ubuntu14.04 and ubuntu16.04. Maybe it not caused by the guest images,I
think.
Yes, a double free or corruption is very likely a bug of QEMU, not
the guest.
Can you post a backtrace of the crash?
Zhenhao, its better to post backtrace after installing debug symbols
for package qemu.
I am so sorry to said that, I have not installed this for qemu . So,all the
things I can get is here. I will install it and Thanks again for your
reminder. Could you give me more suggestions to help get its root cause
,when it is happend again.
OK, please try to install debug info packages and enable crash dump on your host
(by configuring 'ulimit -c' of the QEMU process, sysctl core_pattern, etc), then
wait for the next crash. It is really hard to guess the cause without looking at
the backtrace.
