Hi Daniel,
I have try ssh to COLO guest with 8 hours, not occurred this issue.
Please check your network/qemu configuration.
But I found another problem maybe related this issue, if no network
communication for a period of time(maybe 10min), the first message send to
guest have a chance with delay(maybe 1-5 sec), I will try to fix it when I have
time.
Thanks
Zhang Chen
