seclabel: extend XML to allow per-disk label overrides When doing security relabeling, there are cases where a per-file override might be appropriate. For example, with a static label and relabeling, it might be appropriate to skip relabeling on a particular disk, where the backing file lives on NFS that lacks the ability to track labeling. Or with dynamic labeling, it might be appropriate to use a custom (non-dynamic) label for a disk specifically intended to be shared across domains. The new XML resembles the top-level <seclabel>, but with fewer options (basically relabel='no', or <label>text</label>): <domain ...> ... <devices> <disk type='file' device='disk'> <source file='/path/to/image1'> <seclabel relabel='no'/> <!-- override for just this disk --> </source> ... </disk> <disk type='file' device='disk'> <source file='/path/to/image1'> <seclabel relabel='yes'> <!-- override for just this disk --> <label>system_u:object_r:shared_content_t:s0</label> </seclabel> </source> ... </disk> ... </devices> <seclabel type='dynamic' model='selinux'> <baselabel>text</baselabel> <!-- used for all devices without override --> </seclabel> </domain> This patch only introduces the XML and documentation; future patches will actually parse and make use of it. The intent is that we can further extend things as needed, adding a per-device <seclabel> in more places (such as the source of a console device), and possibly allowing a <baselabel> instead of <label> for labeling where we want to reuse the cNNN,cNNN pair of a dynamically labeled domain but a different base label. First suggested by Daniel P. Berrange here: https://www.redhat.com/archives/libvir-list/2011-December/msg00258.html * docs/schemas/domaincommon.rng (devSeclabel): New define.

selinux: distinguish failure to label from request to avoid label https://bugzilla.redhat.com/show_bug.cgi?id=924153 Commit 904e05a2 (v0.9.9) added a per-<disk> seclabel element with an attribute relabel='no' in order to try and minimize the impact of shutdown delays when an NFS server disappears. The idea was that if a disk is on NFS and can't be labeled in the first place, there is no need to attempt the (no-op) relabel on domain shutdown. Unfortunately, the way this was implemented was by modifying the domain XML so that the optimization would survive libvirtd restart, but in a way that is indistinguishable from an explicit user setting. Furthermore, once the setting is turned on, libvirt avoids attempts at labeling, even for operations like snapshot or blockcopy where the chain is being extended or pivoted onto non-NFS, where SELinux labeling is once again possible. As a result, it was impossible to do a blockcopy to pivot from an NFS image file onto a local file. The solution is to separate the semantics of a chain that must not be labeled (which the user can set even on persistent domains) vs. the optimization of not attempting a relabel on cleanup (a live-only annotation), and using only the user's explicit notation rather than the optimization as the decision on whether to skip a label attempt in the first place. When upgrading an older libvirtd to a newer, an NFS volume will still attempt the relabel; but as the avoidance of a relabel was only an optimization, this shouldn't cause any problems. In the ideal future, libvirt will eventually have XML describing EVERY file in the backing chain, with each file having a separate <seclabel> element. At that point, libvirt will be able to track more closely which files need a relabel attempt at shutdown. But until we reach that point, the single <seclabel> for the entire <disk> chain is treated as a hint - when a chain has only one file, then we know it is accurate; but if the chain has more than one file, we have to attempt relabel in spite of the attribute, in case part of the chain is local and SELinux mattered for that portion of the chain. * src/conf/domain_conf.h (_virSecurityDeviceLabelDef): Add new member. * src/conf/domain_conf.c (virSecurityDeviceLabelDefParseXML): Parse it, for live images only.

