I do not investigate enough to touch that place. 3. fix 3 patch a) as suggested by Jiri * fix leaks * s/hint/error/g * don't show <NULL> in error message * take suggested code simplifications b) extra * print error string from qemu to log in case we have to drop it Nikolay Shirokovskiy (1): qemu: report block job errors from qemu to the user src/qemu/qemu_blockjob.c | 13 +++++++++-- src/qemu/qemu_blockjob.h | 3 ++- src/qemu/qemu_domain.c | 1 + src/qemu/qemu_domain.h | 1 + src/qemu/qemu_driver.c | 4 ++-- src/qemu/qemu_migration.c | 54 +++++++++++++++++++++++++++++++------------- src/qemu/qemu_monitor.c | 5 ++-- src/qemu/qemu_monitor.h | 4 +++- src/qemu/qemu_monitor_json.c | 4 +++- src/qemu/qemu_process.c | 4 ++++ 10 files changed, 68 insertions(+), 25 deletions(-) -- 1.8.3.1
