thank you for reporting this. however, I failed to find anything suspicious in the dmesg.
Was the guest instance killed? What did the guest kernel log say? would you please also have the guest kernel log attached?

PS, specifying "-serial stdio" in qemu cmdline, and "console=ttyS0" in guest kernel cmdline, will make you able to get the guest dmesg via qemu stdout.
