what exactly does the " -snapshot " command for qm create do? I was under the impression that the vm would use a snapshot of the VHD instead of directly loading it? I'm only asking because my VM's no longer start if they have been created with -snapshot=on, they get past the bios and freeze and their status in the web interface is "io-error". I can't seem to find anything in the logs but i may be looking at the wrong ones? my VM's will start with " -snapshot=off " this started this morning, I haven't looked at it in a week.
