index).
