Core Dumping is disabled, but nevertheless a core dump has been created ? Where could i find it ? Would it be useful to provide it ?
So this really hints to qemu crashing. It certainly will be beneficial to collect the backtrace, but you really should report this (including the error message from the vm log file) to the qemu team.
They might have even fixed it by now, so a plain update might help.
Hi Peter, thanks for your help.
