Although QEMU could catch signal BUS to handle hardware memory corrupted event, sadly, QEMU just prints a little log and try to fix it silently.
In these patches, introduce a 'MEMORY_FAILURE' event with 4 detailed actions of QEMU, then uplayer could know what situaction QEMU hit and did. And further step we can do: if a host server hits a 'hypervisor-ignore' or 'guest-mce', scheduler could migrate VM to another host; if hitting 'hypervisor-stop' or 'guest-triple-fault', scheduler could select other healthy servers to launch VM. zhenwei pi (3): target-i386: seperate MCIP & MCE_MASK error reason iqapi/run-state.json: introduce memory failure event target-i386: post memory failure event to uplayer qapi/run-state.json | 46 ++++++++++++++++++++++++++++++++++++++++++++++ target/i386/helper.c | 30 +++++++++++++++++++++++------- target/i386/kvm.c | 5 ++++- 3 files changed, 73 insertions(+), 8 deletions(-) -- 2.11.0
