When using cold snapshots nova will stop the instance while copying the
disk and bring it back once done. This is the normal behaviour and won't
happen if your system is capable of doing live snapshots (qemu >= 1.3.0
and libvirt >= 1.0.0).

I am not sure if this is a bug but I don't think its a correct behaviour.
when I create a snapshot type image from a running instance, the livirt will
be killed and restarted:
