Bind mounts can be used to make directories on the hardware node visible to the container.
== Filesystem layout ==OpenVZ uses two directories. Assuming our container is numbered 777, these directories are: * <code>VE_PRIVATE</code>: $VZDIR/private/777* <code>VE_ROOT</code>: $VZDIR/root/777 {{Note|<code>$VZDIR</code> is usually <code>/vz</code>, on Debian systems however this is <code>/var/lib/vz</code>. In this document this This is further referred to as <code>$VZDIR</code> -- substitute it with what how you have.}} can make host system's <code>VE_PRIVATE</code> is a place for all the container files. <code>VE_ROOT<mnt/code> is the mount point to which <code>VE_PRIVATEdisk</code> is mounted during container start (or when you run <code>vzctl mount</code> {{Warning|If you want directory available to do a bind mount for container, you need to '''use <code>VE_ROOT</code>''' (not <code>VE_PRIVATE</code>!) and '''make sure that container is mounted''' (this can be checked using <code>vzctl status</code>).}} == Mounting == Put a script in OpenVZ configuration directory (<code>/etc/vz/conf/</code>) with the name <code>''CTID''.mount</code> (where <code>''CTID''</code> is container ID, like 777). This script will be executed every time you run <code>vzctl mount</code> or <code>vzctl start</code> for a particular container. If you need to the same for all containers, use the global mount script named <code>vps.mount</code>. From any mount script you can use the following environment variables:* <code>${VEID}</code> -- container ID (like <code>777</code>).* <code>${VE_CONFFILE}</code> -- container configuration file (like <code>/etc/vz/conf/777.conf</code>) Now, in order to get the value of <code>VE_ROOT</code> you need to source both the global OpenVZ configuration file, and then the container configuration file, in that particular order. This is the same way vzctl uses to determine <code>VE_ROOT</code>. === Mount script example === Here is an example of such a mount script (it can either be <code>/etc/vz/conf/vps.mount</code> or <code>/etc/vz/conf/''CTID''.mount</code>)
<source lang="bash">
CTID=777
EOF
chmod +x /etc/vz/conf/${CTID}.mount
</source>
If you want read-only mount, add <code>-r</code> option to mount command.
