Hi,
On the quest to have QEMU depriviledge, we need to make quite a few changes to
libxl. This patch series rework quite a few libxl feature to use libxl__ev_qmp,
which is the new asynchronous way of communicating with QEMU in libxl.
Unfortunately, some libxl functions (in the public API) are supposed to be
synchronous but are communicating with QEMU before returning. So those functions
are made asynchronous with an additional parameter `libxl_asyncop_how'.
Functions that are changes:
- libxl_domain_unpause
- libxl_domain_pause
- libxl_send_trigger
- libxl_set_vcpuonline
- libxl_retrieve_domain_configuration
- libxl_qemu_monitor_command
This series depends on both:
- [PATCH v2 0/9] libxl: New slow lock + fix libxl_cdrom_insert with QEMU depriv
- [PATCH 00/15] Some cleanup of libxl
Patch series available in this git branch:
