      numad: Always output 'placement' of <vcpu> · d70f2e11
      Osier Yang 提交于
      <vcpu> is not an optional node. The value for its 'placement'
      actually always defaults to 'static' in the underlying codes.
      (Even no 'cpuset' and 'placement' is specified, the domain
      process will be pinned to all the available pCPUs).

      numad: Set memory policy from numad advisory nodeset · 97010eb1
      Osier Yang 提交于
      Though numad will manage the memory allocation of task dynamically,
      it wants management application (libvirt) to pre-set the memory
      policy according to the advisory nodeset returned from querying numad,
      (just like pre-bind CPU nodeset for domain process), and thus the
      performance could benefit much more from it.
      
      This patch introduces new XML tag 'placement', value 'auto' indicates
      whether to set the memory policy with the advisory nodeset from numad,
      and its value defaults to the value of <vcpu> placement, or 'static'
      if 'nodeset' is specified. Example of the new XML tag's usage:
      
        <numatune>
          <memory placement='auto' mode='interleave'/>
        </numatune>
      
      Just like what current "numatune" does, the 'auto' numa memory policy
      setting uses libnuma's API too.
      
      If <vcpu> "placement" is "auto", and <numatune> is not specified
      explicitly, a default <numatume> will be added with "placement"
      set as "auto", and "mode" set as "strict".
      
      The following XML can now fully drive numad:
      
      1) <vcpu> placement is 'auto', no <numatune> is specified.
      
         <vcpu placement='auto'>10</vcpu>
      
      2) <vcpu> placement is 'auto', no 'placement' is specified for
         <numatune>.
      
         <vcpu placement='auto'>10</vcpu>
         <numatune>
           <memory mode='interleave'/>
         </numatune>
      
      And it's also able to control the CPU placement and memory policy
      independently. e.g.
      
      1) <vcpu> placement is 'auto', and <numatune> placement is 'static'
      
         <vcpu placement='auto'>10</vcpu>
         <numatune>
           <memory mode='strict' nodeset='0-10,^7'/>
         </numatune>
      
      2) <vcpu> placement is 'static', and <numatune> placement is 'auto'
      
         <vcpu placement='static' cpuset='0-24,^12'>10</vcpu>
         <numatune>
           <memory mode='interleave' placement='auto'/>
         </numatume>
      
      A follow up patch will change the XML formatting codes to always output
      'placement' for <vcpu>, even it's 'static'.

      blockjob: enhance xml to track mirrors across libvirtd restart · ae6aa8c3
      Eric Blake 提交于
      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.

      Since Xen 3.1 the clock=variable semantic is supported. In addition to

      qemu: Support numad · 0f8e7ae3
      Osier Yang 提交于
      numad is an user-level daemon that monitors NUMA topology and
      processes resource consumption to facilitate good NUMA resource
      alignment of applications/virtual machines to improve performance
      and minimize cost of remote memory latencies. It provides a
      pre-placement advisory interface, so significant processes can
      be pre-bound to nodes with sufficient available resources.
      
      More details: http://fedoraproject.org/wiki/Features/numad
      
      "numad -w ncpus:memory_amount" is the advisory interface numad
      provides currently.
      
      This patch add the support by introducing a new XML attribute
      for <vcpu>. e.g.
      
        <vcpu placement="auto">4</vcpu>
        <vcpu placement="static" cpuset="1-10^6">4</vcpu>
      
      The returned advisory nodeset from numad will be printed
      in domain's dumped XML. e.g.
        <vcpu placement="auto" cpuset="1-10^6">4</vcpu>
      
      If placement is "auto", the number of vcpus and the current
      memory amount specified in domain XML will be used for numad
      command line (numad uses MB for memory amount):
        numad -w $num_of_vcpus:$current_memory_amount / 1024
      
      The advisory nodeset returned from numad will be used to set
      domain process CPU affinity then. (e.g. qemuProcessInitCpuAffinity).
      
      If the user specifies both CPU affinity policy (e.g.
      (<vcpu cpuset="1-10,^7,^8">4</vcpu>) and placement == "auto"
      the specified CPU affinity will be overridden.
      
      Only QEMU/KVM drivers support it now.
      
      See docs update in patch for more details.

      Make it obvious to 'dumpxml' readers what unit we are using,
      since our default of KiB for memory (1024) differs from qemu's
      default of MiB; and differs from our use of bytes for storage.
      
      Tests were updated via:
      
      $ find tests/*data tests/*out -name '*.xml' | \

      followed by a few fixes for the stragglers.
      
