------- Comment From jos...@br.ibm.com 2017-12-01 12:59 EDT------- Hi Kleber,
The error KVM: Failed to create TCE64 table for liobn 0x... is harmless so let's forget it. I tried hard to reproduce the error without success so far, so I'm going to ask you another favor. Could you generate a trace log and send me the results? # creates a file with * inside, it means that we want to capture all traceable events (since I don't have suspects for now). $ echo "*" > trace_all # runs QEMU with the extra parameter: qemu-system-ppc64le <your parameters> -trace events=trace_all 2> log_all.txt After you hit the issue, please gzip that log_all.txt (it's huge) and send it to me.
