1. You can share directories between host and container at the time of creating the container, with the help of -B option.
Here’s the command to bind /home/user on the host to /home/user in the container:
```
lxc-create -n myContainer -t download -B /home/user:/home/user
```
The above command and method may not work on all versions of LXC or distributions.
1. Another method to share a directory between host and LXC container is by bind mounting.
First, stop your container:
```
lxc-stop -n myContainer
```
Then add the following line to the config file found usually in /var/lib/lxc/myContainer/config:
```
lxc.mount.entry = /home/user home/user none bind 0 0
```
Then, start your container:
```
lxc-start -n myContainer
```
Now, /home/user in your LXC container is the same as /home/user on your host. Any changes on the host is seen inside the container and vice-versa.
Note: Always take a backup before making any changes to configuration files.
