      Add virRandom() API to generate numbers with non-power-of-2 limit · aa5bd8b9
      Daniel P. Berrange 提交于
      The current virRandomBits() API is only usable if the caller wants
      a random number in the range [0, n-1) where n is a power of two.
      This adds a virRandom() API which generates a double in the
      range [0.0,1.0) with 48 bits of entropy. It then also adds a
      virRandomInt(uint32_t max) API which generates an unsigned
      in the range [0,@max)

      Fix timebomb in LIBVIRT_VERSION_INFO calculation · 3b0cd660
      Daniel P. Berrange 提交于
      The way LIBVIRT_VERSION_INFO is calculated has a timebomb that
      will cause us to accidentally break soname when we change the
      major version number to a non-zero value !
      
      Given CURRENT:REVISION:AGE, libtool will generate
      
         libvirt.so.($CURRENT-$AGE).$AGE.$REVISION
      
      We set CURRENT to be MAJOR+MINOR and AGE to $MINOR, so as
      soon as MAJOR changes to non-zero, we get libvirt.so.1
      as the soname, eg  1.3.9 would create libvirt.so.1.3.9
      Looks natural but is not ABI compatible with libvirt.so.0.x.y
      
      The fix is to set CURRENT to always be exactly the same
      as AGE. We want to have the major version reflected in
      the so symlinks though. So then we set AGE to MAJOR*1000+MINOR
      eg, so 1.3.9 would create libvirt.so.0.1003.9 and libvirt
      2.51.3 would create libvirt.so.0.2051.3

      json: fix interface locale dependency · 43bfa23e
      Martin Kletzander 提交于
      libvirt creates invalid commands if wrong locale is selected. For
      example with locale that uses comma as a decimal point, JSON commands
      created with decimal numbers are invalid because comma separates the
      entries in JSON. Fortunately even when decimal point is affected,
      thousands grouping is not, because for grouping to be enabled with
      *printf, there has to be an apostrophe flag specified (and supported).
      
      This patch adds specific internal function for converting doubles to
      strings with C locale.

      virsh: make 'help' command ignore spurious options · 86157b59
      Cole Robinson 提交于
      Similar to the previous patch, prepending 'help' to a partial
      command string doesn't cut us any slack.
      
      $ virsh help pool-define-as --name foo --type dir
      error: command 'help' doesn't support option --name
      
      This patch adds a few hacks to make 'help' ignore everything after the
      first data bit, so the above command shows help output for pool-define-as.

      virsh: Convert '<cmd> --help' to 'help <cmd>' · d2f97139
      Cole Robinson 提交于
      Often times I find myself halfway through typing a long command when
      I want to see 'help' output. I instinctively append '--help' to the
      command I'm typing, only to get an error:
      
          $ virsh vol-create-as foo --help
          error: command 'vol-create-as' doesn't support option --help
      
      This patch makes --help work in a pretty hacky way. One missing piece
      here is that --help isn't listed as an option in the actual 'help <cmd>'
      output, but maybe this can be a starting point for someone.

      build: fix binary location in stap files --with-driver-modules · 54264111
      Laine Stump 提交于
      libvirt_qemu_probes.stp stopped working after switching to a build
      that used --with-driver-modules. This was because the symbols listed
      int libvirt_qemu_probes.stp are no longer in $(bindir)/libvirtd, but
      are now in $(libdir)/connection-driver/libvirt_driver_qemu.so.
      
      This patch enhances dtrace2systemtap.pl (which generates the .stp
      files from .d files) to look for a new "module" setting in the
      comments of the .d file (similar to the existing "binary" setting),
      and to look for a --with-modules option. If the --with-modules option
      is set *and* a "module" setting is present in the .d file, the process
      name for the stap line is set to
      
         $libdir/$module
      
      If either of these isn't true, it reverts to the old behavior.
      
      src/Makefile.am was also modified to add the --with-modules option
      when the build calls for it, and src/libvirt_qemu_probes.d has added a
      "module" line pointing to the correct .so file for the qemu driver.

      nwfilter: fix crash during filter define when lxc driver failed startup · b8a56f12
      Laine Stump 提交于
      The meat of this patch is just moving the calls to
      virNWFilterRegisterCallbackDriver from each hypervisor's "register"
      function into its "initialize" function. The rest is just code
      movement to allow that, and a new virNWFilterUnRegisterCallbackDriver
      function to undo what the register function does.
      
      The long explanation:
      
      There is an array in nwfilter called callbackDrvArray that has
      pointers to a table of functions for each hypervisor driver that are
      called by nwfilter. One of those function pointers is to a function
      that will lock the hypervisor driver. Entries are added to the table
      by calling each driver's "register" function, which happens quite
      early in libvirtd's startup.
      
