      Remove direct storage of hostnet_name & vlan · 0943048a
      Daniel P. Berrange 提交于
      The current way of assigning names to the host network backend and
      NIC device in QEMU was over complicated, by varying naming scheme
      based on the NIC model and backend type. This simplifies the naming
      to simply be 'net0' and 'hostnet0', allowing code to easily determine
      the host network name and vlan based off the primary device alias
      name 'net0'. This in turn allows removal of alot of QEMU specific
      code from the XML parser, and makes it easier to assign new unique
      names for NICs that are hotplugged
      
      * src/conf/domain_conf.c, src/conf/domain_conf.h: Remove hostnet_name
        and vlan fields from virNetworkDefPtr

      Remove use of -netdev arg with QEMU · 49a0f6cd
      Daniel P. Berrange 提交于
      The QEMU 0.12.x tree has the -netdev command line argument, but not
      corresponding monitor command. We can't enable the former, without
      the latter since it will break hotplug/unplug.

      Assign PCI addresses before hotplugging devices · d8acc446
      Daniel P. Berrange 提交于
      PCI disk, disk controllers, net devices and host devices need to
      have PCI addresses assigned before they are hot-plugged

        address and releasing unused addresses

      Rewrite way QEMU PCI addresses are allocated · 9258ec0a
      Daniel P. Berrange 提交于
      The current QEMU code allocates PCI addresses incrementally starting
      at 4. This is not satisfactory because the user may have given some
      addresses in their XML config, which need to be skipped over when
      allocating addresses to remaining devices.
      
      It is thus neccessary to maintain a list of already allocated PCI
      addresses and then only allocate ones that remain unused. This is
      also required for domain device hotplug to work properly later.
      
      * src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add APIs for creating
        list of existing PCI addresses, and allocating new addresses.
        Refactor address assignment to use this code
      * src/qemu/qemu_driver.c: Pull PCI address assignment up into the
        qemuStartVMDaemon() method, as a prelude to moving it into the
        'define' method. Update list of allocated addresses when connecting

      Make hotplug use new device_add where possible · 264e98d6
      Daniel P. Berrange 提交于
      Since QEMU startup uses the new -device argument, the hotplug
      code needs todo the same. This converts disk, network and
      host device hotplug to use the device_add command

      Introduce internal QEMU monitor APIs for drive + device hotadd · 5ec6cf7f
      Daniel P. Berrange 提交于
      The way QEMU is started has been changed to use '-device' and
      the new style '-drive' syntax. This needs to be mirrored in
      the hotplug code, requiring addition of two new APIs.

      Similar to the race fixed by
      be34c3c7, make sure
      to wait around for KVM to release the resources from
      a hot-detached PCI device before attempting to
      rebind that device to the host driver.

      Clarify controllers -device string in QEMU driver · 09080c38
      Matthew Booth 提交于
      The QEMU driver contained code to generate a -device string for piix4-ide, but
      wasn't using it. This change removes this string generation. It also adds a
      comment explaining why IDE and FDC controllers don't generate -device strings.
      
      The change also generates an error if a sata controller is specified for a QEMU
      domain, as this isn't supported.
      
      * src/qemu/qemu_conf.c: Remove VIR_DOMAIN_CONTROLLER_TYPE_IDE handler in
        qemuBuildControllerDevStr(). Ignore IDE and FDC controllers. Error if
        SATA controller is discovered. Add comments.

      Look in /usr/libexec for the qemu-kvm binary. · b16cd226
      Chris Lalancette 提交于
      On RHEL-5 the qemu-kvm binary is located in /usr/libexec.
      To reduce confusion for people trying to run upstream libvirt
      on RHEL-5 machines, make the qemu driver look in /usr/libexec
      for the qemu-kvm binary.
      
      To make this work, I modified virFindFileInPath to handle an
      absolute path correctly.  I also ran into an issue where
      NULL was sometimes being passed for the file parameter
      to virFindFileInPath; it didn't crash prior to this patch
      since it was building paths like /usr/bin/(null).  This
      is non-standard behavior, though, so I added a NULL
      check at the beginning.

      Support Xen 4.0 sysctl version 7 · 3bd3d6b0
      Jim Fehlig 提交于
      xen-unstable c/s 20762 bumped XEN_SYSCTL_INTERFACE_VERSION to 7.  The
      interface change does not affect libvirt, other than xenHypervisorInit()
      failing since version 7 is not tried.
      
      The attached patch accommodates the upcoming Xen 4.0 release by checking
      for XEN_SYSCTL_INTERFACE_VERSION 7.  If found, it sets
      XEN_DOMCTL_INTERFACE_VERSION to 6, which is also new to Xen 4.0.
