      Remove 'brControl' object · 6cfeb9a7
      Daniel P. Berrange 提交于
      The bridge management APIs in src/util/bridge.c require a brControl
      object to be passed around. This holds the file descriptor for the
      control socket. This extra object complicates use of the API for
      only a minor efficiency gain, which is in turn entirely offset by
      the need to fork/exec the brctl command for STP configuration.
      
      This patch removes the 'brControl' object entirely, instead opening
      the control socket & closing it again within the scope of each method.
      
      The parameter names for the APIs are also made to consistently use
      'brname' for bridge device name, and 'ifname' for an interface
      device name. Finally annotations are added for non-NULL parameters
      and return check validation
      
      * src/util/bridge.c, src/util/bridge.h: Remove brControl object
        and update API parameter names & annotations.

      Sometimes it is useful to be able to automatically destroy a guest when
      a connection is closed. For example, kill an incoming migration if
      the client managing the migration dies. This introduces a map between

      Integrate the QEMU driver with the lock manager infrastructure · 12317957
      Daniel P. Berrange 提交于
      The QEMU integrates with the lock manager instructure in a number
      of key places
      
       * During startup, a lock is acquired in between the fork & exec
       * During startup, the libvirtd process acquires a lock before
         setting file labelling
       * During shutdown, the libvirtd process acquires a lock
         before restoring file labelling
       * During hotplug, unplug & media change the libvirtd process
         holds a lock while setting/restoring labels
      
      The main content lock is only ever held by the QEMU child process,
      or libvirtd during VM shutdown. The rest of the operations only
      require libvirtd to hold the metadata locks, relying on the active
      QEMU still holding the content lock.

      Refactor the security drivers to simplify usage · d6623003
      Daniel P. Berrange 提交于
      The current security driver usage requires horrible code like
      
          if (driver->securityDriver &&
              driver->securityDriver->domainSetSecurityHostdevLabel &&
              driver->securityDriver->domainSetSecurityHostdevLabel(driver->securityDriver,
                                                                    vm, hostdev) < 0)
      
      This pair of checks for NULL clutters up the code, making the driver
      calls 2 lines longer than they really need to be. The goal of the
      patchset is to change the calling convention to simply
      
        if (virSecurityManagerSetHostdevLabel(driver->securityDriver,
                                              vm, hostdev) < 0)
      
      The first check for 'driver->securityDriver' being NULL is removed
      by introducing a 'no op' security driver that will always be present
      if no real driver is enabled. This guarentees driver->securityDriver
      != NULL.
      
      The second check for 'driver->securityDriver->domainSetSecurityHostdevLabel'
      being non-NULL is hidden in a new abstraction called virSecurityManager.
      This separates the driver callbacks, from main internal API. The addition
      of a virSecurityManager object, that is separate from the virSecurityDriver
      struct also allows for security drivers to carry state / configuration
      information directly. Thus the DAC/Stack drivers from src/qemu which
      used to pull config from 'struct qemud_driver' can now be moved into
      the 'src/security' directory and store their config directly.

      802.1Qbg: use pre-associate state at beginning of inc. migr · c2b38277
      Stefan Berger 提交于
      This patch introduces the usage of the pre-associate state of the IEEE 802.1Qbg standard on incoming VM migration on the target host. It is in response to bugzilla entry 632750.
      
      https://bugzilla.redhat.com/show_bug.cgi?id=632750
      
      For being able to differentiate the exact reason as to why a macvtap device is being created, either due to a VM creation or an incoming VM migration, I needed to pass that reason as a parameter from wherever qemudStartVMDaemon is being called in order to determine whether to send an ASSOCIATE (VM creation) or a PRE-ASSOCIATE (incoming VM migration) towards lldpad.
      
      I am also fixing a problem with the virsh domainxml-to-native call on the way.
      
      Gerhard successfully tested the patch with a recent blade network 802.1Qbg-compliant switch.
      
      The patch should not have any side-effects on the 802.1Qbh support in libvirt, but Roopa (cc'ed) may want to verify this.

      KAMEZAWA Hiroyuki 提交于
      Add dump_image_format[] to qemu.conf and support compressed dump
      at virsh dump. coredump compression is important for saving disk space
      in an environment where multiple guests run.
      
      In general, "disk space for dump" is specially allocated and will be
      a dead space in the system. It's used only at emergency. So, it's better
      to have both of save_image_format and dump_image_format. "save" is done
      in scheduled manner with enough calculated disk space for it.
      
      This code reuses some of save_image_format[] and supports the same format.

      qemu: Fix detection of drive readonly option · 69b75521
      Jiri Denemark 提交于
      So far, readonly=on option is used when qemu supports -device. However,
      there are qemu versions which support readonly option with -drive
      although they don't have support for -device.