blockjob: enhance xml to track mirrors across libvirtd restart In order to track a block copy job across libvirtd restarts, we need to save internal XML that tracks the name of the file holding the mirror. Displaying this name in dumpxml might also be useful to the user, even if we don't yet have a way to (re-) start a domain with mirroring enabled up front. This is done with a new <mirror> sub-element to <disk>, as in: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/original.img'/> <mirror file='/var/lib/libvirt/images/copy.img' format='qcow2' ready='yes'/> ... </disk> For now, the element is output-only, in live domains; it is ignored when defining a domain or hot-plugging a disk (since those contexts use VIR_DOMAIN_XML_INACTIVE in parsing). The 'ready' attribute appears when libvirt knows that the job has changed from the initial pulling phase over to the mirroring phase, although absence of the attribute is not a sure indicator of the current phase. If we come up with a way to make qemu start with mirroring enabled, we can relax the xml restriction, and allow <mirror> (but not attribute 'ready') on input. Testing active-only XML meant tweaking the testsuite slightly, but it was worth it. * docs/schemas/domaincommon.rng (diskspec): Add diskMirror. * docs/formatdomain.html.in (elementsDisks): Document it. * src/conf/domain_conf.h (_virDomainDiskDef): New members. * src/conf/domain_conf.c (virDomainDiskDefFree): Clean them. (virDomainDiskDefParseXML): Parse them, but only internally. (virDomainDiskDefFormat): Output them. * tests/qemuxml2argvdata/qemuxml2argv-disk-mirror.xml: New test file. * tests/qemuxml2xmloutdata/qemuxml2xmlout-disk-mirror.xml: Likewise. * tests/qemuxml2xmltest.c (testInfo): Alter members. (testCompareXMLToXMLHelper): Allow more test control. (mymain): Run new test.

conf: set up for per-grammar overrides in schemas This patch is my first experience playing with nested grammars, as documented in http://relaxng.org/tutorial-20011203.html#IDA3PZR. I plan on doing more overrides in order to make the RelaxNG grammar mirror the C code refactoring into a common virStorageSource, but where different clients of that source do not support the same subset of functionality. By starting with something fairly easy to validate, I can make sure my later patches will be possible. This patch adds a use of the no-op <ref name='sourceStartupPolicy'/> to the disksnapshot definition, so that the snapshot version of a type='file' <source> more closely resembles the version in domaincommon. A future patch will merge the two files into using a common define, but this patch is sufficient for testing that adding <source startupPolicy='optional'/> in any of the tests/domainsnapshotxml2xmlin/*.xml files still gets rejected unless it occurs within the <domain> subelement, because the definition of startupPolicy is empty outside of domain.rng. * docs/schemas/storagecommon.rng (storageStartupPolicy) (storageSourceExtra): Create no-op defaults. * docs/schemas/domainsnapshot.rng (domain): Use nested grammar to avoid restricting <domain>. (storageSourceExtra): Create new override. (disksnapshot): Access overrides through common names. * docs/schemas/domaincommon.rng (disk): Access overrides through common names. * docs/schemas/domain.rng (storageStartupPolicy) (storageSourceExtra): Create new overrides.

snapshot: also support disks by path I got confused when 'virsh domblkinfo dom disk' required the path to a disk (which can be ambiguous, since a single file can back multiple disks), rather than the unambiguous target device name that I was using in disk snapshots.

blockjob: enhance xml to track mirrors across libvirtd restart In order to track a block copy job across libvirtd restarts, we need to save internal XML that tracks the name of the file holding the mirror. Displaying this name in dumpxml might also be useful to the user, even if we don't yet have a way to (re-) start a domain with mirroring enabled up front. This is done with a new <mirror> sub-element to <disk>, as in: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/original.img'/> <mirror file='/var/lib/libvirt/images/copy.img' format='qcow2' ready='yes'/> ... </disk> For now, the element is output-only, in live domains; it is ignored when defining a domain or hot-plugging a disk (since those contexts use VIR_DOMAIN_XML_INACTIVE in parsing). The 'ready' attribute appears when libvirt knows that the job has changed from the initial pulling phase over to the mirroring phase, although absence of the attribute is not a sure indicator of the current phase. If we come up with a way to make qemu start with mirroring enabled, we can relax the xml restriction, and allow <mirror> (but not attribute 'ready') on input. Testing active-only XML meant tweaking the testsuite slightly, but it was worth it. * docs/schemas/domaincommon.rng (diskspec): Add diskMirror. * docs/formatdomain.html.in (elementsDisks): Document it. * src/conf/domain_conf.h (_virDomainDiskDef): New members. * src/conf/domain_conf.c (virDomainDiskDefFree): Clean them. (virDomainDiskDefParseXML): Parse them, but only internally. (virDomainDiskDefFormat): Output them. * tests/qemuxml2argvdata/qemuxml2argv-disk-mirror.xml: New test file. * tests/qemuxml2xmloutdata/qemuxml2xmlout-disk-mirror.xml: Likewise. * tests/qemuxml2xmltest.c (testInfo): Alter members. (testCompareXMLToXMLHelper): Allow more test control. (mymain): Run new test.

