This patch series adds a new watchdog action `dump' which lets libvirtd can do auto-dump when receiving a watchdog event from qemu guest. In order to make the function work, there must be a watchdog device added to guest, and guest must have a watchdog daemon running, for example, /etc/init.d/watchdog start or auto-started on boot. Changes: v5: - qemu_driver is passed into threadpool as opaque parameter rather than visit the global qemu_driver in worker function - same situation as above of server in libvirtd.c - also list auto_dump_path in src/qemu/libvirtd_qemu.aug and src/qemu/test_libvirtd_qemu.aug - check return value of qemuDomainObjEndJob for safety v4: - updated threadpool to follow libvirt naming style, use appropriate internals APIs, and hide the struct definitions from the header (by Daniel) - fix an error that qemuDomainObjBeginJobWithDriver() get lost in qemuDomainCoreDump() - use thread pool in libvirtd (qemud worker) v3: - let default auto-dump dir be /var/lib/libvirt/qemu/dump Hu Tao (4): threadpool impl Add a new function doCoreDump Add a watchdog action `dump' Using threadpool API to manage qemud worker cfg.mk | 1 + daemon/libvirtd.c | 172 +++++------------------------ daemon/libvirtd.h | 2 + src/Makefile.am | 1 + src/conf/domain_conf.c | 1 + src/conf/domain_conf.h | 1 + src/libvirt_private.syms | 6 + src/qemu/libvirtd_qemu.aug | 1 + src/qemu/qemu.conf | 5 + src/qemu/qemu_conf.c | 16 +++- src/qemu/qemu_conf.h | 5 + src/qemu/qemu_driver.c | 228 ++++++++++++++++++++++++++++---------- src/qemu/test_libvirtd_qemu.aug | 2 + src/util/threadpool.c | 231 +++++++++++++++++++++++++++++++++++++++ src/util/threadpool.h | 48 ++++++++ 15 files changed, 518 insertions(+), 202 deletions(-) create mode 100644 src/util/threadpool.c create mode 100644 src/util/threadpool.h -- 1.7.3 -- Thanks, Hu Tao -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