      Note that with this patch, the RNG for <memory> still forbids
      validation of anything except unit='KiB', since the code silently
      ignores the attribute; a later patch will expand <memory> to allow
      scaled input in the code and update the RNG to match.

      qemu: support type='hostdev' network devices at domain start · 8639a420
      Laine Stump 提交于
      This patch makes sure that each network device ("interface") of
      type='hostdev' appears on both the hostdevs list and the nets list of
      the virDomainDef, and it modifies the qemu driver startup code so that
      these devices will be presented to qemu on the commandline as hostdevs
      rather than as network devices.
      
      It does not add support for hotplug of these type of devices, or code
      to honor the <mac address> or <virtualport> given in the config (both
      of those will be done in separate patches).
      
      Once each device is placed on both lists, much of what this patch does
      is modify places in the code that traverse all the device lists so
      that these hybrid devices are only acted on once - either along with
      the other hostdevs, or along with the other network interfaces. (In
      many cases, only one of the lists is traversed / a specific operation
      is performed on only one type of device. In those instances, the code
      can remain unchanged.)
      
      There is one special case - when building the commandline, interfaces
      are allowed to proceed all the way through
      networkAllocateActualDevice() before deciding to skip the rest of
      netdev-specific processing - this is so that (once we have support for
      networks with pools of hostdev devices) we can get the actual device
      allocated, then rely on the loop processing all hostdevs to generate
      the correct commandline.
      
      (NB: <interface type='hostdev'> is only supported for PCI network
      devices that are SR-IOV Virtual Functions (VF). Standard PCI[e] and
      USB devices, and even the Physical Functions (PF) of SR-IOV devices
      can only be assigned to a guest using the more basic <hostdev> device
      entry. This limitation is mostly due to the fact that non-SR-IOV
      ethernet devices tend to lose mac address configuration whenever the
      card is reset, which happens when a card is assigned to a guest;
      SR-IOV VFs fortunately don't suffer the same problem.)

      conf: parse/format type='hostdev' network interfaces · 3b1c191f
      Laine Stump 提交于
      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).

      Osier Yang 提交于
      For any disk controller model which is not "lsilogic", the command
      line will be like:
      
        -drive file=/dev/sda,if=none,id=drive-scsi0-0-3-0,format=raw \
        -device scsi-disk,bus=scsi0.0,channel=0,scsi-id=3,lun=0,i\
        drive=drive-scsi0-0-3-0,id=scsi0-0-3-0
      
      The relationship between the libvirt address attrs and the qdev
      properties are (controller model is not "lsilogic"; strings
      inside <> represent libvirt adress attrs):
        bus=scsi<controller>.0
        channel=<bus>
        scsi-id=<target>
        lun=<unit>

        for function qemuBuildDriveDevStr; new param "virDomainDefPtr
        vmdef" for function qemuAssignDeviceDiskAlias. Both for
        virDomainDiskFindControllerModel's use).
      
      * src/qemu/qemu_command.c:
        - New param "virDomainDefPtr def" for qemuAssignDeviceDiskAliasCustom.
          For virDomainDiskFindControllerModel's use, if the disk bus is "scsi"
          and the controller model is not "lsilogic", "target" is one part of
          the alias name.
        - According change on qemuAssignDeviceDiskAlias and qemuBuildDriveDevStr
      
      * src/qemu/qemu_hotplug.c:

      domain: add implicit USB controller · 42043afc
      Marc-André Lureau 提交于
      Some tools, such as virt-manager, prefers having the default USB
      controller explicit in the XML document. This patch makes sure there
      is one. With this patch, it is now possible to switch from USB1 to
      USB2 from the release 0.9.1 of virt-manager.
      
      Fix tests to pass with this change.

      seclabel: Do not output relabel attribute for type 'none' · f6957617
      Jiri Denemark 提交于
      Security label type 'none' requires relabel to be set to 'no' so there's
      no reason to output this extra attribute.  Moreover, since relabel is
      internally stored in a negative from (norelabel), the default value for
      relabel would be 'yes' in case there is no <seclabel> element in domain
      configuration.  In case VIR_DOMAIN_SECLABEL_DEFAULT turns into
      VIR_DOMAIN_SECLABEL_NONE, we would incorrectly output relabel='yes' for
      seclabel type 'none'.

      seclabel: make code and RNG match · c052d8a8

      Commit b170eb99 introduced a bug: domains that had an explicit
      <seclabel type='none'/> when started would not be reparsed if
      libvirtd restarted.  It turns out that our testsuite was not
      exercising this because it never tried anything but inactive
      parsing.  Additionally, the live XML for such a domain failed
      to re-validate.  Applying just the tests/ portion of this patch
      will expose the bugs that are fixed by the other two files.
      
      * docs/schemas/domaincommon.rng (seclabel): Allow relabel under
      type='none'.
      * src/conf/domain_conf.c (virSecurityLabelDefParseXML): Per RNG,
      presence of <seclabel> with no type implies dynamic.  Don't
      require sub-elements for type='none'.
      * tests/qemuxml2xmltest.c (mymain): Add test.
      * tests/qemuxml2argvtest.c (mymain): Likewise.

      conf: add rawio attribute to disk element of domain XML · 397e6a70
      Taku Izumi 提交于
       This patch adds a new attribute "rawio" to the "disk" element
       of domain XML. Valid values of "rawio" attribute are "yes"
       and "no".
       rawio='yes' indicates the disk is desirous of CAP_SYS_RAWIO.
      
       If you specify the following XML:
      
       <disk type='block' device='lun' rawio='yes'>
        ...
       </disk>
      
       the domain will be granted CAP_SYS_RAWIO.
       (of course, the domain have to be executed with root privilege)
      
      NOTE:
         - "rawio" attribute is only valid when device='lun'
         - At the moment, any other disks you won't use rawio can use rawio.

      qemu: add "romfile" support to specify device boot ROM · 3801831c
      Laine Stump 提交于
      This patch addresses: https://bugzilla.redhat.com/show_bug.cgi?id=781562
      
      Along with the "rombar" option that controls whether or not a boot rom
      is made visible to the guest, qemu also has a "romfile" option that
      allows specifying a binary file to present as the ROM BIOS of any
      emulated or passthrough PCI device. This patch adds support for
      specifying romfile to both passthrough PCI devices, and emulated
      network devices that attach to the guest's PCI bus (just about
      everything other than ne2k_isa).
      
      One example of the usefulness of this option is described in the
      bugzilla report: 82576 sriov network adapters don't provide a ROM BIOS
      for the cards virtual functions (VF), but an image of such a ROM is
      available, and with this ROM visible to the guest, it can PXE boot.
      
      In libvirt's xml, the new option is configured like this:
      
         <hostdev>
           ...
           <rom file='/etc/fake/boot.bin'/>
           ...
         </hostdev
      
      (similarly for <interface>).

      qemu: (and conf) support rombar for network devices · 3284ac04
      Laine Stump 提交于
      When support for the rombar option was added, it was only added for
      PCI passthrough devices, configured with <hostdev>. The same option is
      available for any network device that is attached to the guest's PCI
      bus. This patch allows setting rombar for any PCI network device type.
      
      After adding cases to test this to qemuxml2argv-hostdev-pci-rombar.*,
      I decided to rename those files (to qemuxml2argv-pci-rom.*) to more
      accurately reflect the additional tests, and also noticed that up to
      now we've only been performing a domainschematest for that case, so I
      added the "pci-rom" test to both qemuxml2argv and qemuxml2xml (and in
      the process found some bugs whose fixes I squashed into previous
      commits of this series).

      conf: relocate rombar and boot order parse/format · c01ba1a4
      Laine Stump 提交于
      Since these two items are now in the virDomainDeviceInfo struct, it
      makes sense to parse/format them in the functions written to
      parse/format that structure. Not all types of devices allow them, so
      two internal flags are added to indicate when it is appropriate to do
      so.
      
      I was lucky - only one test case needed to be re-ordered!

      qemu: parse and create -cpu ...,-kvmclock · b66d1bef
      Paolo Bonzini 提交于
      QEMU supports a bunch of CPUID features that are tied to the kvm CPUID
      nodes rather than the processor's.  They are "kvmclock",
      "kvm_nopiodelay", "kvm_mmu", "kvm_asyncpf".  These are not known to
      libvirt and their CPUID leaf might move if (for example) the Hyper-V
      extensions are enabled. Hence their handling would anyway require some
      special-casing.
      
      However, among these the most useful is kvmclock; an additional
      "property" of this feature is that a <timer> element is a better model
      than a CPUID feature.  Although, creating part of the -cpu command-line
      from something other than the <cpu> XML element introduces some
      ugliness.

      Add new attribute wrpolicy to <driver> element · d9e0d820
      Deepak C Shetty 提交于
      This introduces new attribute wrpolicy with only supported
      value as immediate. This will be an optional
      attribute with no defaults. This helps specify whether
      to skip the host page cache.
      
      When wrpolicy is specified, meaning when wrpolicy=immediate
      a writeback is explicitly initiated for the dirty pages in
      the host page cache as part of the guest file write operation.
      
      Usage:
      <filesystem type='mount' accessmode='passthrough'>
        <driver type='path' wrpolicy='immediate'/>
        <source dir='/export/to/guest'/>
        <target dir='mount_tag'/>
      </filesystem>
      
      Currently this only works with type='mount' for the QEMU/KVM driver.