conf: add new <model> subelement with name attribute to <controller> This new subelement is used in PCI controllers: the toplevel *attribute* "model" of a controller denotes what kind of PCI controller is being described, e.g. a "dmi-to-pci-bridge", "pci-bridge", or "pci-root". But in the future there will be different implementations of some of those types of PCI controllers, which behave similarly from libvirt's point of view (and so should have the same model), but use a different device in qemu (and present themselves as a different piece of hardware in the guest). In an ideal world we (i.e. "I") would have thought of that back when the pci controllers were added, and used some sort of type/class/model notation (where class was used in the way we are now using model, and model was used for the actual manufacturer's model number of a particular family of PCI controller), but that opportunity is long past, so as an alternative, this patch allows selecting a particular implementation of a pci controller with the "name" attribute of the <model> subelement, e.g.: <controller type='pci' model='dmi-to-pci-bridge' index='1'> <model name='i82801b11-bridge'/> </controller> In this case, "dmi-to-pci-bridge" is the kind of controller (one that has a single PCIe port upstream, and 32 standard PCI ports downstream, which are not hotpluggable), and the qemu device to be used to implement this kind of controller is named "i82801b11-bridge". Implementing the above now will allow us in the future to add a new kind of dmi-to-pci-bridge that doesn't use qemu's i82801b11-bridge device, but instead uses something else (which doesn't yet exist, but qemu people have been discussing it), all without breaking existing configs. (note that for the existing "pci-bridge" type of PCI controller, both the model attribute and <model> name are 'pci-bridge'. This is just a coincidence, since it turns out that in this case the device name in qemu really is a generic 'pci-bridge' rather than being the name of some real-world chip)

conf: add new <target> subelement with chassisNr attribute to <controller> There are some configuration options to some types of pci controllers that are currently automatically derived from other parts of the controller's configuration. For example, in qemu a pci-bridge controller has an option that is called "chassis_nr"; up until now libvirt has always set chassis_nr to the index of the pci-bridge. So this: <controller type='pci' model='pci-bridge' index='2'/> will always result in: -device pci-bridge,chassis_nr=2,... on the qemu commandline. In the future we may decide there is a better way to derive that option, but even in that case we will need for existing domains to retain the same chassis_nr they were using in the past - that is something that is visible to the guest so it is part of the guest ABI and changing it would lead to problems for migrating guests (or just guests with very picky OSes). The <target> subelement has been added as a place to put the new "chassisNr" attribute that will be filled in by libvirt when it auto-generates the chassisNr; it will be saved in the config, then reused any time the domain is started: <controller type='pci' model='pci-bridge' index='2'> <model type='pci-bridge'/> <target chassisNr='2'/> </controller> The one oddity of all this is that if the controller configuration is changed (for example to change the index or the pci address where the controller is plugged in), the items in <target> will *not* be re-generated, which might lead to conflict. I can't really see any way around this, but fortunately if there is a material conflict qemu will let us know and we will pass that on to the user.

