      Stop accessing driver->caps directly in LXC driver · 64ec738e
      Michal Privoznik 提交于
      The 'driver->caps' pointer can be changed on the fly. Accessing
      it currently requires the global driver lock. Isolate this
      access in a single helper, so a future patch can relax the
      locking constraints.

      Introduce a virLXCDriverConfigPtr object · 7fca3755
      Michal Privoznik 提交于
      Currently the virLXCDriverPtr struct contains an wide variety
      of data with varying access needs. Move all the static config
      data into a dedicated virLXCDriverConfigPtr object. The only
      locking requirement is to hold the driver lock, while obtaining
      an instance of virLXCDriverConfigPtr. Once a reference is held
      on the config object, it can be used completely lockless since
      it is immutable.
      
      NB, not all APIs correctly hold the driver lock while getting
      a reference to the config object in this patch. This is safe
      for now since the config is never updated on the fly. Later
      patches will address this fully.

      virAsprintf: correctly check return value · 23e938ee
      Ján Tomko 提交于
      When virAsprintf was changed from a function to a macro
      reporting OOM error in dc6f2dad, it was documented as returning
      0 on success. This is incorrect, it returns the number of bytes
      written as asprintf does.
      
      Some of the functions were converted to use virAsprintf's return
      value directly, changing the return value on success from 0 to >= 0.
      
      For most of these, this is not a problem, but the change in
      virPCIDriverDir breaks PCI passthrough.
      
      The return value check in virhashtest pre-dates virAsprintf OOM
      conversion.
      
      vmwareMakePath seems to be unused.

      Wire up the new virDomainCreate{XML}WithFiles methods in the
      LXC driver, so that FDs get passed down to the init process.
      
      The lxc_container code needs to do a little dance in order

      Fix impl of virDomainCreateWithFlags remote client helper · ddaf15d7

      In the following commit:
      
        commit 03d813bb

          remote: fix dom->id after virDomainCreateWithFlags
      
      The virDomainCreateWithFlags remote client helper was made to
      invoke REMOTE_PROC_DOMAIN_LOOKUP_BY_UUID to refresh the 'id'
      of the domain, following the pattern used in the previous
      virDomainCreate method impl.
      
      The remote protocol for virDomainCreateWithFlags though did
      actually fix the design flaw in virDomainCreate, by directly
      returning the new domain info. For some reason, this data was
      never used. So we can just use that data now instead.

      Introduce new domain create APIs to pass pre-opened FDs to LXC · d76227be
      Daniel P. Berrange 提交于
      With container based virt, it is useful to be able to pass
      pre-opened file descriptors to the container init process.
      This allows for containers to be auto-activated from incoming
      socket connections, passing the active socket into the container.
      
      To do this, introduce a pair of new APIs, virDomainCreateXMLWithFiles
      and virDomainCreateWithFiles, which accept an array of file
      descriptors. For the LXC driver, UNIX file descriptor passing
      will be used to send them to libvirtd, which will them pass
      them down to libvirt_lxc, which will then pass them to the container
      init process.
      
      This will only be implemented for LXC right now, but the design
      is generic enough it could work with other hypervisors, hence
      I suggest adding this to libvirt.so, rather than libvirt-lxc.so

      esx: Support for disk-only and quiescing snapshots. · 6c8adeb4
      Geoff Hickey 提交于
      Add support for creating disk-only (no memory) snapshots in esx, and
      for quiescing the VM before taking the snapshot. The VMware API
      supports these operations directly, so adding support to libvirt is
      just a matter of setting the flags correctly when calling
      VMware. VIR_DOMAIN_SNAPSHOT_CREATE_DISK_ONLY and
      VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE are now valid flags for esx.

      libxl: implement virDomainGetNumaParameters · 261c4f5f
      Dario Faggioli 提交于
      Although, having it depending on Xen >= 4.3 (by using the proper
      libxl feature flag).
      
      Xen currently implements a NUMA placement policy which is basically
      the same as the 'interleaved' policy of `numactl', although it can
      be applied on a subset of the available nodes. We therefore hardcode
      "interleave" as 'numa_mode', and we use the newly introduced libxl
      interface to figure out what nodes a domain spans ('numa_nodeset').
      
      With this change, it is now possible to query the NUMA node
      affinity of a running domain:
      
      [raistlin@Zhaman ~]$ sudo virsh --connect xen:/// list
       Id    Name                           State

      [raistlin@Zhaman ~]$ sudo virsh --connect xen:/// numatune 23
