2015-11-12Finish non-postcopiable iterative devices before packageDr. David Alan Gilbert
Where we have iterable, but non-postcopiable devices (e.g. htab or block migration), complete them before forming the 'package' but with the CPUs stopped. This stops them filling up the package.

Add qemu_savevm_state_complete_postcopy to complement qemu_savevm_state_complete_precopy together with a new save_live_complete_postcopy method on devices. The save_live_complete_precopy method is called on all devices during a precopy migration, and all non-postcopy devices during a postcopy migration at the transition.

2015-11-10MIG_CMD_PACKAGED: Send a packaged chunk of migration streamDr. David Alan Gilbert
MIG_CMD_PACKAGED is a migration command that wraps a chunk of migration stream inside a package whose length can be determined purely by reading its header. The destination guarantees that the whole MIG_CMD_PACKAGED is read off the stream prior to parsing the contents. This is used by postcopy to load device state (from the package) while leaving the main stream free to receive memory pages.

2015-06-02monitor: Use trad. command interface for HMP pcie_aer_inject_errorMarkus Armbruster
All QMP commands use the "new" handler interface (mhandler.cmd_new). Most HMP commands still use the traditional interface (mhandler.cmd), but a few use the "new" one. Complicates handle_user_command() for no gain, so I'm converting these to the traditional interface. pcie_aer_inject_error's implementation is split into the hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The former is a peculiar crossbreed between HMP and QMP handler. On success, it works like a QMP handler: store QDict through ret_data parameter, return 0. Printing the QDict is left to pcie_aer_inject_error_print(). On failure, it works more like an HMP handler: print error to monitor, return negative number. To convert to the traditional interface, turn pcie_aer_inject_error_print() into a command handler wrapping around hmp_pcie_aer_inject_error(). By convention, this command handler should be called hmp_pcie_aer_inject_error(), so rename the existing hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

Commit 79ca616 (v1.6.0) accidentally disabled legacy x86-only HMP commands pci_add, pci_del: it defined CONFIG_PCI_HOTPLUG only as make variable, not as preprocessor macro, killing the code conditional on defined(CONFIG_PCI_HOTPLUG_OLD).

Fun: git-log hw/pci/pci-hotplug-old.c shows our faith in the backward compatibility god has been strong enough to sacrifice at its altar about a dozen times, but not strong enough to even once verify the legacy feature's still there, let alone works.

2014-06-23vl: allow other threads to do qemu_system_vmstop_requestPaolo Bonzini
There patch protects vmstop_requested with a lock and introduces qemu_system_vmstop_request_prepare. Together with the new call to qemu_vmstop_requested in vm_start, qemu_system_vmstop_request_prepare avoids a race where the VM could remain stopped even though the iostatus of a block device has already been set (for example). qemu_system_vmstop_request_prepare however also lets the caller thread delay observation of the state change until it has itself communicated that change to the user. This delay avoids any possibility of a wrong reordering of the BLOCK_IO_ERROR event and the subsequent STOP event.