conf: support host-side IP/route information in <interface> This is place as a sub-element of <source>, where other aspects of the host-side connection to the network device are located (network or bridge name, udp listen port, etc). It's a bit odd that the interface we're configuring with this info is itself named in <target dev='x'/>, but that ship sailed long ago: <interface type='ethernet'> <mac address='00:16:3e:0f:ef:8a'/> <source> <ip address='192.168.122.12' family='ipv4' prefix='24' peer='192.168.122.1'/> <ip address='192.168.122.13' family='ipv4' prefix='24'/> <route family='ipv4' address='0.0.0.0' gateway='192.168.122.1'/> <route family='ipv4' address='192.168.124.0' prefix='24' gateway='192.168.124.1'/> </source> </interface> In practice, this will likely only be useful for type='ethernet', so its presence in any other type of interface is currently forbidden in the generic device Validate function (but it's been put into the general population of virDomainNetDef rather than the ethernet-specific union member so that 1) we can more easily add the capability to other types if needed, and 2) we can retain the info when set to an invalid interface type all the way through to validation and report a proper error, rather than just ignoring it (which is currently what happens for many other type-specific settings). (NB: The already-existing configuration of IP info for the guest-side of interfaces is in subelements directly under <interface>, and the name of the guest-side interface (when configurable) is in <guest dev='x'/>). (This patch had been pushed earlier in commit fe6a77898a38f491403a70cc49925a584101daee, but was reverted in commit d658456530c1010a49f45865613ed361a0fcc5b4 because it had been accidentally pushed during the freeze for release 2.0.0)

conf: parse/format type='hostdev' network interfaces This is the new interface type that sets up an SR-IOV PCI network device to be assigned to the guest with PCI passthrough after initializing some network device-specific things from the config (e.g. MAC address, virtualport profile parameters). Here is an example of the syntax: <interface type='hostdev' managed='yes'> <source> <address type='pci' domain='0' bus='0' slot='4' function='3'/> </source> <mac address='00:11:22:33:44:55'/> <address type='pci' domain='0' bus='0' slot='7' function='0'/> </interface> This would assign the PCI card from bus 0 slot 4 function 3 on the host, to bus 0 slot 7 function 0 on the guest, but would first set the MAC address of the card to 00:11:22:33:44:55. NB: The parser and formatter don't care if the PCI card being specified is a standard single function network adapter, or a virtual function (VF) of an SR-IOV capable network adapter, but the upcoming code that implements the back end of this config will work *only* with SR-IOV VFs. This is because modifying the mac address of a standard network adapter prior to assigning it to a guest is pointless - part of the device reset that occurs during that process will reset the MAC address to the value programmed into the card's firmware. Although it's not supported by any of libvirt's hypervisor drivers, usb network hostdevs are also supported in the parser and formatter for completeness and consistency. <source> syntax is identical to that for plain <hostdev> devices, except that the <address> element should have "type='usb'" added if bus/device are specified: <interface type='hostdev'> <source> <address type='usb' bus='0' device='4'/> </source> <mac address='00:11:22:33:44:55'/> </interface> If the vendor/product form of usb specification is used, type='usb' is implied: <interface type='hostdev'> <source> <vendor id='0x0012'/> <product id='0x24dd'/> </source> <mac address='00:11:22:33:44:55'/> </interface> Again, the upcoming patch to fill in the backend of this functionality will log an error and fail with "Unsupported Config" if you actually try to assign a USB network adapter to a guest using <interface type='hostdev'> - just use a standard <hostdev> entry in that case (and also for single-port PCI adapters).