      Sometime later, each driver's "initialize" function is called. This
      function allocates a driver object and stores a pointer to it in a
      static variable that was previously initialized to NULL. (and here's
      the important part...) If the "initialize" function fails, the driver
      object is freed, and that pointer set back to NULL (but the entry in
      nwfilter's callbackDrvArray is still there).
      
      When the "lock the driver" function mentioned above is called, it
      assumes that the driver was successfully loaded, so it blindly tries
      to call virMutexLock on "driver->lock".
      
      BUT, if the initialize never happened, or if it failed, "driver" is
      NULL. And it just happens that "lock" is always the first field in
      driver so it is also NULL.
      
      Boom.
      
      To fix this, the call to virNWFilterRegisterCallbackDriver for each
      driver shouldn't be called until the end of its (*already guaranteed
      successful*) "initialize" function, not during its "register" function
      (which is currently the case). This implies that there should also be
      a virNWFilterUnregisterCallbackDriver() function that is called in a
      driver's "shutdown" function (although in practice, that function is
      currently never called).

      An ESX server has one or more PhysicalNics that represent the actual
      hardware NICs. Those can be listed via the interface driver.
      
      A libvirt virtual network is mapped to a HostVirtualSwitch. On the
      physical side a HostVirtualSwitch can be connected to PhysicalNics.
      On the virtual side a HostVirtualSwitch has HostPortGroups that are
      mapped to libvirt virtual network's portgroups. Typically there is
      HostPortGroups named 'VM Network' that is used to connect virtual
      machines to a HostVirtualSwitch. A second HostPortGroup typically
      named 'Management Network' is used to connect the hypervisor itself
      to the HostVirtualSwitch. This one is not mapped to a libvirt virtual
      network's portgroup. There can be more HostPortGroups than those
      typical two on a HostVirtualSwitch.

      The static deep copy allocates storage for the copy. The dynamic

      triggered the invalid argument check in the dynamically dispatched
      deep copy call. The deep copy function expects its dest parameter
      to be a pointer to a NULL-pointer. This expectation wasn't met due
      to the dispatching deep copy doing the allocation before the call.

      This patch refactors the JSON parsing function that extracts the block
      IO tuning parameters from qemu's output. The most impacting change
      concerns the error message that is returned if the reply from qemu does
      not contain the needed data. The data for IO parameter tuning were added
      in qemu 1.1 and the previous error message was confusing.
      
      This patch also breaks long lines and extracts a multiple time used code
      pattern to a macro.

      remote: Clean up coding style and refactor remote connection opening · 6758ad4f
      Peter Krempa 提交于
      Remove spaces before function calls and some other coding nits in some
      parts of the remote driver and refactor getting of URI argument
      components into variables used by libvirt later on.

      Allow rbd backing stores · 16d3ab86
      Peter Feiner 提交于
      Prevents libvirt from treating RBD backing stores as files. Without this
      patch, creating a domain with a qcow2 overlay on an RBD would fail.
      
      This patch essentially extends 9c7c4a4f,
      which allows nbd backing stores, to allow rbd backing stores.

      Fix errno check, prevent spurious errors under heavy load · bfa74ebe
      Peter Feiner 提交于
      From man poll(2), poll does not set errno=EAGAIN on interrupt, however
      it does set errno=EINTR. Have libvirt retry on the appropriate errno.
      
      Under heavy load, a program of mine kept getting libvirt errors 'poll on
      socket failed: Interrupted system call'. The signals were SIGCHLD from
      processes forked by threads unrelated to those using libvirt.

      qemu: add two qemu caps for lsi and virtio-scsi SCSI controllers · 015c603b
      Guannan Ren 提交于
      Rename qemuDefaultScsiControllerModel to qemuCheckScsiControllerModel.
      When scsi model is given explicitly in XML(model > 0) checking if the
      underlying QEMU supports it or not first, raise an error on checking
      failure.
      When the model is not given(mode <= 0), return LSI by default, if
      the QEMU doesn't support it, raise an error.

      util: include stderr in log message when an external command fails · b8c298d3
      Laine Stump 提交于
      This patch is in response to:
      
        https://bugzilla.redhat.com/show_bug.cgi?id=818467
      
      If a caller to virCommandRun doesn't ask for the exitstatus of the
      program it's running, the virCommand functions assume that they should
      log an error message and return failure if the exit code isn't
      0. However, only the commandline and exit status are logged, while
      potentially useful information sent by the program to stderr is
      discarded.
      
      Fortunately, virCommandRun is already checking if the caller had asked
      for stderr to be saved and, if not, sets things up to save it in
      *cmd->errbuf. This makes it fairly simple for virCommandWait to
      include *cmd->errbuf in the error log (there are still other callers
      that don't setup errbuf, and even virCommandRun won't set it up if the
      command is being daemonized, so we have to check that it's non-zero).