      Add process= support for 'qemu-kvm -name' · c08c7b01
      John Morrissey 提交于
      This sets the process name to the same value as the Windows title,
      but since the name is limited to 16 chars only this is kept as a
      configuration option and turned off by default
      * src/qemu/qemu.conf src/qemu/qemu_conf.[ch]: hceck for support in the
        QEmu help output, add the option in qemu conf file and augment
        qemudBuildCommandLine to add it if switched on
      * src/qemu/libvirtd_qemu.aug src/qemu/test_libvirtd_qemu.aug: augment
        the augeas lenses accordingly
      * tests/qemuhelptest.c: cope with the extra flag being detected now

      Enable support for nested SVM · f98a6cd6
      Daniel P. Berrange 提交于
      This enables support for nested SVM using the regular CPU
      model/features block. If the CPU model or features include
      'svm', then the '-enable-nesting' flag will be added to the
      QEMU command line. Latest out of tree patches for nested
      'vmx', no longer require the '-enable-nesting' flag. They
      instead just look at the cpu features. Several of the models
      already include svm support, but QEMU was just masking out
      the svm bit silently. So this will enable SVM on such
      models
      
      * src/qemu/qemu_conf.h: flag for -enable-nesting
      * src/qemu/qemu_conf.c: Use -enable-nesting if VMX or SVM are in
        the CPUID
      * src/cpu/cpu.h, src/cpu/cpu.c: API to check for a named feature
      * src/cpu/cpu_x86.c: x86 impl of feature check
      * src/libvirt_private.syms: Add cpuHasFeature

      Implement support for virtio plan9fs filesystem passthrough in QEMU · a5c646a7
      Daniel P. Berrange 提交于
      Make use of the existing <filesystem> element to support plan9fs
      filesystem passthrough in the QEMU driver
      
          <filesystem type='mount'>
            <source dir='/export/to/guest'/>
            <target dir='/import/from/host'/>
          </filesystem>
      
      NB, the target is not actually a directory, it is merely a arbitrary
      string tag that is exported to the guest as a hint for where to mount
      it.

      Add support for -enable-kqemu flag · 6e44ec7a
      Daniel P. Berrange 提交于
      Previously QEMU enabled KQEMU by default and had -no-kqemu.
      0.11.x switched to requiring -enable-kqemu. 0.12.x dropped
      kqemu entirely. This patch adds support for -enable-kqemu
      so 0.11.x works. It replaces a huge set of if() with a
      switch() to make the code a bit more readable.
      
      * src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Support
        -enable-kqemu

      qemu: Allow setting boot menu on/off · 4f24ca01
      Cole Robinson 提交于
      Add a new element to the <os> block:
      
        <bootmenu enable="yes|no"/>
      
      Which maps to -boot,menu=on|off on the QEMU command line.
      
      I decided to use an explicit 'enable' attribute rather than just make the
      bootmenu element boolean. This allows us to treat lack of a bootmenu element
      as 'use hypervisor default'.

      Qemu arbitrary command-line arguments. · 869939a5
      Chris Lalancette 提交于
      Implement the qemu hooks for XML namespace data.  This
      allows us to specify a qemu XML namespace, and then
      specify:
      
      <qemu:commandline>
       <qemu:arg value='arg'/>
       <qemu:env name='name' value='value'/>
      </qemu:commandline>
      
      In the domain XML.
      
      Changes since v1:
       - Change the <qemu:arg>arg</qemu:arg> XML to <qemu:arg value='arg'/> XML
       - Fix up some memory leaks in qemuDomainDefNamespaceParse
       - Rename num_extra and extra to num_args and args, respectively
       - Fixed up some error messages
       - Make sure to escape user-provided data in qemuDomainDefNamespaceFormatXML
      
      Changes since v2:
       - Add checking to ensure environment variable names are valid
       - Invert the logic in qemuDomainDefNamespaceFormatXML to return early
      
      Changes since v3:
       - Change strspn() to c_isalpha() check of first letter of environment variable

      Explicitly represent balloon device in XML and handle PCI address · b2f18635
      Daniel P. Berrange 提交于
      To allow compatibility with older QEMU PCI device slot assignment
      it is necessary to explicitly track the balloon device in the
      XML. This introduces a new device
      
         <memballoon model='virtio|xen'/>
      
      It can also have a PCI address, auto-assigned if necessary.
      
      The memballoon will be automatically added to all Xen and QEMU
      guests by default.
      
      * docs/schemas/domain.rng: Add <memballoon> element
      * src/conf/domain_conf.c, src/conf/domain_conf.h: parsing
        and formatting for memballoon device. Always add a memory
        balloon device to Xen/QEMU if none exists in XML
      * src/libvirt_private.syms: Export memballoon model APIs
      * src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Honour the
        PCI device address in memory balloon device