conf: add <vlan> element to network and domain interface elements The following config elements now support a <vlan> subelements: within a domain: <interface>, and the <actual> subelement of <interface> within a network: the toplevel, as well as any <portgroup> Each vlan element must have one or more <tag id='n'/> subelements. If there is more than one tag, it is assumed that vlan trunking is being requested. If trunking is required with only a single tag, the attribute "trunk='yes'" should be added to the toplevel <vlan> element. Some examples: <interface type='hostdev'/> <vlan> <tag id='42'/> </vlan> <mac address='52:54:00:12:34:56'/> ... </interface> <network> <name>vlan-net</name> <vlan trunk='yes'> <tag id='30'/> </vlan> <virtualport type='openvswitch'/> </network> <interface type='network'/> <source network='vlan-net'/> ... </interface> <network> <name>trunk-vlan</name> <vlan> <tag id='42'/> <tag id='43'/> </vlan> ... </network> <network> <name>multi</name> ... <portgroup name='production'/> <vlan> <tag id='42'/> </vlan> </portgroup> <portgroup name='test'/> <vlan> <tag id='666'/> </vlan> </portgroup> </network> <interface type='network'/> <source network='multi' portgroup='test'/> ... </interface> IMPORTANT NOTE: As of this patch there is no backend support for the vlan element for *any* network device type. When support is added in later patches, it will only be for those select network types that support setting up a vlan on the host side, without the guest's involvement. (For example, it will be possible to configure a vlan for a guest connected to an openvswitch bridge, but it won't be possible to do that for one that is connected to a standard Linux host bridge.)

docs: Fix XML schema handling of LUN address in hostdev tag Defining a domain with a SCSI disk attached via a hostdev tag and a source address unit value longer than two digits causes an error when editing the domain with virsh edit, even if no changes are made to the domain definition. The error suggests invalid XML, somewhere: # virsh edit lmb_guest error: XML document failed to validate against schema: Unable to validate doc against /usr/local/share/libvirt/schemas/domain.rng Extra element devices in interleave Element domain failed to validate content The virt-xml-validate tool fails with a similar error: # virt-xml-validate lmb_guest.xml Relax-NG validity error : Extra element devices in interleave lmb_guest.xml:17: element devices: Relax-NG validity error : Element domain failed to validate content lmb_guest.xml fails to validate The hostdev tag requires a source address to be specified, which includes bus, target, and unit address attributes. According to the SCSI Architecture Model spec (section 4.9 of SAM-2), a LUN address is 64 bits and thus could be up to 20 decimal digits long. Unfortunately, the XML schema limits this string to just two digits. Similarly, the target field can be up to 32 bits in length, which would be 10 decimal digits. # lsscsi -xx [0:0:19:0x4022401100000000] disk IBM 2107900 3.44 /dev/sda # lsscsi [0:0:19:1074872354]disk IBM 2107900 3.44 /dev/sda # cat lmb_guest.xml <domain type='kvm'> <name>lmb_guest</name> <memory unit='MiB'>1024</memory> ...trimmed... <devices> <controller type='scsi' model='virtio-scsi' index='0'/> <hostdev mode='subsystem' type='scsi'> <source> <adapter name='scsi_host0'/> <address bus='0' target='19' unit='1074872354'/> </source> </hostdev> ...trimmed... Since the reference unit and target fields are used in several places in the XML schema, create a separate one specific for SCSI Logical Units that will permit the greater length. This permits both the validation utility and the virsh edit command to succeed when a hostdev tag is included.

conf: alter disk mirror xml output 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.

blockjob: enhance xml to track mirrors across libvirtd restart In order to track a block copy job across libvirtd restarts, we need to save internal XML that tracks the name of the file holding the mirror. Displaying this name in dumpxml might also be useful to the user, even if we don't yet have a way to (re-) start a domain with mirroring enabled up front. This is done with a new <mirror> sub-element to <disk>, as in: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/original.img'/> <mirror file='/var/lib/libvirt/images/copy.img' format='qcow2' ready='yes'/> ... </disk> For now, the element is output-only, in live domains; it is ignored when defining a domain or hot-plugging a disk (since those contexts use VIR_DOMAIN_XML_INACTIVE in parsing). The 'ready' attribute appears when libvirt knows that the job has changed from the initial pulling phase over to the mirroring phase, although absence of the attribute is not a sure indicator of the current phase. If we come up with a way to make qemu start with mirroring enabled, we can relax the xml restriction, and allow <mirror> (but not attribute 'ready') on input. Testing active-only XML meant tweaking the testsuite slightly, but it was worth it. * docs/schemas/domaincommon.rng (diskspec): Add diskMirror. * docs/formatdomain.html.in (elementsDisks): Document it. * src/conf/domain_conf.h (_virDomainDiskDef): New members. * src/conf/domain_conf.c (virDomainDiskDefFree): Clean them.

