No, you should be able to take a snapshot both while it is running and
while it is off. However, they use different mechanisms so there could be
a bug in the online version. What version of qemu/kvm are you running?
Also, do you have apparmor enabled/running? If so, and if the apparmor policy
hasn't been updated, that might be the source of your problems.
