Re: [libvirt] [PATCH v2] qemu: Fix shutdown regression with buggy qemu

The commit that prevents disk corruption on domain shutdown (96fc4784177ecb70357518fa863442455e45ad0e) causes regression with QEMU 0.14.* and 0.15.* because of a regression bug in QEMU that was fixed only recently in QEMU git. The affected versions of QEMU do not quit on SIGTERM if started with -no-shutdown, which we use to implement fake reboot. Since -no-shutdown tells QEMU not to quit automatically on guest shutdown, domains started using the affected QEMU cannot be shutdown properly and stay in a paused state. This patch disables fake reboot feature on such QEMU by not using -no-shutdown, which makes shutdown work as expected. However, virDomainReboot will not work in this case and it will report "Requested operation is not valid: Reboot is not supported with this QEMU binary". --- src/qemu/qemu_capabilities.c | 8 ++++++++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 2 +- src/qemu/qemu_driver.c | 6 ++++++ 4 files changed, 16 insertions(+), 1 deletions(-)
