      Fix USB passthrough based on product/vendor · 09ed0729

      Changeset
      
        commit 5073aa99
        Author: Cole Robinson <crobinso@redhat.com>
        Date:   Mon Jan 11 11:40:46 2010 -0500
      
      Added support for product/vendor based passthrough, but it only
      worked at the security driver layer. The main guest XML config
      was not updated with the resolved bus/device ID. When the QEMU
      argv refactoring removed use of product/vendor, this then broke
      launching guests.
      
      THe solution is to move the product/vendor resolution up a layer
      into the QEMU driver. So the first thing QEMU does is resolve
      the product/vendor to a bus/device and updates the XML config
      with this info. The rest of the code, including security drivers
      and QEMU argv generated can now rely on bus/device always being
      set.
      
      * src/util/hostusb.c, src/util/hostusb.h: Split vendor/product

      Tweak container initialization to make upstart/init happier · b70a1f45

      Upstart crashes & burns in a heap if $TERM environment variable
      is missing. Presumably the kernel always sets this when booting
      init on a real machine, so libvirt should set it for containers
      too.

      symlink the primary console /dev/pts/0 to /dev/tty1.

      Misc fixes for LXC cgroups setup · 57db02e8
      Daniel P. Berrange 提交于
      When using the 'ns' cgroup controller, the moment a process calls
      'unshare(CLONE_NEWNS)', it will be given a private cgroup tree
      under its current location. This really messages up the LXC
      controller process, because it ends up creating the containers'
      cgroup in the wrong place. The fix is fairly easy, just move
      the cgroup setup before the code which calls unshare(). The
      'ns' controller will still create extra undesired cgroups, but
      they at least won't break libvirt's setup now.
      
      The patch also adds a missing cgroups allow rule for /dev/tty
      device node

      Change default for storage uid/gid from getuid()/getgid() to -1/-1 · 219305df
      Laine Stump 提交于
      This allows the config to have a setting that means "leave it alone",
      eg when building a pool where the directory already exists the user
      may want the current uid/gid of the directory left intact. This
      actually gets us back to older behavior - before recent changes to the
      pool building code, we weren't as insistent about honoring the uid/gid
      settings in the XML, and virt-manager was taking advantage of this
      behavior.
      
      As a side benefit, removing calls to getuid/getgid from the XML
      parsing functions also seems like a good idea. And having a default
      that is different from a common/useful value (0 == root) is a good
      thing in general, as it removes ambiguity from decisions (at least one
      place in the code was checking for (perms.uid == 0) to see if a
      special uid was requested).
      
      Note that this will only affect newly created pools and volumes. Due
      to the way that the XML is parsed, then formatted for newly created
      volumes, all existing pools/volumes already have an explicit uid and
      gid set.
      
      src/conf/storage_conf.c: Remove calls to setuid/setgid for default values
                               of uid/gid, and set them to -1 instead

      QEMU has a monitor command 'set_cpu' which allows a specific
      CPU to be toggled between online& offline state. libvirt CPU

      Make domain save work on root-squash NFS · 3c12a67b
      Laine Stump 提交于
      Move *all* file operations related to creation and writing of libvirt
      header to the domain save file into a hook function that is called by
      virFileOperation. First try to call virFileOperation as root. If that
      fails with EACCESS, and (in the case of Linux) statfs says that we're
      trying to save the file on an NFS share, rerun virFileOperation,
      telling it to fork a child process and setuid to the qemu user. This
      is the only way we can successfully create a file on a root-squashed
      NFS server.

      Introduce support for  virDomainGetJobInfo in the QEMU driver. This
      allows for monitoring of any API that uses the 'info migrate' monitor
      command. ie virDomainMigrate, virDomainSave and virDomainCoreDump
      
      Unfortunately QEMU does not provide a way to monitor incoming migration
      so we can't wire up virDomainRestore yet.
      
      The virsh tool gets a new command 'domjobinfo' to query status
      
      * src/qemu/qemu_driver.c: Record virDomainJobInfo and start time
        in qemuDomainObjPrivatePtr objects. Add generic shared handler
        for calling 'info migrate' with all migration based APIs.
      * src/qemu/qemu_monitor_text.c: Fix parsing of 'info migration' reply
      * tools/virsh.c: add new 'domjobinfo' command to query progress
