[libvirt] [PATCH v3 0/4] qemu: use FD passing for chardev UNIX sockets

This series makes use of the chardev fd passing arriving in QEMU 2.12 to get rid of the startup race wrt opening the QEMU monitor. It is actually enabled in all chardev UNIX sockets for sake of having the same codepath everywhere, but is only important for the monitor socket. Changed in v3: - Refactor UNIX socket opening code to allow it to be mocked in the unit tests to avoid creating real UNIX sockets Daniel P. Berrangé (4): qemu: probe for -chardev 'fd' parameter for FD passing qemu: support passing pre-opened UNIX socket listen FD qemu: don't retry connect() if doing FD passing qemu: remove pointless connect retry logic in agent src/qemu/qemu_agent.c | 84 ++----------------- src/qemu/qemu_capabilities.c | 4 +- src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 64 +++++++++++++- src/qemu/qemu_command.h | 4 + src/qemu/qemu_monitor.c | 54 +++++++----- src/qemu/qemu_monitor.h | 1 + src/qemu/qemu_process.c | 27 ++++-- .../caps_2.12.0.aarch64.xml | 1 + .../caps_2.12.0.ppc64.xml | 1 + .../caps_2.12.0.s390x.xml | 1 + .../caps_2.12.0.x86_64.xml | 1 + tests/qemumonitortestutils.c | 1 + .../disk-drive-write-cache.x86_64-latest.args | 3 +- ...irtio-scsi-reservations.x86_64-latest.args | 3 +- tests/qemuxml2argvmock.c | 16 ++++ 16 files changed, 153 insertions(+), 113 deletions(-) -- 2.17.0
