In XML format, by definition, order of fields should not matter, so order of parsing the elements doesn't affect the end result. When specifying guest NUMA cells, we depend only on the order of the 'cell' elements. With this patch all older domain XMLs are parsed as before, but with the 'id' attribute they are parsed and formatted according to that field. This will be useful when we have tuning settings for particular guest NUMA node. Signed-off-by: NMartin Kletzander <mkletzan@redhat.com>

This patch adds support for the QEMU vhost-user feature to libvirt. vhost-user enables the communication between a QEMU virtual machine and other userspace process using the Virtio transport protocol. It uses a char dev (e.g. Unix socket) for the control plane, while the data plane based on shared memory. The XML looks like: <interface type='vhostuser'> <mac address='52:54:00:3b:83:1a'/> <source type='unix' path='/tmp/vhost.sock' mode='server'/> <model type='virtio'/> </interface> Signed-off-by: NMichele Paolino <m.paolino@virtualopensystems.com> Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

Add 'nocow' to storage volume xml so that user can have an option to set NOCOW flag to the newly created volume. It's useful on btrfs file system to enhance performance. Btrfs has low performance when hosting VM images, even more when the guest in those VM are also using btrfs as file system. One way to mitigate this bad performance is to turn off COW attributes on VM files. Generally, there are two ways to turn off COW on btrfs: a) by mounting fs with nodatacow, then all newly created files will be NOCOW. b) per file. Add the NOCOW file attribute. It could only be done to empty or new files. This patch tries the second way, according to 'nocow' option, it could set NOCOW flag per file: for raw file images, handle 'nocow' in libvirt code; for non-raw file images, pass 'nocow=on' option to qemu-img, and let qemu-img to handle that (requires qemu-img version >= 2.1).

This new module holds and formats capabilities for emulator. If you are about to create a new domain, you may want to know what is the host or hypervisor capable of. To make sure we don't regress on the XML, the formatting is not something left for each driver to implement, rather there's general format function. The domain capabilities is a lockable object (even though the locking is not necessary yet) which uses reference counter. Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

Check if the buffer is in error state and report an error if it is. This replaces the pattern: if (virBufferError(buf)) { virReportOOMError(); goto cleanup; } with: if (virBufferCheckError(buf) < 0) goto cleanup; Document typical buffer usage to favor this. Also remove the redundant FreeAndReset - if an error has been set via virBufferSetError, the content is already freed.

We publish libvirt-api.xml for others to use, and in fact, the libvirt-python bindings use it to generate python constants that correspond to our enum values. However, we had an off-by-one bug that any enum that relied on C's rules for implicit initialization of the first enum member to 0 got listed in the xml as having a value of 1 (and all later members of the enum were equally botched). The fix is simple - since we add one to the previous value when encountering an enum without an initializer, the previous value must start at -1 so that the first enum member is assigned 0. The python generator code has had the off-by-one ever since DV first wrote it years ago, but most of our public enums were immune because they had an explicit = 0 initializer. The only affected enums are: - virDomainEventGraphicsAddressType (such as VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV4), since commit 987e31ed (libvirt v0.8.0) - virDomainCoreDumpFormat (such as VIR_DOMAIN_CORE_DUMP_FORMAT_RAW), since commit 9fbaff00 (libvirt v1.2.3) - virIPAddrType (such as VIR_IP_ADDR_TYPE_IPV4), since commit 03e0e79e (not yet released) Thanks to Nehal J Wani for reporting the problem on IRC, and for helping me zero in on the culprit function. * docs/apibuild.py (CParser.parseEnumBlock): Fix implicit enum values.

The interface state for bonds and vlans does seem to reflect the state of the underlying physical devices, at least in some cases, so it makes sense to allow reporting it (netcf now does). The link state/speed for bridge devices is meaningless though, so we don't even look for it.

The interface xml schema was written with strict rules about the ordering of the elements. This was never intentional, but just due to omission of <interleave> in the appropriate places. This patch just adds in <interleave> wherever there is more than one element, and re-indents everything else appropriately.

There are two places where you'll find info on page sizes. The first one is under <cpu/> element, where all supported pages sizes are listed. Then the second one is under each <cell/> element which refers to concrete NUMA node. At this place, the size of page's pool is reported.

Commit 7c6fc394 introduced a regression in the XML produced for older clients. The argument at the time was that clients shouldn't be depending on output-only data for something that is only going to be triggered for a transient guest; but John Ferlan reported that the automated testsuite was such a client. It's better to be safe than sorry by guaranteeing back-compat cruft. Note that later patches will be using <mirror> for active block commit, but there we don't have to worry about back-compat. * src/conf/domain_conf.c (virDomainDiskDefFormat): Restore old style output when necessary. * docs/schemas/domaincommon.rng: Validate back-compat style. * docs/formatdomain.html.in: Update the documentation. * tests/qemuxml2xmloutdata/qemuxml2xmlout-disk-mirror-old.xml: Update tests. * tests/qemuxml2argvdata/qemuxml2argv-disk-mirror.xml: Likewise.

While exposing the info under <interface/> in previous patch works, it may work only in cases where interface is configured on the host. However, orchestrating application may want to know the link state and speed even in that case. That's why we ought to expose this in nodedev XML too: virsh # nodedev-dumpxml net_eth0_f0_de_f1_2b_1b_f3 <device> <name>net_eth0_f0_de_f1_2b_1b_f3</name> <path>/sys/devices/pci0000:00/0000:00:19.0/net/eth0</path> <parent>pci_0000_00_19_0</parent> <capability type='net'> <interface>eth0</interface> <address>f0:de:f1:2b:1b:f3</address> <link speed='1000' state='up'/> <capability type='80203'/> </capability> </device> Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

Currently it is not possible to determine the speed of an interface and whether a link is actually detected from the API. Orchestrating platforms want to be able to determine when the link has failed and where multiple speeds may be available which one the interface is actually connected at. This commit introduces an extension to our interface XML (without implementation to interface driver backends): <interface type='ethernet' name='eth0'> <start mode='none'/> <mac address='aa:bb:cc:dd:ee:ff'/> <link speed='1000' state='up'/> <mtu size='1492'/> ... </interface> Where @speed is negotiated link speed in Mbits per second, and state is the current NIC state (can be one of the following: "unknown", "notpresent", "down", "lowerlayerdown","testing", "dormant", "up").

Now that we track a disk mirror as a virStorageSource, we might as well update the XML to theoretically allow any type of mirroring destination (not just a local file). A later patch will also be reusing <mirror> to track the block commit of the top layer of a chain, which is another case where libvirt needs to update the backing chain after the job is finally pivoted, and since backing chains can have network backing files as the destination to commit into, it makes more sense to display that in the XML. This patch changes output-only XML; it was already documented that <mirror> does not affect a domain definition at this point (because qemu doesn't provide persistent bitmaps yet). Any application that was starting a block copy job with older libvirt and then relying on the domain XML to determine if it was complete will no longer be able to access the file= and format= attributes of mirror that were previously used. However, this is not going to be a problem in practice: the only time a block copy job works is on a transient domain, and any app that is managing a transient domain probably already does enough of its own bookkeeping to know which file it is mirroring into without having to re-read it from the libvirt XML. The one thing that was likely to be used in a mirroring job was the ready= attribute, which is unchanged. Meanwhile, I made sure the schema and parser still accept the old format, even if we no longer output it, so that upgrading from an older version of libvirt is seamless. * docs/schemas/domaincommon.rng (diskMirror): Alter definition. * src/conf/domain_conf.c (virDomainDiskDefParseXML): Parse two styles of mirror elements. (virDomainDiskDefFormat): Output new style. * tests/qemuxml2argvdata/qemuxml2argv-disk-mirror-old.xml: New file, copied from... * tests/qemuxml2argvdata/qemuxml2argv-disk-mirror.xml: ...here before modernizing. * tests/qemuxml2xmloutdata/qemuxml2xmlout-disk-mirror-old*: New files. * tests/qemuxml2xmltest.c (mymain): Test both styles.

A PCI device can be associated with a specific NUMA node. Later, when a guest is pinned to one NUMA node the PCI device can be assigned on different NUMA node. This makes DMA transfers travel across nodes and thus results in suboptimal performance. We should expose the NUMA node locality for PCI devices so management applications can make better decisions.

If user or management application wants to create a guest, it may be useful to know the cost of internode latencies before the guest resources are pinned. For example: <capabilities> <host> ... <topology> <cells num='2'> <cell id='0'> <memory unit='KiB'>4004132</memory> <distances> <sibling id='0' value='10'/> <sibling id='1' value='20'/> </distances> <cpus num='2'> <cpu id='0' socket_id='0' core_id='0' siblings='0'/> <cpu id='2' socket_id='0' core_id='2' siblings='2'/> </cpus> </cell> <cell id='1'> <memory unit='KiB'>4030064</memory> <distances> <sibling id='0' value='20'/> <sibling id='1' value='10'/> </distances> <cpus num='2'> <cpu id='1' socket_id='0' core_id='0' siblings='1'/> <cpu id='3' socket_id='0' core_id='2' siblings='3'/> </cpus> </cell> </cells> </topology> ... </host> ... </capabilities> We can see the distance from node1 to node0 is 20 and within nodes 10.

Our documentation generator is a bit messy, to say the least. For instance, the description to return values of a function is searched within C comment. Currently, all lines that start with 'returns' or 'Returns' are viewed as return value description. However, there are some valid uses where the 'returns' word is in the middle of a sentence describing function behavior not the return value. And there are no places where 'returns' is used to describe return values. For instance: virDomainDetachDeviceFlags, virConnectNetworkEventRegisterAny and virDomainGetDiskErrors. This leads to HTML documemtation being generated incorrectly. Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>