blockcommit: track job type in xml A future patch is going to wire up qemu active block commit jobs; but as they have similar events and are canceled/pivoted in the same way as block copy jobs, it is easiest to track all bookkeeping for the commit job by reusing the <mirror> element. This patch adds domain XML to track which job was responsible for creating a mirroring situation, and adds a job='copy' attribute to all existing uses of <mirror>. Along the way, it also massages the qemu monitor backend to read the new field in order to generate the correct type of libvirt job (even though it requires a future patch to actually cause a qemu event that can be reported as an active commit).

blockcopy: add more XML for state tracking Doing a blockcopy operation across a libvirtd restart is not very robust at the moment. In particular, we are clearing the <mirror> element prior to telling qemu to finish the job. Also, thanks to the ability to request async completion, the user can easily regain control prior to qemu actually finishing the effort, and they should be able to poll the domain XML to see if the job is still going. A future patch will fix things to actually wait until qemu is done before modifying the XML to reflect the job completion. But since qemu issues identical BLOCK_JOB_COMPLETE events regardless of whether the job was cancelled (kept the original disk) or completed (pivoted to the new disk), we have to track which of the two operations were used to end the job. Furthermore, we'd like to avoid attempts to end a job where we are already waiting on an earlier request to qemu to end the job. Likewise, if we miss the qemu event (perhaps because it arrived during a libvirtd restart), we still need enough state recorded to be able to determine how to modify the domain XML once we reconnect to qemu and manually learn whether the job still exists. Although this patch doesn't actually fix the problem, it is a preliminary step that makes it possible to track whether a job has already begun steps towards completion. * src/conf/domain_conf.h (virDomainDiskMirrorState): New enum.

docs: Fix XML schema handling of LUN address in hostdev tag Defining a domain with a SCSI disk attached via a hostdev tag and a source address unit value longer than two digits causes an error when editing the domain with virsh edit, even if no changes are made to the domain definition. The error suggests invalid XML, somewhere: # virsh edit lmb_guest error: XML document failed to validate against schema: Unable to validate doc against /usr/local/share/libvirt/schemas/domain.rng Extra element devices in interleave Element domain failed to validate content The virt-xml-validate tool fails with a similar error: # virt-xml-validate lmb_guest.xml Relax-NG validity error : Extra element devices in interleave lmb_guest.xml:17: element devices: Relax-NG validity error : Element domain failed to validate content lmb_guest.xml fails to validate The hostdev tag requires a source address to be specified, which includes bus, target, and unit address attributes. According to the SCSI Architecture Model spec (section 4.9 of SAM-2), a LUN address is 64 bits and thus could be up to 20 decimal digits long. Unfortunately, the XML schema limits this string to just two digits. Similarly, the target field can be up to 32 bits in length, which would be 10 decimal digits. # lsscsi -xx [0:0:19:0x4022401100000000] disk IBM 2107900 3.44 /dev/sda # lsscsi [0:0:19:1074872354]disk IBM 2107900 3.44 /dev/sda # cat lmb_guest.xml <domain type='kvm'> <name>lmb_guest</name> <memory unit='MiB'>1024</memory> ...trimmed... <devices> <controller type='scsi' model='virtio-scsi' index='0'/> <hostdev mode='subsystem' type='scsi'> <source> <adapter name='scsi_host0'/> <address bus='0' target='19' unit='1074872354'/> </source> </hostdev> ...trimmed... Since the reference unit and target fields are used in several places in the XML schema, create a separate one specific for SCSI Logical Units that will permit the greater length. This permits both the validation utility and the virsh edit command to succeed when a hostdev tag is included.
