So I thought I'd use the config file to set an lxc.mount.entry= line to mount the iSCSI volume inside the container at boot time per the examples. I am using filesystem label to identify the mount target, which works fine in the host.

I haven't used it so don't know the detailed commands, but you should
be able to use iscsi over tcp, with a daemon running on the host.
iscsi over netlink will not work.

So per the manpage, something like

iscsiadm -m discoverydb -t st -p ${hostip}:port -I eth0 --discover

perhaps

iscsiadm -m discoverydb -t st -p 10.0.3.1:3260 -I eth0 --discover

should work.
