so, using ct- as prefix instead vm- could prevent that right ?

ct-100-1.raw

Yes. Else people can use it for KVM (we need a way to avoid that).

lxc needs that. But we store this information with 'pve.volid'.

We already do this: pve.volid ==> pve.volid

yes

we update when you change 'pve.volid'. It is not really necessary to 
do it at start time.
