Not right now; I'm not entirely sure its even possible with LXD but I've
not dug into this in huge detail to date.

Its possible to block migrate as part of the live-migration process for
libvirt/kvm; With regards to live migration in LXD - this is definitely an
experimental feature right now; CRIU is improving all of the time and
live-migration might just work for your workload but there are lots of
common cases that probably don't.

I think this is probably OK right now, but its not something I've
personally tried as most of our validation for nova-lxd is based around
2.0.x series, which does not have support for storage pools + ceph.

nova-lxd is still a separate team and project:

   https://github.com/openstack/nova-lxd

so its a little different to main Nova development right now; a bug report
at:

   https://bugs.launchpad.net/nova-lxd

is a good place to start!
