- Need little more info about how did you capture the blktrace. So you started blktrace and then started dd in parallel in all the three VMs and immediately system freezes and these are the only logs we see on console?
Almost ... The ssh connection through which I start the vmstat and/or blktrace never froze (not before, either). I can use that shell in the situation until I try accessing anything on a block device. So the blktrace was started before dd was started and blktrace was stopped (CTRL+C) while dd was still running. hth Dominik
